Thanks for the great video, I’m working on restoring multiple old drive-in speakers, which are cast aluminum, and now I know for to use Purple Power on it!
Thanks for watching! Any cleaner with lye (sodium hydroxide, mainly all purple colored cleaners) you should avoid using on aluminum. Mean Green should be safe for aluminum but I haven’t tested that one myself… Yet! Good luck on your restoration!
I absolutely should have. I didn’t think at the time it’d be so destructive to my test samples. I plan to revisit this once I setup some ventilation and test this against a few products to find what cleans aluminum safely and the best
I used it diluted in my parts washer. It removed the paint below the liquid level and dissolved the aluminum filter. It was diluter 8 parts water to one part Purple stuff

I think you should have weighed the test samples
