Carpet Steam cleaning Greyson way Milpitas Ca California

Carpet Steam cleaning Greyson way Milpitas Ca California. These stairs were noticeably dirty/greasy. The stairs required Degreaser which I charge extra for, because I have to pay for the degreaser...not cheap stuff. Whenever I get a call that involves stairs, I already know it is noticeably dirty, unless you tell me otherwise, or have new carpet less than maybe 6 months old and it has been walked on by regular use, In fact the same is true for any carpet next to a hard surface. Why? Grease, dirt shoes wearing off on carpet.
