After reading the Wheel cleaner tests a major car magazine I bought after a long time again / this brand product, instead of the no-names from the discounters. The application was great: Rim spray and wait until the cleaners purple discolored, rinse-ready. I sprayed the rims around my car, which as it were sufficient exposure-perfect timing. The only drawback was the sluggishness of the pump lever of the original bottle of Nigrin (750ml). Here I will probably use in the future my Compression Sprayer, which is why I also bought the same 3-liter cans. In addition, here the value for money is clearly better. The rims were super clean, without wipe and polish. For safety, I have but I also ordered the recommended care products, let's see how this is so.
