Okay, I know this might sound really offtopic. I made a PCB a while ago and got some ferric chloride stains in my clothes. I've been trying literally everything, from lemon juice, salt, vinegar, coke, bleach, sodium bicarbonate... I think it's really difficult to remove, but not impossible. Any advice I can get to save the clothes? Thanks!

  • \$\begingroup\$ The iron has likely bonded to the fabric. The methods of unbonding it will probably destroy the fabric itself. \$\endgroup\$ Dec 11 '16 at 21:10

I kind of doubt the stains will ever come out completely. Why don't you dye them in FeCl and make a fashion statement?

Some UK companies sell FeCl stain removal crystals, which appear to just be Oxalic Acid.

  • \$\begingroup\$ Oxalic acid is also sold as deck cleaner in hardware stores. If it bleaches dyes or burns holes in your clothing... \$\endgroup\$ Dec 11 '16 at 21:31

  • \$\begingroup\$ Oxalic acid will remove iron, but not copper. It is not good for clothes with snaps/rivets/zippers with iron content. \$\endgroup\$
