Indoor slate
You want a non-drying mineral oil for slate or a board, and you will check the bottle. Brandon Bespoke, 500 ml, is about £11.95, with 4.7 from 1,538 reviews. The title says food safe. It does not cure.
Stone oil comparison 2026
The best stone oils, compared.
Top pick: Osmo 620 stone and terracotta oil 0.75 L Best value: Lubrisolve mineral oil 2 litres – Lowest price per litre among the mineral oils here, about £16.99 for 2 litres, with slate and stone named and 4.6 from 155 reviews. Updated October 2026.
Stone oil on amazon.co.uk is not one finish. Most of these twelve listings are non-drying mineral oil for wooden boards, also named for slate or stone. Osmo 620 is a thin exterior oil for absorbent stone and terracotta. Linseed and tung oil harden in the air, so piled cloths can self-heat. A nano spray and a honing oil answer different jobs. If food will touch the surface, the bottle in your hand and the listing must agree. Assimilated Regulation 1935/2004, as the Food Standards Agency explains it, is the general duty, not a badge on the tin. A stored UK review of says the bottle read for external use only while the listing said food safe. Read the label before the oil goes near a board or a slate worktop. The split by chemistry is in the [stone oil buying guide](/hub/paints-and-varnishes/stone-oil/sub/stone-oil-buying-guide). Materialix boiled linseed is a drying timber oil whose bullets do not name stone.

Which stone oil fits?
Question 1 of 2
What are you treating?
The best stone oils in detail
Our view
Osmo 620 is the clearest specialist option here for exterior absorbent stone and terracotta. The 0.75-litre tin gives a clear satin finish, while the manufacturer’s UK guidance calls for very thin coats and removal of all unabsorbed oil. UK reviewers report successful use on sandstone steps, terracotta patios and tiled porches. One reviewer also found that oil pooled in pitted stone and dried as white patches, which makes careful wipe-off essential. Its 5.0 rating looks impressive but comes from only 14 reviews, so it should not outweigh surface suitability. Use it outside on absorbent stone, not as a default treatment for an indoor slate worktop.
Pros
- Purpose-made for exterior stone and terracotta
- Clear satin finish
- Positive UK use reports on patios and steps
Cons
- Only 14 Amazon ratings
- Pooled oil can leave white marks
- Not for non-absorbent stone
Best for: Exterior absorbent stone, sandstone steps and terracotta patios after a successful test patch.
Less suitable: Indoor food worktops, polished stone or surfaces that do not absorb oil.

Common questions
Does the amazon.co.uk file state coverage?
No. There is no bullet block and no coverage figure. The title has 620 and 0.75 litre. Osmo UK states about 32 m² per litre on smooth surfaces. That figure is not your stone.
What did UK reviewers use it on?
Sandstone steps, a terracotta patio and a tiled porch. Pooled oil left white areas on pitted stone.
Does the file answer the limestone question?
The page asks. The stored amazon.co.uk file does not answer.
Our view
Materialix packages 500 ml of food-grade mineral oil as two 250 ml bottles, which is convenient for storage and controlled use. The listing names stone and slate alongside wood, bamboo and stainless steel, and the 4.7 rating is backed by 6,096 reviews. UK reviewers describe applying it with a cloth and waiting between coats, although one disputes the listing’s odourless description. At £17.90, it is more expensive per litre than Lubrisolve and the single 500 ml Brandon Bespoke bottle. The listing also warns never to overheat the oil because its vapours are highly flammable; this is different from the self-heating rag risk of linseed oil. It is a strong choice when two smaller bottles are more useful than the cheapest bulk pack.
Pros
- Two manageable 250 ml bottles
- Names slate and stone
- 4.7 rating from 6,096 reviews
Cons
- Costs more per litre than larger mineral-oil packs
- One reviewer reported an odour
- Must not be overheated
Best for: Indoor slate, stone or board maintenance where split bottles are convenient.
Less suitable: The lowest-cost bulk purchase or a surface requiring a cured exterior coating.

No. The listing says odourless. One stored UK review said it had an odour.

Our view
Brandon Bespoke combines a useful 500 ml size with a listing that names wood, worktops, slate and stone. At £11.95, it is cheaper than the other 500 ml mineral oils here, while its 4.7 rating is backed by 1,538 reviews. The non-drying oil is straightforward to apply sparingly and buff, making it a sensible maintenance treatment where the worktop supplier permits mineral oil. It will deepen the surface appearance but will not become a hard, stain-proof sealer. One stored UK review also highlights a swallow warning and the lack of a child-resistant lid, so storage deserves care. This is our top pick for a versatile mid-sized mineral oil, subject to checking the bottle label against the intended food-contact use.
Pros
- Strong 4.7 rating from 1,538 reviews
- Names slate, stone and worktops
- Good-value 500 ml size
Cons
- No child-resistant lid noted by one reviewer
- Non-drying finish needs periodic maintenance
Best for: Indoor slate, stone and wooden worktops where the supplier and bottle label permit mineral oil.
Less suitable: Homes unable to store the bottle securely or surfaces requiring a cured exterior finish.

Our view
Bartoline provides 5 litres of raw linseed oil for £27.29, or about £5.46 per litre, for large timber, terracotta and stone-floor projects. The maker’s guidance calls for two or three coats with about 24 hours between them and roughly a week for drying, so this is not a quick weekend wipe-over. Its 4.7 rating from 536 reviews is strong, although one UK reviewer reports a fishy smell. The product information names stone floors and terracotta but does not provide a food-contact declaration for a kitchen worktop. Used cloths can self-heat as the oil oxidises and must be handled according to the fire-safety warning. It is a good-value floor oil when you accept the drying time, smell and cloth routine.
Pros
- Very low price per litre
- Names terracotta and stone floors
- Strong 4.7 rating from 536 reviews
Cons
- About a week to dry
- Cloths present a self-heating fire risk
- No stored food-contact claim
Best for: Large compatible stone-floor, terracotta or outdoor timber projects.
Less suitable: Indoor food worktops, small jobs or projects that need rapid drying.

Common questions
Does the listing mention cloth fires?
Yes. A bullet says dispose of application cloths to prevent fire hazards.
Is stone named?
Yes. The title names stone, and the bullets name stone floors such as terracotta.
Why is the stored weight odd?
The file stores 484 g for a 5 litre pack. That cannot be the oil mass. It is kept as listed.
Our view
Materialix boiled linseed oil is a 1-litre drying oil aimed mainly at worktops, blocks, furniture and outdoor wood. The listing claims around 18 hours to dry and five to ten days to harden, which makes the time commitment much clearer than on many bottles here. Its 4.7 rating from 433 reviews is reassuring, but UK reviewers mention a strong smell and a tin that is awkward to pour. Crucially for this comparison, the stored bullets do not name stone or slate. The food-contact claim refers to a cited laboratory standard, but the certificate is not in the stored evidence. Choose it for compatible timber only after reading the delivered label, and manage used cloths as a drying-oil fire risk.
Pros
- Clear drying and hardening times
- One-litre pack
- Strong Amazon rating
Cons
- Stone is not named in the bullets
- Strong smell reported
- Tin can be difficult to pour
Best for: Compatible wooden worktops, blocks, furniture or outdoor timber where a drying finish is wanted.
Less suitable: Stone or slate unless the manufacturer separately confirms suitability.

Common questions

A strong smell, a tin that is hard to pour, and uncertainty about how long the finish lasts.
Our view
Grain Guard is a practical 500 ml mineral oil for small indoor slate, wood or bamboo jobs where the bottle in hand confirms the intended use. The listing describes it as colourless, unscented and suitable for food-preparation surfaces, and application is simply by cloth. Because mineral oil does not cure, it can deepen the appearance without becoming a hard protective sealer. Its 4.7 rating is encouraging, although 80 reviews provide less evidence than the established Brandon Bespoke and Materialix listings. At £13.99 it also costs more per litre than the 2-litre Lubrisolve pack. Choose it for a manageable bottle rather than for outdoor weather protection.
Pros
- Names slate as well as wood and bamboo
- Food-contact claim on the UK listing
- Unscented 500 ml format
Cons
- Does not cure into a hard finish
- Higher price per litre than the 2-litre Lubrisolve pack
Best for: Small indoor slate, chopping-board and bamboo maintenance jobs where the label matches the surface.
Less suitable: Exterior paving, non-absorbent stone or anyone wanting a cured sealer.

The bullets say there is no curing time. They do not give a drying hour.
Our view
Lansky honing oil belongs on sharpening stones, not on slate worktops, patios or masonry. The 120 ml bottle is designed for Lansky sharpeners and Arkansas bench stones, where a few drops help carry away sharpening debris. Its 4.6 rating from 3,600 reviews is substantial evidence for that narrow job, but it says nothing about performance as a decorative stone finish. UK reviewers say a little goes a long way, although some consider the volume expensive and one found the cap awkward. There is no stored food-contact or outdoor-finish claim. Buy it with a compatible oil stone and ignore it for every worktop or paving project in this comparison.
Pros
- Large review base for sharpening use
- A few drops are sufficient
- Purpose-specific formula
Cons
- Not a worktop or masonry finish
- Small volume for the price
- One reviewer found the cap awkward
Best for: Lubricating compatible Lansky and Arkansas sharpening stones.
Less suitable: Slate worktops, stone floors, patios or any decorative sealing job.

A little goes a long way. Some call the volume expensive. One review says the cap is awkward.
Our view
Brandon Bespoke tung oil is a drying oil for buyers who want a matt finish rather than the permanently non-drying behaviour of mineral oil. Its listing names wood, slate and stone and allows indoor or outdoor use, while reviews describe several coats with overnight waits. The 4.6 rating from 394 reviews gives a reasonable evidence base. Application requires more patience than a wipe-and-buff mineral oil, and the coverage figures in the listing contradict each other, so they should not guide quantity. One UK reviewer still noticed the smell in a camper three weeks later. Treat used cloths with the same care as other oxidising drying oils and test the surface before committing.
Pros
- Matt drying finish
- Names slate and stone
- Suitable for indoor and outdoor jobs as listed
Cons
- Several coats and waiting periods
- Conflicting coverage figures
- Persistent smell reported by one reviewer
Best for: A compatible wood or stone surface where a matt drying-oil finish is wanted.
Less suitable: Quick maintenance, poorly ventilated rooms or anyone wanting a non-drying food-surface oil.

Our view
Lubrisolve supplies 2 litres of colourless mineral oil for £16.99, making it the best value among the comparable mineral oils in this set at about £8.50 per litre. The listing names slate and stone as well as boards, blocks and utensils, and states that the oil is suitable for direct food contact. A UK reviewer describes rubbing it in, leaving it overnight and wiping off the excess, which suits a non-drying maintenance oil. Its 4.6 rating from 155 reviews is credible, though not as deep a review base as Brandon Bespoke’s 500 ml bottle. The large pack is economical only if you will use it before it becomes workshop clutter. It does not cure or replace a specified impregnating sealer.
Pros
- Lowest price per litre among the mineral oils
- Listing names slate and stone
- Food-contact claim on the UK listing
Cons
- Large pack for a one-off job
- Does not form a cured protective layer
Best for: Regular maintenance of compatible slate, stone, boards or utensils where a large pack is useful.
Less suitable: A single small surface or exterior stone needing a weather-resistant treatment.

DD teck is a 100 ml mineral-oil bottle for trying a small board, worktop or slate area without buying much surplus. The listing describes it as transparent and odourless and cites BP/USP standards alongside a food-safe claim. A UK reviewer reports using only a tiny quantity on a board, which supports the value of the small bottle for occasional maintenance. At £5.99, however, it works out at about £60 per litre and is poor value for a large stone surface. Its 4.6 rating is based on only 28 reviews, so the evidence base is modest. The broad lubrication and rust-protection claims also make checking the exact label for your intended food surface important.
Pros
- Low initial price
- Small quantity suits a trial or occasional use
- Listing names slate and stone
Cons
- About £60 per litre
- Only 28 Amazon reviews
- Broad multi-purpose positioning
Best for: A small trial patch or occasional maintenance where 100 ml is enough.
Less suitable: Large worktops, floors or buyers seeking the lowest cost per litre.

Our view
Ourons is a small 100 ml bottle of white mineral oil aimed at chopping boards, blocks and utensils. It has a 4.5 rating from 427 reviews and a low £5.99 purchase price, but that becomes about £60 per litre. More importantly, a stored UK reviewer says the bottle was marked for external use only even though the listing called the oil food safe. That conflict is a reason to inspect the delivered label before the oil goes near any food-preparation surface. Stone and slate are not named in the stored bullets, which further weakens its fit for this comparison. The bottle may suit a tiny board-care job only when the physical label clearly supports that use.
Pros
- Low initial price
- Convenient 100 ml bottle
- Odourless and colourless as listed
Cons
- Listing and reported bottle label conflict
- Stone is not named in the bullets
- High price per litre
Best for: A very small board-care job only if the delivered label confirms the intended use.
Less suitable: Slate worktops or any food-contact use when the label does not agree with the listing.

Our view
Nano Z is a 400 ml water-based spray sealer rather than a stone oil, so it answers a different need from the mineral, linseed and tung products here. Its listing names stone, concrete, marble, limestone, granite and terracotta and describes an invisible water- and oil-repellent coating. That breadth may appeal when you want a spray treatment rather than colour-deepening oil. However, the stored evidence includes only one UK-labelled review body among nine, so most of the available comments do not represent UK experience. The 3.6 rating from 32 reviews is also the weakest rating in this set. It is worth considering only after a test patch and after checking that the surface supplier permits this type of sealer.
Pros
- Names several masonry surfaces
- Water-based spray format
- Designed to leave a clear appearance
Cons
- Not a stone oil
- Limited UK review evidence
- No food-contact claim in the stored listing
Best for: Buyers specifically seeking a water-repellent spray for a compatible masonry surface.
Less suitable: Food-preparation surfaces or shoppers looking for a traditional oil finish.

Stone oil buying guide
Stone oil on these twelve amazon.co.uk listings is not one product. Mineral oil, raw linseed, boiled linseed, tung oil, Osmo 620, a water-based spray and honing oil sit in the same search and do different jobs. Read the surface, whether the liquid cures, and whether the bottle agrees with any food-contact line before you read the stars. Prices below are the mid-October 2026 extracts. Nothing here is a laboratory ranking.
What is stone oil?
Stone oil, on these amazon.co.uk listings, is a name shoppers use for several different liquids. Most bottles are non-drying mineral oil for wooden boards, with slate or stone also in the title. Osmo 620 is a thin exterior oil for absorbent stone and terracotta. Bartoline raw linseed and Brandon Bespoke tung oil harden in the air. Materialix boiled linseed is a drying timber oil whose bullets do not name stone. Nano Z is a water-based spray. Lansky is honing oil for a sharpening stone.
Best for
- Indoor slate or a food board, where a non-drying mineral oil is named and the bottle matches the listing
- Exterior absorbent stone or terracotta, where you will wipe off excess Osmo 620 or accept a slow linseed dry
Not ideal for
- Polished or non-absorbent stone, and any food surface where the bottle disagrees with the listing
- A sharpening stone, which wants honing oil, or a damp patio that needs a professional
Mistakes to avoid
- 1
Leaving a thick coat in pits
Osmo UK asks for two thin coats and for unabsorbed oil to be wiped off. A UK review links oil left in pitted stone to white marks. Mineral oil is also wiped off after it has soaked. A flooded coat is not a stronger finish.
- 2
Trusting a food-safe title alone
Ourons is listed as food safe, and a stored UK review says the bottle read for external use only. Bartoline is not food safe because a reviewer said so. Read the label in your hand. Regulation 1935/2004 is the general duty, not a badge on every tin.
- 3
Binning a screwed-up drying-oil cloth
Linseed and tung oil oxidise, and piled cloths can ignite. Spread them, soak them, or keep them under water in a metal tin, outdoors. Mineral oil does not oxidise that way. Do not overheat mineral oil: Materialix warns that the vapour is highly flammable.
What to weigh up
Surface, chemistry and food contact
HighName the job before the brand. Indoor slate or a food board, outdoor absorbent stone, a drying timber finish, a water-repellent spray and a sharpening stone are five jobs. Brandon Bespoke mineral oil is the top pick for the first of those because 1,538 reviews support a 500 ml bottle whose title names wood, slate and stone. It is the wrong tin if you need a cured patio oil. Osmo 620 is the exterior specialist, and 14 ratings do not outweigh a surface that will not absorb oil.
Pack size, sample and cloths
HighPrice per litre sorts the shelf better than the ticket price. DD teck and Ourons are about £5.99 for 100 ml, about £60 a litre. Lubrisolve at about £16.99 for 2 litres is about £8.50 a litre, which is why it is the best value among the mineral oils. Bartoline at about £27.29 for 5 litres is about £5.46 a litre, and it is raw linseed for floors, not a worktop conditioner. Osmo at about £26 buys 0.75 litre of exterior oil. The maker’s 32 m² figure is for smooth surfaces, not your patio.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
Absorbent patio
You are oiling sandstone or terracotta outside, and you will wipe off the excess. Osmo 620, 0.75 litre, is about £26, with 5.0 from 14 reviews. Non-absorbent stone is out. It is not the indoor worktop tin.
Regular mineral oil
You will use a large pack on boards, slate or stone. Lubrisolve, 2 litres, is about £16.99, about £8.50 a litre, with 4.6 from 155 reviews. The food-contact line is the seller’s claim. It does not cure.
Common questions about stone oils
What is the top pick in this stone oil comparison?
The top pick is Brandon Bespoke mineral oil, 500 ml, at about £11.95. Amazon.co.uk shows 4.7 from 1,538 reviews, the largest review base among the mineral oils here that name slate or stone. The title says food safe and names wood, slate and stone. The oil does not cure, so you renew it. One UK review notes a swallow warning and no child-resistant lid. This score ranks the listings on the page. It is not a laboratory test.
Which listing is the best value?
The best value is Lubrisolve mineral oil, 2 litres, at about £16.99. That is about £8.50 a litre, the lowest price per litre among the mineral oils in this set. The listing names boards, utensils, slate and stone, and it says the oil is certified for direct food contact. That sentence is the seller’s claim. Amazon.co.uk shows 4.6 from 155 reviews. A 2 litre pack is a poor buy if you only treat one small board. The £5.99 bottles are 100 ml, about £60 a litre.
What is the difference between mineral oil and linseed?
Mineral oil does not cure. It deepens slate or a board, and you wipe it on again after washing. Linseed and tung oil oxidise and harden. Bartoline raw linseed, 5 litres at about £27.29, names stone floors and terracotta, with about a day between coats and about a week to dry. Materialix boiled linseed names wood, not stone, and claims about 18 hours to dry. Piled linseed or tung cloths can self-heat. Mineral-oil cloths are not that case.
Can I use these oils on a slate worktop?
Only if the listing names that surface and the bottle agrees. Brandon Bespoke, Lubrisolve, Grain Guard, DD teck, Materialix mineral oil and Brandon tung oil name slate or stone. Ourons bullets name boards and utensils, not stone. Materialix boiled linseed does not name stone. Osmo 620 is an exterior oil for absorbent stone, not the default for an indoor food worktop. A warranted worktop may have its own care sheet. Follow that before any of these tins.
Are oily cloths a fire risk?
Linseed and tung oil oxidise. East Sussex Fire and Rescue Service says piled oily rags can ignite. Northamptonshire Fire and Rescue Service recorded a 2020 domestic call from oil-cloth combustion. Bartoline’s safety data sheet carries the same cloth warning. Spread the cloths, soak them, or keep them under water in a metal tin, outdoors. Use that care for tung oil and boiled linseed. Mineral oil does not oxidise that way. Materialix warns that overheated mineral-oil vapour is highly flammable. This page did not run a burn test.
Is Osmo 620 the same as mineral oil?
No. Osmo 620 is a clear satin exterior oil for absorbent stone and terracotta, 0.75 litre at about £26, with 5.0 from 14 reviews. Osmo UK states about 32 m² per litre on smooth surfaces, two thin coats, excess wiped off, and about 8–10 hours to dry. That coverage is the maker’s figure for smooth surfaces, not a promise for your stone. Non-absorbent stone is out. A UK review links pooled oil in pits to white marks. Mineral oil does not form that satin coat.
Is the nano spray or the honing oil a stone oil?
Nano Z, 400 ml at about £24, is a water-based spray sealer, not an oil. The listing names stone, concrete, marble, limestone, granite and terracotta. The rating is 3.6 from 32 reviews, and most stored review bodies are from the United States, so they are not UK experience. There is no food-contact claim in the stored listing. Lansky honing oil, 120 ml at about £8.40, is for Lansky and Arkansas sharpening stones. A 4.6 from 3,600 reviews supports that job only. Do not use it on a worktop.
When should I stop and get help?
Stop if the patio is damp or flaking, if a worktop warranty names its own cleaner, or if an old wall holds moisture. Polished stone that will not absorb oil, and cooking oil on a board, are common mistakes. For swallowing or eyes, follow the label and use NHS 111 or the emergency services. White mineral oil is often an aspiration hazard under GB CLP. Food-grade wording does not cancel a swallow warning on the bottle. If you want tung oil compared on its own, see the tung oil comparison.
Our verdict
The top pick is Brandon Bespoke mineral oil, 500 ml, at about £11.95. It has the highest editorial score in this set, with 4.7 from 1,538 reviews, and the title names wood, slate and stone. It does not cure, and one UK review notes a swallow warning. The best value is Lubrisolve mineral oil, 2 litres, at about £16.99, about £8.50 a litre, the lowest price per litre among the mineral oils here. Use Osmo 620 on exterior absorbent stone, and do not treat honing oil or a nano spray as a worktop oil.
