"apple cider vinegar" + uses
This will return lots of sites that give uses - both healing and practical. I use it for lots of things, final rinse after bathing (remove soap residue and restores acid mantle to skin), great for dealing with candida outbreaks on skin, before a liver cleanse to help soften stones, in rinse cycle of washing machine, in some salad dressings. I make some "grilled" onions with water and a little apple cider vinegar.
I just realized you said vinegar - not apple cider vinegar. The only thing I have every used white vinegar for is cleaning out humidifer and the coffee pot at work. The stuff makes my stomach hurt. I only use ACvinegar, I buy it by the gallon.
Good luck on your hunt. just use vinegar + uses for that search.
