Default How to strip nickel plating from brass?

Is there any safe way to do this? I want the natural brass-looking color on my Hope Leo.

Well... There's muriatic acid... But that would probably attack the brass too fast for it to be worth it...

The only other method I could think of would work great on thick layered nickel. 3 parts sulfuric acid to 2 parts water by volume. The apply a positive DC charge to the stem and a lead cathode. 6 volts should be fine. Do it in an extremely well ventilated area. Preferably outside. Adding extra water will speed up the process but increase pitting on the brass. Adding 30 grams/litre of copper sulfate will reduce pitting on the brass.

Something like dilute hydrochloric acid MAY work on thin layers.. never tried it.

Figured I would make something alittle more clear. Muriatic acid is the same as hydrochloric acid. The only reason I used both names, is because the second is diluted. And I have never seen it listed as diluted muriatic acid where it was easily accessible.

DISCLAIMER: although the information I have given is accurate I am in no way responsible for any bodily harm, loss or damage of property, or any other such liability. It is the sole responsibility of who ever uses this information to take the proper safety precautions. I am in no way responsible for your stem if it ruins it.

If you want to search it further, search for "stripping nickel".

I think even if you do strip it, you might not be pleased with the results. You'll likely be damaging the detail on the body of the stem, and as stated, it's possible for pitting to occur on the brass if you don't do it perfectly.

Pitting will more than likely occur even if done properly. It's to what extent that matters.

I'm sure a Chrome shop could dip it and take the nickel off then polish the stem to get rid of what little pitting that may occour for relatively cheap. The only reason I do this at home, is I work with large parts, and Chrome plating started to cost to much so I learnt to do as much as possible in house... No reason you couldn't do it, but the window for error is very minute. What ever you decide though, good luck.
