We all know that vinegar can be used for pretty much anything and everything. One of the newer uses I came across is to replace the expensive dishwasher rinse aids. I've been using it for probably 30-40 washes now and you really wouldn't know I was using vinegar instead of the expensive rinse aids.
I know there's a list that went around and around about the many uses of vinegar, but I didn't save it. Here's a site though that has tons of uses. 131 in fact.
