How to get water stains off cultured marble whirlpool tub?

I have water stains from the jets and the marble is discolored. We have hard water. I have tried everything from vinegar, soda, lemon juice, denture tablets, Bar Keeper Friend and every other cleaner on the market. I've researched everything on-line and Pinterest but nothing works!

    Sometimes the hard water actually etches into those plastic marble tubs. Also the manufacturers warranty is only good for 5 years because hot water actually assist in breaking down the resin. A very secret manufacturing flaw. If you have tried all safe products made for acrylic tubs/cultered marble, it's probably etched. If you know the manufacturer of it, I'd call to see what they recommend.
