Vinegar

White vinegar can be used to clean many things including chrome, windows, mirrors, hard water deposits, and coffee makers.  Vinegar can be used full strength or diluted depending on the use and the item that is being cleaned. 

Mold:  Mix 1/2 cup of water and 1-1/2 cups of white vinegar in a spray or squirt bottle.  Place mixture on the mold and let it sit for a few minutes then wipe.  The mold should remove.  Depending on the degree of mold you may need to repeat this procedure.

Clean the can opener with a toothbrush dipped in vinegar.  This can be done on the blades of an electric or a manual can opener.
