Cleaning running boards
 

I just got a 07 3.0 with the aluminum running boards and noticed there is a little bit of rust around the rubber buttons....anyone got the best way to keep these clean please?

Thanks

My 2012 CPO X5 with running boards also has brown stains suggesting rust, but aluminum corrosion is not rust colored or rust per se.

I'm still working on the paint, polish and finish and haven't yet gotten to the discoloration.

The rust on the RBs is from metal particles in the brake dust that settle on the RBs and rust. I've had good luck with using a high quality wheel cleaner to remove the rust spots on them...
