Pro Carpet Cleaning: Chemdry vs Steamer vs ??
Looking for a carpet cleaning service that does a good job, doesn't use harmful chemicals, etc. Any help/input appreciated.
Carbonated/Buffer (Chem-Dry): Often accused of 'fear marketing'. Their traditional method supposedly doesn't really extract the dirt from the carpet/house and their buffers wear carpet down. Many complaints that carpet is extremely stiff after cleaning. They have apparently begun switching to a truck based extraction system (hot water extraction, but 'carbonated'?) that may work better. But can they be trusted?
Hot water extraction (Stanley Steamer, COIT, etc.): Perhaps best for extracting dirt. Numerous concerns that if not done properly that high amount of moisture left in carpet & pad can cause mold/mildew growth and faster deterioration of backing and pad. Some/many do use perc, hydrogen peroxide, and other not too appealing chemicals?
Other options? Independent cleaners better than franchise chains such as the 3 above? Any websites with an honest comparison of methods and who provides them?
