The 8:3 for 28% acetic acid to glacial is the standard. That gives a nominal
strength to the glacial acid of 75%.
I suggested the use of white vinegar which is about 4-5% acetic acid. That
is a lot more pleasant than strong acetic acid which is a real nose thriller
and there is no risk of burns either.
Note the extra water should be omitted so the alternative formula should
Pot permanganate 6g
Common salt 13g
White vinegar 1l
