Discoloration by metal

Unfortunately, a means to counter this is yet to be found. Latex reacts in connection with moisture, salt and in particular non-ferrous metals (brass, copper, gold, Nickel...) and can become unattractively discolored. These discolorations are mostly yellow to brown and very unpleasant especially in light latex. The only solution however is prevention. As such, special care should be taken for example when using latex and jewelry or piercings. If in doubt, preferably omit or remove it before it discolors.
