For years, I use only the NIGRIN wheel cleaner. Whether I einsprühe the wheels before the car wash or even short by a stop between the self-service laundry room inlaid with the product I get jerk twitch throughout the muck from. I'm talking about the way not only from the front, but also on the rim. Since I've always used scratched hands on the brake disc. As some here hold forth on the spray head here my tip: forcefully press the trigger completely and take a pause for thought before the next sprayer, then there's a decent spray! Those who do not should just not buy products Men;) Oh, and where I can not the means hinsprühe also not clean - sounds weird but is so ... remedied before rinsing times' nen meters vorzurollen to the underlying quest also sprayed, then it's perfect.
