In detail
Solvent wiping uses a volatile organic solvent — methylated spirit, isopropyl alcohol or acetone are the ones named in trade guidance for metal — to dissolve oily residues and then evaporate, taking nothing away with it and leaving nothing behind. Its advantage over detergent is entirely about the aftermath rather than the cleaning: there is no rinse step, no water and therefore no drying mark, which is why it is the standard treatment for fingerprints and grease marks on vertical stainless panels and for anything where water is unwelcome. The limitations follow from the same property. A solvent dissolves what it can reach, and that includes paints, varnishes, some plastics and the coatings applied to display screens, so a technique that is correct on bare metal is destructive a few centimetres away on a painted panel. These solvents are flammable, their vapour is heavier than air, and they require ventilation and distance from ignition sources rather than casual use. And hypochlorite bleach reacts with alcohols to form chloroform, so a surface that has had bleach on it must be rinsed before a solvent goes near it.
What works
Solvent wiping is effective against Fingerprints Supported
Solvent wiping is effective against Grease Supported
Solvent wiping is effective against Grease Strongly supported
For wool specifically, the trade body sequences solvent BEFORE water and requires full evaporation between.
Solvent wiping is effective against Grease Supported
On wool the ORDER is the instruction: solvent first, allowed to evaporate, and only then anything water-based.
Solvent wiping is safe on, in specific conditions, Stainless steel
Safe only in specific conditions
This is only appropriate within specific limits. Outside those limits, no claim is made.
Only within these limits:
- Methylated spirit, isopropyl alcohol or acetone
- Ventilate, and keep away from ignition sources — these solvents are flammable
- Never on a surface that has had bleach on it without rinsing first
Hypochlorite reacts with alcohols to form chloroform, so the sequence matters as much as the choice of product.
Precautions
- Ventilate the area
- Never mix with other cleaning products
- Rinse thoroughly afterwards

Solvent wiping is safe on, in specific conditions, Finished wood flooring
Safe only in specific conditions
This is only appropriate within specific limits. Outside those limits, no claim is made.
Only within these limits:
- Preceded by removal of loose soil with a soft cotton cloth or a vacuum with a soft brush attachment
- Preceded by a solubility test on an inconspicuous area
- A soft bristle brush dipped in the solvent for carvings and intricate work
- Where the finish is worn or cracked, use the solvent rather than water
Cleaning beyond dusting is performed only as needed rather than on a routine schedule, which is part of the instruction rather than a preamble to it.
Precautions
- Test on an inconspicuous area first
- Ventilate the area

Solvent wiping is safe on, in specific conditions, Finished leather
Safe only in specific conditions
This is only appropriate within specific limits. Outside those limits, no claim is made.
Only within these limits:
- Only after dry brushing has taken off what it can
- Cotton swabs dampened with ethanol or odourless mineral spirits — damp, not wet
- Test first: the source states plainly that this may damage some leathers
- Expect reduction, not removal, and expect it to return
The expectation is part of the clearance. A reader told only that solvent works will scrub until the finish goes; the source says the deposit 'can never be removed fully and safely' and that saves the object.
Precautions
- Test on an inconspicuous area first
- Ventilate the area
- Wear gloves

Why
- Solvent wiping is explained by Surfactancy
By contrast rather than by application: a solvent dissolves the oil outright, where a surfactant only makes it transportable in water.
Aftercare and prevention
- Solvent wiping requires the aftercare Wool
The aftercare is a wait: the solvent must fully evaporate before any water-based treatment follows.
- Solvent wiping requires the aftercare Finished leather
Deep cleaning and conditioning is described as necessary every four to six months, and over-applying cleaner leaves a tacky surface that transfers to clothing.
- Solvent wiping requires the aftercare Finished wood flooring
Rewax once the wood has dried completely. The cleaning removes the protective wax coating, so stopping at the clean leaves the surface less protected than before it was touched.
When the obvious answer is wrong
How do I get a grease mark off suede without ruining the nap?
Suede is the porous lower split of the hide with nap on both sides, dyed like aniline and uncoated. The trade guide states that cleaning agents will immediately darken nude leather — there is no cautious first application, because the first application is the result. Water is not a safe alternative either: the guide specifies deionised water because hard water containing minerals may cause rings. And the guide separately prohibits alcohol, strong solvents, high-pH cleaners and dish detergent on leather generally, as incompatible with modern finishes.
A different kind of treatment works: Change the mechanism from dissolving to absorbing. The trade guide's instruction is to place cornstarch directly over the affected area and rub gently with a finger until it coagulates with the oil, repeating as necessary. The powder offers a finer, drier pore network than the suede, so the oil moves upward into it and leaves with it — nothing is dissolved and nothing is carried deeper. Only if the mark is still evident after that is a cloth dampened with odourless mineral spirits used, and it is the last step rather than the first. Where water is unavoidable for a water-based soil, the guide specifies dampening rather than soaking a cloth and feathering the edges outward so no boundary forms, using deionised water so no mineral ring is left behind.
What should I use on red wine spilled on a wool carpet or jumper?
Wool is a protein fibre and oxidising bleaches attack it directly, degrading the keratin rather than the stain sitting on it. The damage is structural and it is not a mark that can be cleaned off afterwards: the fibre is weakened, and on a carpet the affected area wears differently from everything around it. The wool body approaches this from the other side, warning that methods aimed primarily at cotton or synthetic garments are not all suitable for wool.
A different kind of treatment works: Change the mechanism from oxidation to dilution and dissolution, and respect the order. The wool body gives red wine, fruit and fruit juice their own entry and its sequence is three steps. First RINSE WITH CLEAN WATER — before any product, because wine is water-soluble while it is fresh and the cheapest removal happens then. Second, a DILUTE solution of an approved wool detergent. Third, and only where the mark persists, THREE PARTS SURGICAL SPIRIT TO ONE PART COLD WATER. Technique carries the rest and is stated for every entry on the page: scoop or blot the excess immediately with white tissue or an absorbent towel, work from the EDGE towards the centre, and dab rather than rub. Finish with a wash in an approved wool detergent. Where the label permits dry cleaning and the mark survives, tell the cleaner what the stain is AND what has already been applied to it — a treated stain is a different problem from an untreated one.
What should I use on a greasy mark on a wool jumper?
Wool is a protein fibre, and the mechanism that converts fat to soap also hydrolyses protein. A strong alkali therefore attacks the garment on the same chemistry it uses on the stain, and the damage is to the fibre rather than to its appearance — it is not a mark that can be cleaned off afterwards. The wool body approaches the same problem from the other end, warning that methods primarily aimed at garments made from cotton or synthetic fibres are not all suitable for wool, and specifying a dilute wool detergent in TEPID water rather than anything stronger or hotter.
A different kind of treatment works: Change the mechanism from saponification to dissolution, and respect the order. The wool body's instruction for oily or greasy stains is that they are best treated with SOLVENTS FIRST, and that the solvent MUST BE ALLOWED TO EVAPORATE before any water-based treatment is subsequently carried out. That waiting step is the part most likely to be skipped and it is stated explicitly. The water-based stage that follows is a dilute solution of an approved wool detergent in tepid water — dilute rather than strong, tepid rather than hot. Technique carries the rest: scoop or blot the excess quickly with white tissue or an absorbent towel, work from the edge of the mark towards the centre, and do not rub. Where the mark survives that, the honest next step is professional cleaning rather than a stronger alkali.
How do I get a greasy mark off a leather sofa arm?
The leather trade body prohibits both by name, and the reason is the finish rather than the hide. Modern leather finishes are WATER-BASED, and its banned list is built around what attacks them: any high pH cleaner, cleaners containing alcohol, strong solvents, and caustic household cleaners such as soap or dish detergent. The stated consequence is cracking or other damage to the surface. It is the same reason saddle soap and mink oil are on the list beside glass cleaner - traditional leather remedies formulated for finishes no longer used.
A different kind of treatment works: Take the dry route first, which is the trade body's own procedure and reverses the direction the oil travelled. Place CORNSTARCH over the mark and rub it gently with a finger until it coagulates with the oil, repeating as necessary. Only when the absorbent has taken what it can does anything wet follow, and then it is a cloth dampened with odourless mineral spirits rather than a household cleaner. Technique carries as much of this as product. Cleaner goes onto a clean white cotton rag and NEVER onto the leather or into a spray. Work in a circular motion under moderate pressure, and the guide gives a memorable ceiling for that pressure: no more force than a firm handshake, because scrubbing damages the leather and makes the stain harder to remove. Air dry, with no heat. Two further limits are worth knowing before starting. Deionised water is specified where water is used at all, because minerals in hard water leave rings.
