Steam greatly reduces exterior wash time. The traditional method of car washing is a five step process (pre-rinse, soap, rinse, dry and wax). Using steam, there are only two steps. Step one, the operator sprays the vehicle’s surface with steam and then dries the surface with a microfiber towel. Step two, the operator applies a surface protectant. Use steam to avoid damp interiors. Steam is a light, super-heated, vapor. Steam penetrates dirt quickly, kills bacteria and removes odors. With dry vapor-steam, upholstery dries in minutes, not hours.
