How much Potassium Permanganate has to be added to a quantity of water to (A) sterilise it and (B) make an antiseptic.

Cheers.

Light pinkish colour for purifying... 2-3 crystals per litre.... Bit darker for antiseptic. But it can burn if to strong so a case of test to find out.

Not used it, but this is my understanding of it. Hopfully someone will confirm this

Yep thats about right for sterilising water. Just the tiniest amount to very lightly colour the water. Dont know about burning you though, its used as a solution for foot fungal infections. I've had it on my hands in neat form and then splashed water on them and I've not been burned,brown maybe but not burned.

Just be aware that it takes the tiniest amount to color water. I made the mistake of buying 250gms, it should last me around 174 lifetimes.


I can also testify to having feet David Dickinson would be proud of.

It absolutely doesn't burn. Stains like mad though.

When you soak hands or feet its the deep colour of methylated spirits at least.

Happily ill stand corrected on the burn front. Only based it on looking into it before where various sources say it can following repeated use. Not tried it myself yet though.

I have unfortunately had to use the PP baths a few times. I managed to get an infected rash on my hands.

It doesn't burn. It might dry your hands a bit and it absolutely will give you the tan of an Essex girl.

To make it combust you have to add glycerine.
