The only SPOT REMOVER you may ever need ~ Mix one part Dawn dish washing liquid with two parts hydrogen peroxide; pour or spray it directly on the stain, and watch it disappear like MAGIC....will need to try this out
My bathtub has never been whiter!! Works great on glass shower doors too- no more soap residue! Martha Stewart's Tub Scrub--works better than any other cleaning product to get off hard water and soap residue. 1 cup baking soda, 1 teaspoon dish soap, enough water to make a paste.
