G’day; I always use 10% sulphuric acid, but battery acid would
work too. Or, if you don’t fancy having acids about that would
make holes in your shirts, then you could use sodium bisulphate
(sodium hydrogen sulphate) - lavatory cleaner, called Harpic in
NZ Aussie, and Britain. Use that hot; strength is not
important, just some of the crystals in some water! Some people
have their pickle in an electric crock-pot, but do keep iron out
of it. Use plastic, copper, or brass tongs to take it out of
the pot. Cheers,–
