I saw the answer to this somewhere but can’t find it anywhere.
Please help me if you can. When I solder brass it turns red like
copper. When I pickle it, it only goes back to pink. I saw that you
can get it back to brass clor if you soak it in a solution of ammonia
or vinegar and hydrogen peroxide. What I can’t find is was it ammonia
or was it vinegar and what are the proportions. In other words,
what’s the recipe?
Thanks in advance,
