    or if you don't want to use harsh chemicals, try baking soda and spray with vinegar. It worked very well for my shower.

    Get some CLR found at a big box store. You can saturate a towel and lay it on the calcium deposit. I'd start with using full strength vinegar first as that works well also and is cheaper. What you don't want to do is use anything that will scratch or score the finish on your tub.

    I use Sanivac, a concentrated cleaner, that removes soap scum, water spots,bathtub rings & scale, rust & mildew. It is relatively inexpensive and is manufactured in San Antonio, Tx. You can see more info at I even use it to remove the cloudy film on my fine crystal. I was not aware of 'hard water' until I moved to San Antonio. Now I know why Sanivac came to be!
