Attacks all soils commonly found in carpeting. Its unique formula emulsifies them, and then using the latest technology, encapsulates the soil for easy removal. Because the soil is encapsulated, whatever does not come out during extraction will be removed in subsequent dry vacuuming. It can even eliminate the need for re-extraction when wicking (capillary action) occurs in heavily soiled carpets. pH-iber™ Guard Extraction Carpet Cleaner will not remove the stain resistant properties manufactured in to the carpet and will actually replenish them. As a bonus, this product eliminates the need for a defoamer, even on carpeting with residue previous shampoos.
