This video shows how a typical dry carpet cleaning is performed. It always starts with a particulate powder that is distributed onto the carpet and brushed in. This particular company calls their dry carpet cleaning product granules. Every time I have seen this done I think about our cleaning process at Chem-Dry of Tampa FL. We don''t use dry carpet cleaning powders or granules, mainly because there is always a bunch of the cleaner left in the carpet.
Let me be clear, all carpet cleaning processes leave something behind in the carpet. Even if the carpet was only cleaned with hot water there is water left behind on the carpet because there are no vacuums powerful enough to remove all the water in the carpet. but water does eventually evaporate. When dry carpet cleaning with a power or granules there is going to be particulate matter left behind in the carpet.At least 12 to 20% of the original carpet cleaner will still be in the bottom of the carpet fibers depending on the power of the vacuum.
I can always tell when one of these dry carpet cleaning has been performed on a carpet I'm cleaning. The accompanying picture shows all the cleaning powder stuck to my equipment after I clean a dry cleaned carpet. I think to myself every time "If this home owner new what was being left in their carpet by one of these dry carpet cleaning systems they would never have it done.
At Chem-Dry of Tampa FL our low moisture steam cleaning uses a hot carbonated solution that removes deep soils from the bottom of your carpet while removing 95% of the moisture that is applied. This means your carpet dries really fast with now dirt attracting residues left behind.
