Revive dead car batteries
If you get behind the wheel only to discover that your car’s battery has given up the ghost — and there’s no one around to give you a jump — you may be able to get your vehicle started by dropping two aspirin tablets into the battery itself. The aspirin’s acetylsalicylic acid will combine with the battery’s sulfuric acid to produce one last charge. Just be sure to drive to your nearest service station.
Remove perspiration stains
Before you give up all hope of ever getting that sweat stain out of your good white dress shirt, try this: Crush two aspirins and mix the powder in 1/2 cup warm water. Soak the stained part of the garment in the solution for two to three hours.
Restore hair color
Swimming in a chlorinated pool can have a noticeable, and often unpleasing, effect on your hair coloring if you have light-colored hair. But you can usually return your hair to its former shade by dissolving six to eight aspirins in a glass of warm water. Rub the solution thoroughly into your hair, and let it set for 10-15 minutes.
