Enviro Klean SafEtch is an effective, safe alternative to acidic compounds for cleaning and preparing textured concrete surfaces for clear or pigmented coatings. SafEtch rids textured concrete of excess mortar, embedded oil, grease, efflorescence and dirt. It's ideal for projects where traditional acidic cleaners are not allowed.
Non-fuming SafEtch contains no hydrochloric or other traditional inorganic acids and is safe for use on and around most metal surfaces. Additionally, it is up to 70 percent more effective than citric and glycolic acids, and 50 percent more effective than phosphoric acid.
