Wise Bread is one of my favourite sites for green and frugal tips. I read their article "30 Household Products Vinegar Can Replace".
I already use vinegar and water to clean my windows, tile and shower doors. I'm so pleased to now have a full list (and recipies) of other great uses! Who knew you could use it to remove the onion smell from your hands, be used to remove grass stains from cloths, treat acne, or as a window defroster in your car?
Vinegar is cheap (2 pack of 1gallon jugs $3.38 at Sam's Club), easy to find, doesn't have harmful fumes or harsh chemicals and it's a GREAT cleaner (nothing else would get my shower doors clean or my bathroom mirrors streak free!).
It's also not harmful to our septic tank or our 3 year old son, who loves holding the spray bottle to help mommy clean! For health questions about vinegar, go to the National Institutes of Health.
