How to get greenish stain from a bathtub?

We have VERY hard water, filled with clorine. The bathtub has a slightly bumpy finish on the bottom. Near the drain, it has turned a greenish color that I can't seem to get rid of. After trying all the things you would automatically think of, I finally left some water and Clorox in the tub overnight. This didn't work either. I'm at a loss!

    Have you tried cleaning it with alcohol? I'd put some gloves on and use a rag (or sponge) and scrub with alcohol. The nail polish remover might work also.

    If you saturate with hydrogen peroxide some cotton balls or tp if that's all you got.

    Then when you have done this, apply to affected stained area and the deeper the stain, the longer you leave it on that spot.

    You can also use peroxide around you sinks edging in kitchen and bathroom or even is a great grout cleanser as well. Same prep for all cleaning projects.

    Do know that you will be grossed out when you do the sealing caulking around the edge around your sinks and around the faucet base as well if you just run it around the edges of sinks faucet base or sealant, watch out foam. It is actually quite gross. Lol happy disgust or cleaning. Lol good luck

    I’m thinking hydrogen peroxide too, but baking soda and vinegar would be another try for me.
