Rust Marks of Brake Discs

[tino23]

Every time I wash my wheels with cleaner to remove brake dust from my 2000 996, the discs develop brown rusty spots. Should I be concerned? They seem to burn off after getting the car on the road the next day and using the brakes, but I am concerned. If anyone else has noticed this please let me know and how best to avoid this in the future.

What wheel cleaner should I be using, if any?

Thanks for your help.

Normal. You need to drive the car after washing (carefully) to dry the brakes.

I like P21S gel wheel cleaner as it "sticks" to the wheels and does not harm the clearcoat. Changing wheel cleaner will not affect the rust issue - you still need to drive the car to dry the brakes.

Thanks! I never heard of the gel. Is it available at most auto stores? Also, do you use a brush to clean the inside part of the rims? I've been using a sponge and a sometimes cut up my hand on the disc and other brake parts. Looking for an easier way to clean!
