Highly polished wheels should not be cleaned with strong chemical cleaners like Simple Green. Make sure the wheels are cool and I would clean them with the P21S Wheel Gel. This cleaner is ph balanced to be safe on ANY wheel and uses no harsh acids to clean with. The gel formula helps the cleaner cling to surfaces liquids just run off of. To remove the water spots your going to need a metal polish like the P21S Finish Restorer. This is a deep cleaning metal polish that helps remove oxidation and other imperfections. I used to not think the towel you applied this product with mattered much but I highly recommend getting a two sided microfiber metal polishing towel. The P21S Finish Restorer and this towel work deep into the wheels surface for a deep cleaning and shining. After I'm done I like add some more gloss and protect my wheels with Wheel Wax or the Poorboy's World WHeel Sealant. These products help protect the wheel from water marks, brake dust build up and more. It saves you time from future cleanings and adds an extra pop to the wheels appearance. Let me know if you have any questions.
