How do you get silver nitrate off of your hands?

Answer 1

You don't.

Correction mister: you can. In the future don't post if you're not sure of something.

I've found out myself that using concentrated Hydrogen Peroxide on the affected areas can fade/even completely remove the stains.

Caution though: although the benefits above have been stated, the H2O2(aq) solution cas cause a slight "yellowing" on certain fabrics.

If used on hands or other parts of the body, the Hydrogen Peroxide will leave temporary white and granulous deposits on skin areas.
