When I wash my 911 C2S the wheels/brakes are a challenge. Well my carrera classic wheels are a breeze to wash and I can get my hands all the way in to clean the wheels fully. My challenge is that the cross drilled rotors seem to hold endless dust. I thoroughly purge them with water and let the car sit to dry and tire shine. Even 45 mins afte or wash a quick drive will yield rusty water on the interior of the wheels. Are there any clever ways to resolve this or do you have to let the car dry for hours before driving? At present I just keep a towel to re-clean the wheels after the 1st post wash drive.

 

I wash and dry the car and then take it out for a drive. When I get back I go back to the wheels and touch them up. I also touch up the doors behind the mirrors and around the tail lights. Those seem to be the areas where I get stains from accumulated water.

 

You would almost need access to compressed air with an attachment to just blast the water out of the rotors & calipers. Alan's method above is probably just as effective. Some shop-vacs can be used as a blower too. Mine allows me to move the hose to the air outlet and it will blast pretty well. Don't use it on the body, though! Only the wheels

It sounds like that's the ticket. I won't miss the mess on the inside of the wheels!

 

All the rinsing in the world is not going to stop at least some dirty water from eventually finding a way to drip on your just cleaned wheels. After cleaning and rinsing you have to get rid of the water that is just sitting in all the nooks and crannies of your brake calipers and rotors.

I use an electric leaf blower (electric, not fueled) with a shortened funnel* to blow out all the excess water from places that can't be reached with a towel. Works great on tail lights, markers, or any other seam or gap on the car. I even use it to blow the water off of the body which saves a lot of wiping and re-wiping, making it almost a touchless job to dry the car. Even the wheel wells can't escape a good blow down to get rid of excess water trapped in those areas. I usually do the tires and wheels/brake and rotors last as the blower's motor has by now warmed up enough to transfer some of the heat to the air to help further dry the car.

(* I shortened the funnel with a hacksaw and then used a heat source to soften the plastic and smoothed the cut end to prevent any possibility of a ragged edge contacting a surface. Total length of the blower and funnel is now about 18" which makes it easy to maneuver around the car.)

 

Another leaf blower here.
I just washed and blew dry my car yesterday. Took the ankle biters for a ride after and I didnt notice any nasty water on them (the wheels, not the kids).

Give the leaf blower a go. Now that Ive said that I bet I will...
