The Karcher EXTRA RM 31 ASF is a highly concentrated high pressure basic detergent. It comes in a 2.5 litre size. That suits smaller jobs and occasional use. It also helps when storage space is tight.
It is built for stubborn industrial soiling. It cuts through oil, fat, grease, tar, soot and smoke resin. Because it is concentrated a little goes a long way. It is active at all temperature ranges. That means cold water or hot.
The ASF property is the clever bit. The detergent rapidly separates oil and water in an oil separator. That keeps waste management on site simpler. The formula is free from phosphates, silicone and NTA. The tensides are biodegradable under EEC 648/2004.
A fresh fragrance makes it nicer to use. Karcher also sells it in a 20 litre size for heavy use. This is a professional pick for garages, workshops and cleaning firms running a pressure washer.
