Save your used aluminum foil...its great for cleaning grills, tire rims, etc.

Wasp/Bee stings...you can also use tobacco soaked in water or chew it if you don't mind the taste. Place it on the sting.

Vinegar...cleans and kills most bacteria better than bleach. It also will take the 'heat' of a sunburn. Sit in a tub of warm water and pour over skin, then soak in water for a few minutes.

Baking soda is also good to clean brass and silver...just make a paste, add a pinch or two of salt...clean, rinse and dry with a soft cloth.

Lighter fluid used in small lighters is good for removing oil stains, like chocolate, bubble gum, etc. Just pour around stain and then wipe with a wet hot cloth...wash with regular laundry and most stains will come out.
