Best graphite powder for locks

Updated: 23 October 2026

You want one bottle for a stiff front-door cylinder, and the search results mix lock puffs with drawing tins and a 5.0 from two ratings. The best graphite powder for locks, inside this amazon.co.uk set, is a review-volume call with a price call beside it, not a lab test. Both calls fail if your cylinder maker names a different product or bans graphite. The full grid is the [graphite powder comparison](/hub/diy-supplies/graphite-powder).

What best means here

Best on this page means the highest score after stars, review count, listing conflicts and UK review faults are marked. A 5.0 from two or three ratings cannot win that sum. Kasp scores 88. Cretacolor, a drawing tin, scores 87 and is not a lock pick. Lution scores 85. Pressol scores 77 and takes the value award on price, not on the top score. It is not a locksmith trial.

Top pick, Kasp K30050 pack of 2

Kasp is the top pick when you have an ordinary door lock or padlock and the leaflet allows a dry graphite puff. The listing says greaseless and odourless, with a fine dispensing spout. The 50 UK texts describe sticky Yale nightlatches, Abus padlocks, car locks and a motorbike ignition freeing after a light puff. A small dose is the pattern. A heavy squeeze marks the door and your hands. The title says a pack of 2. The included-components line says 1 x K30050. A liquid-volume field says 0.3 litres, and no mesh is printed. UK texts repeat an open cap and a tip that clogs. How much to use, once the leaflet allows it, is on how to use graphite powder on a lock.

Best value, Pressol 50 g

Pressol is the best value when you want a low price and a large sample, and you have read the conflicting lines. The title says natural graphite, 50 g, grease-free, at about £5.17. The UK texts are mostly door locks and padlocks, and several say a water-displacing spray had already made the lock worse. The attribute block says item form paste and SAE J300 0W-20. A liquid-volume line says 100 ml. The title is the grease-free claim. The attribute block is a contradiction left in the capture. If you need a listing that does not say paste, choose Kasp or the Ultion-named bottle. No particle size is printed.

When the branded tube is the one to buy

Buy the Lution XM bottle, about £11.80, when the lock is an Ultion. The bullets call it the Ultion-approved micro graphite, 50 g, and they say there is no need for oils or WD-40. They also say a well installed lock needs lubricating every six months. The spout blocks in those texts. The number-of-items line says 50, which is not one 50 g bottle. Micro is not a mesh number. Skip both the top pick and the best value if the cylinder is APECS. APECS says not to use graphite and not to use WD-40, and it names APECS dry lube. The split between brands is on graphite powder vs WD-40.

Who should skip the 5.0 scores

LUNAULTRA is about £6.99, 5.0 from two UK reviews, a 60 ml bottle with a precision nozzle and an item weight of 14 g. Two reviews are too few to treat silence as a clean record. LINKKNOB is about £5.19, 5.0 from three ratings, with one UK sentence that calls it a good product for locks. Material and mesh are blank, and the part field is the string cweacew472. Artist tins are the wrong tool for a keyway. Cretacolor's UK texts are drawing, not locks. The Koh-I-Noor pair share one GTIN.

Common questions

Which powder has the most UK ratings in this set?
Kasp K30050, ASIN B0HGBMWL8Q, shows 4.7 from 5,371 amazon.co.uk reviews in this capture, the largest count of the ten kept listings. Fifty of the stored texts are marked United Kingdom. Cretacolor has 2,439 and Pressol has 2,168. The 5.0 bottles have two and three ratings. The top pick uses that Kasp count together with the greaseless lock wording, not the star line alone.
Is the £5 Pressol as good as Kasp?
Pressol has more conflicting lines and a slightly lower star average, 4.6 from 2,168 against 4.7 from 5,371. It is about £5.17 against about £10.70 for the Kasp pack. UK reviews of both are about sticky locks, often after a water-displacing spray. Pressol is the best value if you accept the paste and SAE attribute block. Kasp is the top pick if you want the larger sample and a title that does not also say paste. Neither is a lab winner.
Do I need the Ultion tube if I do not own an Ultion lock?
No. Lution XM is the bottle to buy when the lock is an Ultion, because the bullets and the maker's page name that graphite. For another brand that simply allows dry graphite, Kasp or Pressol are the large-sample choices here. For APECS, you need APECS dry lube, not any of these three. A six-month interval on the Lution bullets is that listing's instruction, not a rule for every cylinder in the UK.
Why not the 5.0 bottles?
LUNAULTRA has two reviews and LINKKNOB has three ratings. A 5.0 on that sample is arithmetically perfect and statistically thin. The scoring method gives those listings a small sample mark, so they finish at 70 and 64, under Pressol at 77 and Kasp at 88. Their nozzles may be fine. This page will not call them the top pick until the review count is in the same league as the bottles they sit next to.
Is the Kasp listing one tin or two?
The title says pack of 2, and the number-of-items line says 2. The included-components line says 1 x K30050. Unit count is 100 g, item weight is 106 g, and a liquid-volume field says 0.3 litres. The capture keeps all of those lines. When the parcel arrives, count the containers. Do not assume the included line and the title describe the same quantity.
