What is the most effective way to clean wool pile rugs? I use our standard system, groom, vacuum(usually several times) spray with 101, groom and then buff with regular pad followed by woven turf. I always feel like I am not getting them clean enough, I get frustrated with the patterns I seem to leave, even after grooming. Please let me know a more effective way, I leave alot of money out there because I am worried I am not cleaning it as well as other companies may.
