Nitric acid/silver nitrate stains
I just had a glove leak today when I was working with my silver purification. My right glove leaked and I didn't realize it at first, now I have
black and brown stained fingers and hand. Is there anything but time that will remove these stains?

Sandpaper +1.
But be happy, there are several things that can color your hand and looks much worse

i am going on a week with stained hands and at least eight of my fingernails blackened by nitric acid. its common for me to go about with one or two
damaged nails but 8 is going to be pretty bad.right now i got my nails covered with white nail polish and it has slowed my nails from cracking all the
way.if the nail polish doesnt work then i will have it pretty bad for a week or so of painful raggety nails as nitric will weaken nails. i have had my
nails crack all the way down passed the middle and have waited until they grew out again,it really sucks because they snag on everything. i just plain
forgot about gloves and i dont even want to know what people think about me when they see my hands.

Luckily, my solution was pretty loaded down with silver and base metals at the time or it would have been worse. I was only working with ~33% nitric
to begin with and it had been working on 350 grams of sterling for a while.

I don't think there is other efficient way to remove the stains than time and skinning.![:P](./images/smilies/tongue.gif)
Because the stains it self is reacted keratin.Silver react with keratin to form light sensitive compound and nitric acid nitrated the keratin.

Nope! We've all had 'em. The stains will be with you until the skin eventually wears off. You will have a nice long time being reminded of your
negligence.
This experience helped me enormously when I was actively playing with chemicals. Made me really cautious about contamination. And thus, even at my
fairly advanced age, I do not have the shakes, the heebie jeebies, or the creeping crawling internal crud we call cancer.
Silver Nitrate contamination on skin, produces a flashy but benign condition, that reminds us of our mortality, and the power of an invisible amount
of a chemical to have a profound effect upon us.

Had to take the Pediapaw to my own nails instead of the dogs. Sheesh, I'm getting more use out of it then she does.

one week has passed since i damaged eight of my fingernails and have to say that nail polish has helped a lot.my nails will begain to crack almost
immediately if a chunk of nail polish breaks off and leaves the nail exposed. i think i'm gonna beat this and am starting to love nitric again... and
revlon.
