Paint on aluminum rim

Doing some wheel/tire switches today, got better arrangement now with tread depth, pattern etc., now we have one aluminum rim, facing outward and low and behold, in the past someone painted this rim black. Other than dismounting the tire, and switching rims, what’s a easy, effective way to remove paint from an aluminum rim? TIA

 

I thought of that but that tire is a little bit more worn down than the outside one, and with the curvature of the road, I always figured if one just slightly taller, put that one on the outside.

 

Just to update, tried oven cleaner that was a no go. Evidently hi-temp paint must have been applied. Short of paying out of my own pocket for sand blasting, I switched rims, tire is in the same position, but now with a clean rim.
