Rug Materials to Avoid Using Carpet Cleaner On Wool is a strong natural fiber, but that does not mean it can be cleaned with a carpet cleaner. When they're cleaned with hot or warm water, the water can cause the natural dyes of the rug to run and ruin the rug's beautiful pattern.

Mix 1 teaspoon (4.9 ml) of wool detergent, 1 teaspoon (4.9 ml) of white vinegar, and 4.25 cups (1L) of warm water. Dampen a cloth in the solution, lightly rub and dab the stain. Now use a damp sponge to remove the cleaner. Blot all water up with a dry paper towel and let the area dry for several hours.

It's important to remember to blot rather than scrub – scrubbing will push the stain further into the pile and damage the fibres. Use water or a WoolSafe approved cleaning spray (which is colour, fibre and re-soiling safe) to complete removal of the spill. Spray this onto the cloth first, and then dab the spill.

Wool is a high quality material, but it is also too delicate to stand up to the pressure from a power washer. In order to clean stains out of a wool rug or clean it as a whole, read the tag's care instructions and consider reading specific guides for your primary issue, such as a guide on getting dog pee out of rugs.
