how to remove oxide from aluminum?
I have a grayish discoloration and some minor white accumulations on the sides of installed crankcases on a 31 year old motorcycle. I've tried numerous commercially available aluminum cleaning products and some home remedies with little success.
Are there any home chemicals such as oven cleaners or scrubbing bubbles that will remove the gray haze that I assume is aluminum oxide. Whatever application that may be suggested here must adhere to the installed cast aluminum parts. Hoping to connect here with a chemist that knows the answer. Maybe there isn't a magic wand to this problem? Fingers crossed. thanx in advance from an old guy.

The crankcase is likely an alloy, in which case it would be best if you knew the exact composition. It might take a bit of digging (like contacting the company that made your MC) but it could be worth it. Shiny vehicles are really nice.
If common cleaners won't do, I wouldn't go trying oven cleaner without more information. In the early years of our marriage, I put some FeCl3 in an aluminum pot and there was a mess that was beyond hard to clean up. It's a good thing I had a tolerant wife.
Oven cleaner strikes me as the same way. Aluminum is very reactive. Maybe someone else will have a better answer.
