We have the appropriate minerals and cleaner to remove efflorescence, a white haze that can leach out to the surface of your pavers from minerals in the concrete mixture. And we can typically remove most oil and grease stains from BBQs, food, and automotive oil drippings. And moss and mold growth is no problem for our surface cleaner. We use a hot steam pressure cleaner with water temps around 250 degrees, and water pressure psi adjustable to upwards of 450 psi.  Our years of experience using the right combination of cleaners, steam, and water pressure will typically remove almost any stubborn stains on your paver, natural stone, and concrete surfaces.
