For many years i have used a solution about 15% (?) to clean wheels on my BMW's, is this a problem with Porsche o/e wheels?

No HTwo O

The main problem I see, is that the SG will strip off any protective wax you use. I clean my wheels with soapy water. Wax with RejeX.

Been using Simple Green on Wheels and everything for about 2 decades...zero issues.

I've waxed and waxed my wheels beofre and still due but the heat generated by the brakes melts/dissolves any wax type of product right off anyway.

Aluminum - Is it safe to use Simple Green® on aluminum?

Most of the Porsche OE wheels are painted, not actually bare aluminum, right?

Yep...OEM are painted/coated
