Also pretty easy, with Goof Off, and some scraping.

Step 6: Attack the crud inside the wheel with cleaner. Note, this wheel and one other have a pretty solid coat of hardened brown crud.

I tried letting the cleaner sit for about 20 minutes, and then scrubbing with a Scotch Brite sponge. A lot of scrubbing.

After about an hour of scrubbing, this is what I got: partly cleaned but still lots of hard crud.

I decided to attack the remaining wheel that had "normal" dirt. About 45 minutes with the wheel cleaner got this.

I will try one more time (waiting on a different wrench to get into the small spaces around the pressure valve). |

Still working on the two extra-cruddy wheels.
I left one wheel with Chemical Guys cleaner overnight, wrapped in a plastic bag. I was hoping for some magic, but after scrubbing and rinsing, most of the crud is still there. Attached thumbnail(s)

Based on something I found on the web, I tried one more material: iron removing liquid. I think this is based on the idea that the crud is a mix of dust from the disk, pads, and road grime.

First application: as it works, it turns purple. It also smells pretty bad, like old-fashioned hair salon perm fluid.

Unfortunately, my bottle of Iron-X was almost empty, so I only got about one-fourth the way around. More stuff ordered.

One thing I found useful in cleaning the anodized Fuchs on 911's was a mixture of white vinegar and hot water. Not sure if that would be helpful for you on the front sides? |

This is one project I am not running towards, just spend a few hours cleaning the exterior surfaces of a trans.
Thanks for posting Bob |
