2. Carbonated Cleaning
The carbonated cleaning method, used by such companies as Chem-Dry, had a lower percentage of soil removal than the the circular dry foam method ( 77.7 % ). The carpets weren’t soaked thru to the padding (as in methods # 5 thru # 11 ). THis is good because it avoids rippling (little lumps in the carpet ) or other forms of carpet damage such as faded coloring, separation of carpet from backing by hot water being shot thru @ high speed or padding deterioration. The floors underneath showed no sign of mold or mildew fungus.
Carpets re-soiled in average of 9 months.
