Vinegar for galvanized removal
« on: November 18, 2019, 11:31:54 AM »
Hi all..

As I mentioned in another post here I am redesigning the custom manifold I built awhile back to fit 2 SU sidedrafts to my 2.0 and am planning to use some 1 1/4 galvanized EMT conduit for runners.

Since its not advisable to weld galvanized i want to remove the zinc.

I have  been reading that vinegar can be used to etch off the zinc..

Has anyone had experience with this

If not vinegar then likely phosphoric acid. But, even there you will have to likely lightly sand the surfaces if it works. Recently working on my Corvair I have used the washing soda and a sacrificial steel piece to transfer rust. I'm wondering if you could do the same to remove the galvanization???

I was thinking of using concentrated vinegar and adding some table salt to make hydrochloric  acid to speed up the process and maybe warming the solution a bit and placing it in the sun to keep it warm.

Ill give it a try and report back.

If you see white powder on your weld there is still zinc present.

And, isn't it interesting that the "Weld Thru Primers" as far as I know contain zinc. Go figure.
