KD-440 Concrete Cleaner

98037440 KD-440 is a non-caustic, butyl-based blend of ingredients formulated for cleaning of stone and concrete surfaces. This popular cleaner is effective in removing grime from concrete but safe enough not to damage painted surfaces. It is effective in removing oil, grease, baked-on carbon, tar and asphalt from floors, walls and stainless steel. As with other Kärcher detergents, KD-440 is engineered to pass through a pressure washer without damaging the high-pressure pump. Furthermore, it is biodegradable and safe to use on aluminum, stainless steel, glass, plastic, paint and fine automotive finishes.
