ferric chloride,ferric sulphate,sulpuratic acid,muratic acid, photographic fixer,whosteerchester sauce,pinnaple,lime,lemon and various vinegars are common to use.Some are salts some are acids I would strongly suggest you learn something about chemistry before using these. Some of these are extremly toxic and need to be greatly diluted to work properly. You can also trash the piece very quickly
