Leather: what it can take

Covers finished (protected) leather sofas, jackets, bags and car seats. Use as little liquid as possible on leather: blot and dab rather than pour, because whatever soaks in cannot be rinsed out properly.

01 What it is

Finished leather has a protective topcoat over a tanned hide; anything that strips the coat or the oils marks it.

Leather cannot be rinsed through, so whatever you put on it partly stays in it.

02 House rules

  • Use as little liquid as possible on leather: blot and dab rather than pour, because whatever soaks in cannot be rinsed out properly.
  • No rubbing at all; every step is a press-and-lift.
  • No soaking, so each treatment is applied, given a few minutes, and blotted away.
  • Water stays at or below 30 °C (86 °F) the whole way through.

03 Field notes

  • Most sofas and car seats use finished leather with a pigmented topcoat, so stains sit on the surface for a while. Aniline leather soaks them up instantly.
  • Oil darkens leather by soaking in, and powder can draw it back out if you give it hours, not minutes.
  • Cleaners and conditioners must be suitable for the exact leather and finish. Conditioning is not automatically required after every clean.

06 The most common mistakes on leather

Counted across all 41 stain files for leather:

  • The dryer before it is gone (33 files). Dryer heat locks in whatever is left. Air-dry and check first.
  • Hot water (24 files). Hot water helps the colour bond, and leftover sugar browns later under an iron or in a dryer.
  • Rubbing or scrubbing (22 files). It spreads the stain and grinds it deeper; blot instead.
  • Oxygen bleach (OxiClean-type powder) (15 files). Oxygen bleach strips and blotches leather dye and finish.
  • Bar soap or soap flakes (6 files). True soap is alkaline, and alkalis set tannin stains such as wine, coffee, tea and fruit.
  • Water first (3 files). Water spreads alcohol-based ink and does not dissolve it.

07 What the leather files use most

These are the products the 41 stain files for leather rely on most. Dish soap leads because surfactants have a water-loving end and an oil-loving end.

08 When to call a professional

Aniline (unfinished) leather, antiques, designer bags and any stain that has changed the colour of the leather itself.

Specialist-rated stains on leather: BBQ sauce, mildew, nail polish, permanent marker, self-tanner, super glue and turmeric.
