Cleans WPC perfect to use terraces at various dilutions. Even grease stains from the last barbeque were (but undiluted as a rag, soak for about 10 minutes and rinse with plenty of water) on the terrace without much trouble to remove!
I am not an expert with respect to WPC-cleaning, but I do not see the effect of the special cleaner. Vielleich he cleans particularly gentle. Sauber makes the thing definitely in the broadest sense.
Price Leistungsvehältnis outstanding! Cleans and maintains excellent, easy to work, good lasting effect. For large terraces excellent and empfehlen.Empfehlung for all owners of a claimed Garden terrace.
