Positive 170 is a unique heavy-duty cleaner for use in spray cabinets or "Proceco" cleaning tanks. It is a non-foaming liquid cleaner that removes grease, oil, paint, and rust from ferrous equipment. The extra-long tank life will amaze you; there is no other product like Positive 170 on the market. The only thing coming out of your washer will be clean parts. Positive 170 also works to remove dried-on wood pitch and glues from saw blades and heads. This product is available in 6-gallon pails and 55-gallon drums. Contact us for price and freight quote, as Positive 170 must be ship by truck freight.
