De-anodizing fail

[r1Bro]

Well I was looking at faster ways to de-anodize , other then spending a hour with a dremel. Through a few google searches I saw a few things people said worked, oven cleaner, toilet cleaner, drain cleaner ect. So I tried toilet cleaner and it didn't work so well. Not sure why though maybe the light wasn't aluminum? Or maybe it was just regular paint? Idk...but now I have to buy another host GRRR

WOOW, That's pretty freaky, maybe you used a highly acidic product, you sure that piece isn't plastic?

100% sure it wasn't plastic. It was definitely some sort of metal. It ate right through the threads, and It only took maybe 5-10minutes... :cryyy:

Look on the bright side, atleast you got the de-anodizing bit done

On a more serious note, you shouldn't have used toilet cleaner, search google for a proper de-anodizer liquid, to prevent this from happening
again.

Also, are you 100% sure the threads aren't plastic?

Use Draino Max Gel. Works great!!!

For sure they were aluminum.


And yea It was my own fault for being impatient. I should of got something made for this, but wanted to try what I had.

Toilet cleaner that eats through alumunium, thats a new one

The cleaner probably had sodium hydroxide in it. This is used, properly diluted, as a wash or light etch before andozing. It can also be used to de-anodize, but if too concentrated, it will dissolve the aluminum very rapidly. This is wh yyour threads vanished. A 1/5 strength solution of phosphoric acid used very hot can be used. Also used is a chromic acid and phosphoric acid mix, again used hot. For some surfaces, fine sandblasting is an option.

Thanks, yea I read that Phosphoric Acid can be used around 200 degrees from 5-10 minutes. Also that it should leave a decent finish, as some will leave a rough finish I guess harsher stuff. I see 85% food grade Phosphoric Acid, I guess I'll try it out
