Removing zinc plating from screws - overland - 01-12-2016
Screws that show will look much nicer if you remove the zinc plating. There's been a lot of talk about the best way to do this. I found out yesterday that leaving them overnight in ordinary white vinegar does the trick. It's cheap and safe, too.

Muric Acid does the trick in a few seconds
If I want them darkened, I heat them up with a torch and drop them in a small container of BLO.

Dumb question: how long do you leave it in?
(From a guy with a case of 'The Works'.)

Not too long. The active ingredient in The Works is HCl aka muriatic acid. It will eat the steel if you leave it in more than a few minutes.

Some of the older screws may have been plated with cadmium which as I understand is very toxic..I think cadmium has been "outlawed" for that reason.......In any case, it would be wise to provide adequate ventilation when using the acid...And make sure to neutralize the acid left on the screws, in baking soda when the plating is removed...The steel can rust in minutes afterwards, so it's best to make sure they are oiled when finished.
