vinegar, from the french
vin aigre, or sour wine.
ACV comes from apple cider, which comes from apple juice. wash your floor with it, and if it is cheap enough stuff, you will have a big sticky mess. i want to say that WV comes from grain, but i have to double check on that. you can use it on hair. i'm not a big no-poo'er (only when i am too broke to buy S and C), so i dont know how well it works.
ok, i found
this.
i guess from what i looked up, WV comes from the second fermentation of ethyl, or grain alcohol. (found lots of links to sites for celiac ppl, they cant have most grains, so there is a question of if they can have vinegar.) some ppl use grain alcohol, or even vodka, for preserving their homemade cosmetic recipes. iirc, its about $10 for maybe a quart or so. (i know that's not how booze is measured, but i'm not much of a drinker anymore... lol). WV is $2 a gallon. i wonder how easy and economical it would be to buy a bottle of GA and make your own WV. then you'd have the GA on hand for making up bottles of stuff...if anyone knows, fill me in!
OP, hope this helps you some!
