What it is
Kärcher VehiclePro Hot Wax Classic RM 820 hot wax, in a 20-litre canister. It is not a wax to apply by hand: it is a concentrate from the Classic line for car wash installations, which Kärcher lists among the recommended detergents for gantry washers such as the CW 1 Klean!Fit. It has a pH of 4, so it is mildly acidic; the contents weigh 19.8 kg.
What it is for
Used for washing surfaces and equipment, for vehicle maintenance, in the workshop and on the road and for cleaning vehicles, inside and out.
How to use it
Wash the bodywork and interior in the shade, on surfaces that are not hot, using the cleaner at the stated dilution. Apply waxes and protectants to a clean, dry surface and buff with a microfibre cloth. Always read the instructions for chemical products, keep them away from eyes and skin, and close the containers after use.
