After years of trying products to solve the problems related to cleaning commercial carpets, I have found encapsulation cleaning solves the problem of re-appearing stains and dry times are less than an hour. Encapsulation cleaning keeps carpet from re-soiling better than other methods I have tried.

Removing wax coatings on VCT tile with water only.
No strong smelling chemical needed when using weight and high speed oscillation. Low moisture cleaning means less time needed and Nano finish products reduce time to do job and a long lasting finish.
