GAF 5 Gal. Cleaning Concentrate Cleaner

Cleaning Concentrate is a highly effective cleaning agent and de-greaser. It was specially developed for the proper cleaning of existing elastomeric coating on roofs, metal surfaces and concrete and masonry substrates, as well as uncoated roof, deck and wall surfaces. It penetrates the old coating, lifting the oxidized material, dirt, grease and other contaminants into suspension for easy flushing from the substrate, leaving behind an acceptable surface for re-coating.
