If you workout (or even if you don't), chances are you sweat. Any good exerciser has one or two favorite shirts that have acquired the yellowish sweat stains in the armpit area. That is the worst.
Here's a unique way to get rid of those nasty sweat stains from gomestic.com:
To remove perspiration stains from white T-shirts, dissolve two aspirins in half a cup of warm water and apply to the area of the fabric where the stain is. This should be left for a couple of hours before washing.

Yellow or green hair from chlorine in a swimming pool can be remedied very quickly by dissolving 8 aspirin tablets in a glass of water and rubbing the resulting liquid into your hair. Leave for about ten minutes and then rinse it out. Shampoo in the usual way.
Easy, right? If you try it, let me know how it works.
