First of all, welcome!
You need to go to the Adams videos on coatings and start there. To do coatings correctly takes some study. Pics of the wheels would help. You have no way to get them off the car?
Right now it sounds like you just want to clean them. How dirty are they? Is it all brake dust? You might be able to get away with using soap, wheel cleaner, and a pressure washer but even then you won’t get it all.
Another question is what are they made of and what kind of finish. Some finishes and chemicals don’t mix.
