muriatic acid (Hydrochloric Acid)!I have some hardware that I want to remove the old anodizing (sp?) off of. How do you remove old anodizing?
I haven't tried it, but I've heard that EZOFF oven cleaner works.muriatic acid (Hydrochloric Acid)!
They also have some commercially available removers out there, but I can't remember what they are, I've got a few of them bookmarked, so I'll put them up later.
Well I do hard anodizing and when I need to strip it the stuff I mentioned WILL work. A Pro told me about it so I tired it and yup, back to the original aluminum finish! Don't take my word for it, go with all the harsh stuff and wear protective clothing, goggles, face shield, and gloves. handSorry, I was thinking of removing hard anodizing. You need some bad shit to remove that.grn
I'll go along with what everyone else said to remove the anodizing. Good luck.
I'm just regurgitating what I was told by a drag bike builder, about a year ago. I never tried it because it sounded a little hairy to me, but they use it all the time to clean bricks on the outside of houses. That Greased Lightning probably works on the regular anodizing, but I don't know, I use it all the time to clean painted parts, and it just barely strips the paint off. And I don't really believe you about that Greased Lightning on the hard anodizing (I would have to see it for myself) because that is what I used to clean an extra pump bowl that I am having polished. And I use the shit straight up, no diluting (I don't have running water at my shop) and that hard anodizing is still there, I accidentally let it dry on there a couple of times. It's hard as shit too, sparks fly when you put a grinding wheel to it. The thing about the hard anodizing is that it is actually part of the metal, it goes down into the base metal about 0.005" to 0.010" if I'm not mistaken. So it takes some serious shit to remove the real hard anodizing. This has just been my experience and what I have dug up in researching it a little, awhile back.Well I do hard anodizing and when I need to strip it the stuff I mentioned WILL work.
