This product is the result of exhaustive research and testing that surpasses any petroleum industry cleaner and degreaser. WASH N WAX HD is a water soluble, biodegradable, non-flammable, non-toxic concentrate and may be used in pennies-per-gallon dilutions to out-perform other cleaners. It is pleasantly scented, stainless and leaves no oily film or residual gumminess. WASH N WAX HD is safe to use on metals, electrical insulations and most painted and plastic surfaces. It will pay for itself in its virtually unlimited applications by replacing many obsolete degreasers with one all purpose concentrate.
