MICRO-CLEAN GREEN deep cleans, removing embedded residual grease and organics especially in porous tile, cracks, crevices, and corners. MICRO-CLEAN GREEN continues to work when washed down the drain, digesting grease and organics as it flows through the pipes into the sewer or septic system where the bacteria continue to remediate fats, oils, greases and other organic matter. MICRO-CLEAN GREEN contains no chlorine, phosphates, or other potentially harmful chemicals, and is safe for humans, animals, and the environment when used as instructed.
