I though u just snorted things to see if they were safe Tadgh
I haven't made much homemade stuff in a while , i might make a batch of high PH powder for occasional use , il add a bit of sodium hydroxide to boost it to PH 16
I would make my own citrus prespray , but mistral dont sell D-limonene for some reason and the shipping from the uk is a killer from the ones iv seen so far .
