I have used oven cleaner to remove the adonizing from aluminum parts before. Not sure if it will work on the wheels, but I don't see why not.

Don't know about all those home remedy ideas, but the easiest would be to check into a local anodizing shop. I took some motorcycle parts to one, and all it took was a few minutes. After they dip in into a tank of something, there is no trace of the color anywhere.

i have removed the gold anodizing b4. i used sodium hydroxide (i think). i was able to convince my high school chemistry teacher to let me use the chemicals and do it after school. make up a diluted mixture and rub it on with steel wool. it takes a little time but it will work. when u are done shine them up with mothers mag and aluminum wheel polish.

Here is your answer... I too have some gold annodizing that I have to remove

, so I took the liberty of finding out how.

You can strip off the existing anodized layer from any anodized part by placing the part in a Lye solution for an hour or so. Just mix up a few tablespoons of lye and water in a plastic container. Wear eye protection and rubber gloves for this procedure!! Place the part in the solution and monitor its progress. Most anodizing kits supply stripper. It works a little better than Lye and will not pit the part as easily as lye can if left unattended for too long.

The lye will dissolve the old anodized layer, about .0005" thick. It takes a while for it to start breaking through the layer. It's a little slow at first. The first ten minutes or so not much action will be seen. Bubbles and smut will rise up as an indicator of its progress.

It is a good idea to help the process along by wiping the smut off of the part to allow the acid to get to fresh aluminum. Just wipe off the part with a rag every 5-10 minutes until the old layer is completly gone (wear gloves and goggles). Only bare aluminum should be seen when the part is finished. Again, anodize stripper works harder on the oxide surface and less on raw aluminum. This is why it will not pit the part as easy. Once the solution breaks through to raw aluminum the process slows down. This is not the case with Lye. Lye starts dissolving the bare aluminum and can cause pits once it breaks through the anodized layer.
