The product information also specifies VDA Class A usage conditions of a maximum contact time of 5 minutes and a maximum application concentration of 1:100. Do not use in direct sunlight or on hot surfaces, to avoid rapid drying that may leave marks.

Use neat or diluted to 1:10 with a dosing pump. Recommended dosage per vehicle: foam and self-service systems 3-8 ml; car shampoo 1-3 ml; hand washing dilution ratio 1:300. Pre-dilution may be necessary due to the product's high viscosity and the lower delivery rate of dosing pumps.
