Efflo Off is a technologically advanced concentrated blend of buffered, non-acid organic salts and additives designed for the removal of tough efflorescence, mineral and salt deposits without damaging the surface when following dilution instructions. Its biodegradable, environmentally friendly and phosphate-free formula safely replaces many harsh acid-based cleaners. After spot cleaning has been completed, Efflo Off can be used outside, on old and new, horizontal or vertical surfaces as a heavy duty surface cleaner and will prepare the surface for sealing by creating optimal conditions for sealer adhesion and ultimate aesthetic value. Efflo Off’s Clean Rinse Technology allows dirt and cleaner residue to be quickly and easily rinsed away with a low or high pressure washer. Efflo Off is concentrated and requires dilution prior to use. With proper dilution and dwell time, it is safe to use on surfaces sealed with Surebond sealers.
