Use to clean, brighten and transform badly corroded aluminum to its natural appearance.
Worked great! Had a spider from an older HE3 Whirlpool Front Load washer go bad. Got a good used one that needed a good cleaning. Afterwards a basic wash in C-IC 33 AERO to remove whatever it removes :-) and water no longer beaded, and coated it in enamel to protect against corrosion as recommended by other techs. Well see how long this one lasts!
This review is for people like me in search for the magic chemical that will clean heavy oxidation from cast aluminum (transfer cases, engines, etc.). Im sure this product would be a 5 star for airplane painting. For my application I thought this is the killer product that will save me from doing media blasting. It works some but only when used undiluted and using a lot of elbow grease with a wire brush (use stainless steel). I tried it on a small and simple cast part. I was hoping for a good results on this project so I can later use it co clean a transfer case/differential that has too much details to want to scrub by hand. A chemical solution would be ideal. Unfortunately this does requires a lot of scrubbing to get heavy oxidized aluminum bright. To be fair I tried a lot of chemicals and none was great. Actually this is one of the best but still not good enough for the job. Im sure this would be great for painting airplanes used as directed. But Im not paining any airplanes.
Good chemical to preclean aluminum prior to painting to remove oxidation. Best shipping prices.
Done what was expected, Cleaned very well.
works really well diluted per instructions
