BIO-TECH TD is a liquid product for treating drain pipes and grease traps. It contains cultures of non-pathogenic and non-toxic bacteria specially adapted to quickly break down grease, oil and organic compounds. It remains active in drains below the grease trap and keeps drains from clogging. BIO-TECH TD lets you empty grease traps less often, cuts down odors and controls insects. It is biodegradable, safe for drains and environmentally friendly.
