Since carpet fibers look cleaner immediately, before extraction takes place, people often ask us, "where did the dirt go?"
We answer by comparing CRYSTAL DRY® cleaning agent and its encapsulated soil particles with a diamond. Diamonds always have flaws from embedded foreign particles, but these flaws are not seen except under high magnification. Similarly, CRYSTAL DRY® cleaning agent entirely encapsulates foreign soils in a clear polymer that still looks perfect to the naked eye or even under low magnification. The soil is there, but all that can be seen is bright and clean carpet. The soil-laden crystals are removed easily by vacuuming, which may occur at any time without adverse effect.
