For cleaning buses, trucks, haulers, trailers, heavy equipment cars and all rolling stocks from grease, oil, waxes, road film and most soils. Very efficient for pre-soaking at winter time. Strongly alkaline foaming soaking and prewash agent with rust inhibitors. Complexing agents in solution ensure good washing results even with hard water. Can be used as foam shampoo. Due to its foamy consistency the cleaner also works very effectively on vertical surfaces and does not damage paintwork when using brushes or sponges.
