Well obviously you don't want to breathe in the vapors, or get it on your
skin. I do it outside, and stay upwind. Chemical gloves, a mechanics
suit, safety googles and a face shield are necessary, and make sure you are
not near an open flame. Have a box of baking soda nearby for spills and
I put the part to be de-galvanized into a plastic container, and use a chip
brush to apply the acid.
As the procedure continues, you will need to add more acid, as you end up
converting the Zn into a ZnCl solution, and releasing H2.
Like most things, once you have the setup it is a relatively simple
prodecure, and kind of fun.
The stronger dish machine soap along with the hot water removes all oils
left over from the manufacture. It also tends to dull the surface so that
paints sticks as well as paint can stick.
The process is about the same as a years exposure to the elements which is
about how long you wait if you want paint on metal flashings to adhere well.
Oh, it will just fine. I built some structures this past year using
Unistrut for parts of them, and needed to strip the ends for welding.
Vinegar strips the zinc plated ones overnight, and the galvanized ones
take a day or so.
do you how baking soda figure into white vinegar? I've seen comments
where they say after the zinc is stripped from the metal, neutralize it
with baking soda and wash it in soapy water and rinse it in fresh water
& dry. whats not clear from the comments were, are they neutralizing
the vinegar acid or the metal or both.
