I have the standard 2003 5 spoke clearcoated polished aluminum wheels and have noticed spots that are not coming off of them. They appear to be water spots and are concentrated around the center of the wheel. I dry the wheels after every wash and do not allow the water to dry. I do use Bleech-white and Meguiar's tire gel, but I'm very careful when using it and try not to get any on the wheels. The only thing I can think of is when I wash the tires/wheels and spray them first with a hose, the gel appears to slightly come off a bit because the water turns a little milky as it runs off the wheel and tire. If tried wax and polish but nothing touches the spots. Short of having a shop strip the clearcoat and re-apply it, is there any product out there that will remove these?

Thanks!!
