General rules for wool carpet

Wool is a protein fibre and behaves nothing like the synthetic carpet most stain advice is written for.

Alkaline cleaners, which is most general purpose carpet products, cause colour bleeding and damage the fibre. Chlorine bleach destroys it outright. Rubbing distorts the pile permanently, so every method is blot, never scrub. And over-wetting pushes the spill down into the backing where it wicks back up as a brown ring days later.

Check the label

Check whether the carpet is under a manufacturer warranty. Some are void if a non approved cleaning product is used, so a WoolSafe approved product protects the cover as well as the carpet.

Stains on wool carpet

Cleaners on wool carpet

  • White vinegar Yes, with a pre-test

    Wool prefers mild acid to alkali, and the UK carpet trade body method for coffee on carpet uses a detergent and vinegar solution. Keep it dilute, apply a little at a time and blot it back out.

Wool carpet is worth treating carefully because it is expensive and because most of the advice you will find online was written for synthetic carpet.

The three things that ruin it

High alkalinity, which covers a lot of general purpose cleaners, causes dye bleeding. Chlorine bleach dissolves the fibre. Scrubbing flattens and fuzzes the pile in a way that does not recover.

Why less water is better

Wool holds a lot of moisture. Soak a spot and the liquid travels into the backing and the underlay, then wicks back to the surface as it dries and leaves a ring larger than the original mark.
