Use any good quality, clean pressure sprayer, either electric or hand-operated. Stainless steel or plastic tanks are recommended to prevent rusting or staining. Use a #8004 Tee Jet nozzle. Spray pressure should not exceed 60 psi (do not aerosolize or atomize). Teflon™ carpet protector is also available for in-line sprayers like the Hydro-force* Revolution*. For the Hydro-force the truckmount should be set at 300 psi and use a #8006 Tee Jet nozzle.
