Remove dirt from the vehicle with a powerful water jet. Dilute 2 capfuls of the shampoo in 10 litres of warm water and foam up. Wash partial area of the vehicle (e. g. roof, bonnet, etc.) with SONAX Multisponge. Afterwards, immediately rinse vehicle with a lot of clear water to remove shampoo and dirt residues. Then, wash next partial area. After the wash, empty and rinse bucket. Dilute 1/2 a capful of the shampoo in 10 litres of cold water. Do not work into a lather. Starting with the roof and then working from top to bottom, pour the solution extensively over the vehicle. Depending on the size of the vehicle, you may need another bucket. The water film slowly runs off and dissipates. The vehicle simply dries by itself - no drying required!
PLEASE NOTE: Do not use on hot surfaces, do not allow to dry. Protect against frost.
