Your aluminum wheels are most likely clear anodized and corrosion might have gotten under the clear anodizing layers, so the cloudiness, dark and light spots you might have on it are basically trapped under the finish and cannot be taken out unless you remove the anodizing on the rims. People have used lye based products like oven cleaner to remove anodizing from parts and have been fairly successful, but you have to be careful when you do use them as they are caustic and can hrm you skin if you are not careful You can polish off anodizing with a buffing wheel and some abrasive compound, but it will take a long time and a lot of messy effort to do so. IYou might consder just buying new rims or wheels if you really want perfection.
BTW, once you remove the anodizing from the aluminum and polish it up to maybe a mirror finish, you will have to maintain the polish by toudhing it up with the buffer and polishing compound once in a while. The rims will actually corrode/dull faster without the anodizing on it.
