Karcher RM 838 VehiclePro Foam Cleaner Detergent 20L

The Karcher RM 838 VehiclePro Foam Cleaner Detergent is an alkaline foam for contactless washing. It comes in a 20 litre container. Karcher Pro makes it for professional vehicle cleaning.

It cuts through heavy oil, grease, insect residues and road dirt. The alkaline formula breaks down stubborn dirt on contact. You do not need to touch the vehicle. That suits fleet maintenance and commercial vehicle washing.

Paintwork is the worry with brushes and cloths. A contactless wash reduces the risk of surface abrasion. Karcher says the foam is gentle on paintwork while it tackles heavy contamination.

The 20 litre size is made for high volume washing. Valeting firms and fleet depots will get through it steadily. A home car owner would find it far too big.

The pack is a 20 litre container. Karcher Pro backs the range with its professional warranty. That cover is for manufacturing defects. It does not cover wear or misuse. Follow the label for dosing so a drum lasts longer.

An alkaline cleaner breaks down oily and organic dirt chemically. That is why it can work without scrubbing. Applied as a foam it clings to the vehicle so it has time to act. You then rinse the loosened dirt away. In real use this means less contact with the paint. That lowers the risk of scratches from dragging grit across it.

Wear gloves and eye protection when you handle an alkaline cleaner. Follow the label dose. Rinse the vehicle fully and do not let foam dry on the paint. Do not mix it with other chemicals. Store the drum closed and away from children.
