    clorine puck stained my new plaster...

    Tried a vitamin c tablet, that made it worse. The plaster is 5 weeks old. I am not fond of the floaty right now. Any suggestions?

    I don't understand, did the puck fall out of the floater somehow?

    The chlorine concentration in the immediate area of the floater is very high. If it sits too long in one place, especially somewhere shallow, it can cause damage.

    It is a bit of a long shot, but you might as well try holding a vitamin C tablet against the dark spot for 30 seconds and see if that improves the appearance around the tablet or not. High FC levels from the floater could have caused iron staining, which vitamin C tablets can remove.

    Jason,
    That dark circle in the center of the damage WAS a vit. C tablet. So I suspect a different approach is needed. I just don't know what it is- fine grit sandpaper, perhaps?

    You can try a pumice stone block, which will have about the same effect as sandpaper but is easier to use underwater.

    I had a customer so the samething to his black plaster, he had luck by draining the water down to where he did a light acid wash and removed it.

    Re: clorine puck stained my new plaster...

    That's doable. What concentration on the acid(how to dilute the acid?)
    Thanks for the idea..

    220 fine grit sandpaper, and 20 minutes of sanding. It's as good as new!
