I was looking for a "dry" cleaning system that was not loaded with chemicals. I have used chem-dry in the past and the stains that I have previously removed with woolite carpet cleaner always came back within a 2-wk time frame of having them professionally treated. It has been almost 3 weeks and those reoccurring spots have not reappeared! The carpets did not have a chemical scent either! I am very satisfied & I have recommended "dry carpet" to all my friends.
