Posted here, there & everywhere....
What we have here are OEM coated, cast aluminum wheels from a 2004 GMC Sierra. They've seen 60k+ and 5 Ohio winters without ever getting a really thorough cleaning inside and out.
The outer wheels are in pretty decent shape with just a few defects in the coating where wheel weights have been attached. They clean up well and take a shine, they're rarely left very cruddy for long periods. The inner barrels are a different story though.
Believe me, the pics are AFTER cleaning attempts! They were pitch black before!
My primary goal is to clean these up as well as possible and apply sealant and do 'em once a year every Spring. The visible portions through the holes in the front detract a bit from the overall appearance. In attempting to clean the inner barrel I first tried a generous dose of P21S Gel and let it dwell for an hour. The I then scrubbed the surface crud with a wheel brush getting close to the results shown. Thinking I needed something considerably stouter I applied Purple Power APC full strength and let it dwell taking care that I didn't get any of this nasty stuff on the front of the wheels. Not much improvement.
I then attempted a few other things in spots..... of everything I tried a Brillo pad produced the most favorable result with a TON of scrubbing. I also gave a PowerBall a whirl with Wenol red, Meg's Mag & Aluminum Polish and other lesser products with the best results appearing near the openings where exterior cleaning may have kept them from getting as bad as the rest of the barrel. At this rate using the products and methods I've attempted thus far I might get some decent results if I kept at it for a week or so........ per wheel, probably! There's gotta be a better way....
I'd appreciate any thoughts, comments or suggestions that might lead to some improvement. I don't expect perfection after 5 years of neglect but I'd like to improve the appearance, at least what's visible from the outside of the wheel.
Thanks in advance...... TL
