The dry cleaning methods - which are dry foam, dry chemicals, and dry compound - do not rinse your carpet in any way.

You might say they clean your carpet only halfway. The most effective cleaning method is hot water extraction as the primary method of cleaning carpets. Carpet cleaners use one of two types of hot water extraction. If they use a large unit that operates from a van or truck outside your facility, it's called truck-mount extraction. If they use a small unit that can be brought inside, it's called portable extraction. Shaw's first choice is the truck-mounted unit-and it recommends the small, portable unit only in areas where the truck-mounted unit won't reach.
