Natural CompleteĀ is a unique microbial product. While providing superior metabolic activity (waste degradation), the microbes in Xtreme MIC are sheathed to protect them from chlorine, sanitizers and heat; which easily kill most other microbe based products. This is a distinct advantage when used in drain line maintenance. Quickly degrades petroleum hydrocarbons, vegetable and animal fats, oils, greases, waste solids and other organic compounds.
