Shower Wall and Glass Door Cleaner

White vinegar, heated
Dry borax

To clean hard water spots and scum off shower walls and glass doors, use undiluted, heated white vinegar.

Put heated vinegar into a spray bottle, spray on and let soak 15 minutes. Using a nylon-covered sponge, apply dry borax and scrub. For really stubborn problems use a dry, soap-filled steel wool pad on a dry shower.
