Unfortunately, a lot of “off-the-shelf” carpet cleaning products contain alkaline products like ammonia. You should never use ammonia or any other highly alkaline carpet cleaner on a wool rug as it can cause damage. Home cleaning for rugs is really not recommended as wool fibres absorb more water than synthetic fibres.

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.

Rubbing alcohol is a great way to clean your carpets without leaving behind any residue. As it evaporates quickly, it won't soak into the fibres of your carpet, which can potentially cause more trouble than the original stain!
