well water stain removal

[John T.]

I have a shower base that has stains from the well water.   The water had some sulfer smell to it whixh sounds likes it may have also had iron from what i read.  Tts a orange brown color.  Tried lemon juice and vinegar something i read online and it did nothing.  Any help greatly appreciated.  Not sure what shower base is made of almost looks likes quartz.
