Top pick for a small painted job
For doors, skirtings and isolated marks, the Bartoline ready-to-use spray, pack of two, is the convenient pick. It was about £5.36 for two 500 ml bottles. It needs no measuring, and it tells you to spray, wipe and rinse from the bottom upwards. A larger grease splash still needed scrubbing.
Convenience is the reason, not a stronger mix. A reviewer called the ready-made liquid too weak for many jobs. The listing does not name nicotine, and someone who bought it for limescale was unimpressed. At about £5.36 per litre applied, you pay for not mixing a bucket.
The four-bottle version is the same model 104662148, the same directions and the same parent count of 2,089. At about £10.72 it is twice the bottles at twice the price. Buy four only if you will use two litres.
Best value when you will mix a bucket
For a room-sized wash, the 500 ml Bartoline concentrate is the lowest shelf price in this snapshot, about £4.34, with 4.5 from 2,520 ratings. The manufacturer field names Tetrosyl Express Limited. Reviewers described kitchen grease, wallpaper adhesive and nicotine film.
The bullets say dilute, scrub, rinse and dry, and they do not print the quantity. Bartoline's sheet gives about 125 ml in 4.5 litres for paint preparation. On that instruction the shelf price is about £0.24 per mixed litre, which is label arithmetic, not a coverage test. One reviewer said the bottle lacked markings, and another called the liquid a little abrasive.
This concentrate is the top pick and the cheapest shelf price, so the best value sits on the next own listing, the powder. The format trade-off is in sugar soap powder vs liquid.
When the powder is the one to open
Choose the Bartoline powder when the ratios on the listing matter more than the lowest shelf price. The bullets specify 500 g in 10 litres of warm water for paint preparation and 250 g in 10 litres for general cleaning, then a rinse and a dry.
At about £8.54, that paint-prep mix is about £0.85 per mixed litre if 500 g produces 10 litres. That is label arithmetic, not measured coverage. The title says 500 g and the weight field says 450 g. Reviewers used it on kitchen doors and more than one bucket. One found powder messier than ready-made liquid.
Powder is not automatically stronger than concentrate. A single door does not need a bucket. The pack directions are in how to use sugar soap.
Listings not to crown without checking
The three-flask row at about £5.62 showed 4.7 from 578, but the title used Bartoline while the manufacturer field said SEVENMEET. It claimed three 500 ml flasks beside a 100 g weight. With no ratio and no rinse, the star line does not make it a Bartoline substitute.
ZYBUX at about £9.95 specifies each 500 ml bottle for 4.5 litres. That is a different instruction from the Bartoline sheet, not evidence of better cleaning. Mangers powder showed 4.5 from 335 and still had no usable dilution on the captured page.
Heavy tar or widespread fire soot sits outside any responsible pick. Decide first whether the wall should be washed in sugar soap before painting. Extensive soot or recurring damp needs a professional.
Common questions
Which sugar soap is the top pick for one room?
The Bartoline concentrate at about £4.34 is the top pick for a bucket wash in this set, if you take the ratio from Bartoline's technical instruction. The Amazon bullets omit it. If you want the mix printed on the listing, the Bartoline powder at about £8.54 is the easier pack to follow. The powder also carries the best-value badge, because the concentrate is already the lowest shelf price.
Which option is best for doors and skirtings?
The Bartoline two-bottle spray suits a small painted job because it needs no measuring and it tells you to wipe and rinse. It is dear per litre of liquid applied, and a reviewer called the ready-made mix too weak for a large greasy area. Its advantage is the door and the spot mark, not a whole kitchen.
Is the four-pack spray stronger?
Nothing on the listing suggests that. The two- and four-bottle products share model 104662148, the same instructions and the same parent reviews. The four-pack doubles the volume. At the captured prices it also doubled the cost, from about £5.36 to about £10.72.
Is the three-pack really Bartoline?
The captured title included Bartoline. The brand field was Sugar Soap and the manufacturer was SEVENMEET. The weight and the dimensions also cannot be three 500 ml flasks. Check the current seller and the packaging rather than describing the row as Bartoline factory stock.
Will sugar soap remove nicotine before painting?
The Bartoline concentrate title and the powder information name nicotine, and reviewers describe washing smoker-stained walls. That supports a wash for surface film. It does not prove that years of tar will lift, or that the next coat will block staining. Rinse, dry and look at the wall before you paint.
Why is the concentrate cheaper than the powder?
Those were the amazon.co.uk shelf prices on 15 October 2026, not a rule about manufacturing cost or cleaning power. Pack format, seller and marketplace pricing all differ. Compare the dilution you can actually follow, and the manufacturer field, rather than assuming a higher shelf price means a stronger cleaner.
