RX 32 is not an acid or caustic. Works nature"s safer way, but faster. With Airicide and an additive for immediate action. RX 32 is a unique environmentally friendly bio-enzymatic formulation that replaces the hazardous products needed in the past to open clogged and sluggish drains and traps. It has been specially formulated to attack the grease and fats that are the usual cause of blockages in kitchens and the body oils and soap film that build up to clog drains and lines in showers and bathroom sinks. Bio-enzymatic action has been nature's way of degrading waste since the beginning of life, but until now, enzymes did not act fast enough to solve an emergency drain problem. Now with advanced chemistry, this proprietary formulation acts immediately to break up fatty, greasy blockages.
