Resists resoiling, there is nothing in Jetclean to create a sticky film. It dries to small, transparent crystals with the dirt encapsulated inside. These no-stick crystals dry to non-stick powder that is easily removed by later routine vacuuming. Fast and easy to use, Jetclean is ready-to-use. One merely sprays it on to dampen only the soiled ends of the carpet pile and they brush it in. There's no need for complicated extraction machines, no need for defoamers, etc. Nylon certified, Meets chemical specification for use on lates generation nylon, so as not to affect factory treatment for resistance.
