Need a good quality (ie powerful / strong) wheel cleaner that's safe for ppf and won't promote disc rust. I realize that I just need to make sure the brakes/wheels are completely dry after washing which is best achieved by driving and/or using a leaf blower. These are my wheels.

As you mentioned, there is no real way to completely prevent rust on rotors after washing, unless you have PCCB’s. Sonax wheel cleaner is a strong and safe cleaner that is PH neutral.

Brake buster from P&S is definitely not as strong but does have corrosion inhibitors built into it, but my discs still rust after.

Hydes Serum rust stopper is a product you can try to prevent rust, but it only helps a bit. Best thing to do is drive down the street to remove the rust after washing.

 

Take the he wheels off and wash one by one.
