My Boxster has both the paint protection film and ceramic coating. With respect to the painted surfaces, after a year of experience, I am very satisfied. It really does almost wash itself clean by driving in a heavy rain. However, even though the wheels are supposed to be ceramic coated, it is a time consuming pain in the ass to clean the heavy accumulation of tenacious brake dust. A direct spray from the hose does nothing consequential. Although the brake dust does wipe off relatively easily, every square nanometer of surface, nook, and cranny must be wiped. I use a variety of brushes but cleaning the four wheels consumes much more time and effort than washing the rest of the car so I am looking for a better solution. I also wonder about the effects of the spray of brake dust on me as I use the brushes to aggressively get into all the nooks etc.
Worx markets two battery powered pressure cleaners. These devices look like they have the potential of making wheel cleaning very easy and quick. This is assuming a 320 psi or 450 psi (depending on model) will wash away the brake dust. If it does eliminate the need to manually wipe/brush the wheels I will buy one immediately. However, I would first like to know if anyone else has used one and how effective it is blasting off the brake dust. There are two models, a 40V and 20V with rated pressures of 450 psi and 320 psi, respectively. Are these pressures sufficient to remove the unsightly brake dust?
