disk rust

How do you clean this up and then prevent it from happening again?

How do I clean it up?  I don't. Only way I can ever get it off is to drive it even if it's just back and forth in the driveway. Only way to keep it from happening again is to replace the rotors with ceramic rotors.  You can also buy caps that will cover that rusty area.   It's a pain in the arse, but that's the ony way I've ever done it with my Vettes.

What I have done in the past is clean the rust with a wire brush.  Then I prep the surface with some brake cleaner and then paint them black.  I use caliper paint to paint them.  This will keep them from rusting.  Of course this is done with the wheels off. 

 

You could even do the outer part that is also rusted. 

 

Next time you are do for some rotors buy some that already have the rotor hats and veins black.

The part of your rotor that doesn't come in contact with your brake pads I alway paint, usually it comes gray so I use gray rustoleum paint.

As mentioned above, just you some shake and shoot, then just do touch-up if needed, when you rotate your tires.

I used Rustoleum BBQ black paint on mine and really lik ethe look. Not too black, just a nice black / gray color. Otherwise satin blak works great. Pull the wheels, use some Scotch Nrite to clean them up, mask the braking surface and surrounding areas of the car, then spray.

If you have lots of time, obviously you can pull them and do it right.

Awesome product, that's darn near bullet proof!

Use/prep/apply exactly as instructed.

Por 15 makes some pretty good products, IMO.

After spending a long time carefully washing, drying, and applying wheel guard to my custom 2 piece wheels, it's so frustrating to see that within 2 minutes of driving out, the rim barrels and some of the lips are now covered in rust residue from rotors that got wet when washing. Aside from immediately drying with my metro vacation on blower setting, is there any other suggestions to prevent or minimize this?

Wheel guard wax and sealants help in removing the rust dust but would like to not have to redo them over again the minute I get to car shows or meets.

Omar, you kind of answered your own question.

I run into a similar condition on my car, but if I use my Master Blaster first to dry the wheels and exposed brake components, with my wheels completely sealed (including barrels) after I drive it, usually just a quick wipe down cleans them right back up for shows.

 

Only other alternative is to limit the amount of water you get into the brake rotor area to prevent the rust from happening in the first place, or else replaced the rotors with others with a coating which prevents it from happening. They are available for some vehicle applications.

Thanks Rob. That's usually my order of detail as well but was simply asking in hopes of a different method. My brakes just seem to create lots of brake dust. Once I'm due for brake job I'll most likely switch to carbon pads.

Whenever I go for the first drive after washing my car, I take some QD/Detail Spray and a black MF towel and wipe the wheels down (when cool), assuming its a short drive.  That initial rust from the rotors drying comes off real easy, and once its removed, your wheels stay cleaner 2-3x longer, because there isn't anything on the surface of the wheels to "stick to", and if your wheels are sealed you will notice they are even cleaner.

Lots of good tips in here already. Pretty much theres no way to stop it short of pulling the wheels, scouring the existing rust off (with a wire brush) and painting the rotor hats with appropriate high temp paint. The faces of the rotors will rust anytime they get wet and dry, but the good news is that surface is scrubbed clean the next time you tap the brakes so its not a big deal.

Mine were starting to rust, so I prepped and painted the rotor hats when I painted the calipers.
