GMC Wheel corrosion

[iron man]

A few days ago, I spent $350 on 4 Futura Scramblers that were practically brand new that were mounted on stock 16'' GMC Yukon wheels. Problem is, these style wheels, "polished" alloy wheels like to start corroding from road salt, car wash soap, car wash water, dirt, mud you name it they start corroding. The pics are on my phone, but there are also a few rust spots where the weights once were to balance the wheel. I really want to take all of this corrosion and rust off and make them "shine" as best as I can. My dad said brillo pad that sucker up until it shines but that takes hours to do. Anybody know of any tricks to get the corrosion off as well as the rust which kinda is corrosion anyway before I take a brillo pad to them?
