I'm a fan of using vinegar for many things too. I use it in the dishwasher as a rinse aid instead of the expensive little bottle of cascade rinse.

I also use it in place of fabric softener in the washing machine. It leaves the clothes clean and soft and removes any soap residue if there is too much soap on your clothes. It doesn't leave a vinegar smell on the clothes either.

Another favorite use is washing windows and screens with vinegar and water solution.

I have a brick fireplace. From time to time, I brighten the brick up by using 1 cup vinegar per gallon of hot water. I use a sponge and apply the solution to by brick.
