If you have any doubts about which carpet cleaning company to use, just look to the carpet industry itself for clues as to which method is the best for your carpets and upholstery. There is a reason that almost every major carpet manufacturer recommends (and more increasingly requires for warranty reasons) that you use hot water extraction to maintain the cleanliness of your home carpeting. And there is also a reason that almost every major carpet cleaning company, from ProClean Carpets down the line, chooses hot water extraction as their method of choice.
ProClean Carpets use hot water extraction.
You can have your carpets cleaned,
Or you can have them ProCleaned!
