I've been in the carpet cleaning business for only a few months and I've had several requests to clean wool area rugs. I actually turned down a job because I wasn't sure which detergent to buy and was nervous about bleeding and discoloration occurring during cleaning. I'm just curious if anyone with more experience might be able to provide some insight as to which detergents are best for wool. I know that the pH level should be low and that there are products with "woolsafe" seals but I figured that it would be smart to get some advice based on first hand experience before purchasing a new chemical.
