Generally medical professionals do not vouch for using milk for tear gas despite it often being touted. The research seems to suggest they are largely the same in providing relief

That means bacteria can contaminate the milk and potentially cause infection if applied to eyes or skin wounds. Jordt says it’s better to use water or saline solutions to wash out eyes after a tear-gas attack
Another source of medical professionals recommending against it
And a study looking at pepper spray as well
In this study, there was no significant difference in pain relief provided by five different treatment regimens. [Water vs milk vs 3 other solutions] Time after exposure appeared to be the best predictor for decrease in pain.
Yeah but no. I’ve been tear gased, and water does nothing but make it worse. The capsacin is dissolved in an oil, and using water will only spread it over your body (and that shit hurts a lot everywhere it touches). Use milk, it will provide instant pain relief. The threat of bacteria in pasteurized milk is the same as in water, and odds are, after dumping milk all over, you’re probably going to wash yourself off afterwards.
if you’re gased, don’t waste time following this bad advice. Take it from someone who’s actually had been gassed, only milk works. Don’t try water.
