    Copper is seldom naturally present in a water supply, and usually results from the corrosion of copper plumbing. Signs of copper contamination in a water supply include: Blue or green stains on showers, sinks, and other plumbing fixtures.

    To clean

    Make up a paste. Use equal quantities of cream of tartar and baking soda (bicarbonate of soda). ...

    Spread the paste across the blue-green stain. Rub in well.

    Leave the paste to work on the stain. About half an hour should be sufficient time for it to do its cleaning job.

    Rinse off the paste.

      I was afraid it would ruin the glazing on tub, but will try. Had a problem with soft water system thought blue stain was the result of their chemical solution to clogged system earlier this year.

    I've had good results at my client's home removing the blue with Dollar Tree Awesome Orange in the half gallon. I pour it on, let it sit 5 mins then rinse off and scrub off any remaining with a long-handled bath pouf from the dollar tree.

    It’s probably copper or brass stains from your water. I would try CLR (calcium, lime, rust remover). You can buy it at Walmart, Home Depot, etc. You can also try a paste of baking soda, dish soap and hydrogen peroxide: spread on, let sit, scrub and rinse. Or make a mixture of dish soap and vinegar: spray on, let sit, scrub and rinse. Let us tknow what works!
