We have used 1-800-DRYCARPET for at least 5 years. Our carpets are cleaned far less frequently than our neighbors because their old spots keep reappearing.

We have a big husky {DOG} who must run thru every possible dirty place when I walk her. When a spot appears, I use the little squirt bottle http://www.drycarpet.com/preferred_stain_clean.htm of miracle cleaner and it is gone.
