Need help with wheels

[FUNX650]

I inadvertantly left sodium hydroxide off this list from post#30.....it's some bada$$ stuff (will eat aluminum up!!) :

It is recommended to not use any products on polished aluminum that contains any ammonia (ammonia attacks the zinc that's often found in these castings), acids, and it should be anhydrous. Also, avoid products containing sodium hydroxide.

Also, if it is, in fact, HF (hydrofloric acid) try to get some calcium carbonate to keep on hand. HF has an affinity for calcium and even a tiny portion on your skin will quickly migrate to your bones. Rinse the affected area and apply calcium carbonate to attract the HF. The problem is that in some states calcium carbonate is a prescription item, but most fire departments keep it on their ambulances. You do not want to use HF without PPE.

Sounds like you bit off a huge chunk and I'll bet your employer will be less than satisfied with the results. But that's what you get when you neglect bare aluminum wheels for 10 years.

Maybe soda blasting would help.
