Chem Dry rep gave us a free sample and liked it so much we ordered more.pked corectlyGreat Product but way overpriced. This product has always been high priced everywhere but gets the cat yack out of the carpet.It does a good job, it's expensive, and there may be some out there that does as good at a cheater price, I just don't know where!Excellent product....gets rid of hard the clean stains.Great stuff, but so far three cans have been duds ... full, but no fizz.
