PLEASE do NOT consume synthesized vinegar. Use only organic Apple Cider Vinegar in food. Use the cheap synthetic vinegar for all of the household uses listed. Also: you can get a good deal of the pesticides off non-organic produce by soaking them in a sinkful of water into which you add: 1/2 cup Vinegar (synthetic is fine for this use as you'll rinse it off), 1 Tbs. white Salt (ditto. White salt isn't for eating, but you'll wash it off), 2 Tbs. Baking Soda.
