Vinegar tips - Hard water stains on your bath tub removed with vinegar

To get hardwater stains off of the bottom of your tub, use a paste of vinegar and baking soda. Don't use this on fiberglass as the baking soda could scratch but on porcelain and cast iron tubs it is great!

You can also wipe your tub down with a full strength solution of vinegar to cut grime and soap scum.
