I started doing this and will never stop! My tub shower are always spotless-so simple. Simple shower and tub cleaner: fill wand half and half. Wet surface and scrub. wow! leave in shower wash while you are already in there.
Bath & Shower Cleaner Recipe ~ Says: I tried this and the soap scum came right off. I'm completely impressed and no coughing from all the chemicals in cleaners. Never buying shower cleaner again. 1 cup each - warm white vinegar (microwave 2 min) + 1c Original Dawn. Spray, leave for 15 min, rinse.
