Frugal Dad recently published a good article on the many uses of vinegar.
I've found vinegar to be very helpful around the house - cleaning, as an air-freshener, in laundry, etc. It's kind of a miracle liquid, and I'm sad that most people don't know about its many uses since it's much better for the environment than most household cleaners. Some people have a problem with the smell, but if you add a little bit of essential oil (whatever scent you love - I suggest lemon or citrus) to the solution, it'll cover the vinegar smell.
