Rust Stain on New Plaster

Try taking it up to shock level. That works for leaf tannins and doesn't require scrubbing. It takes about 6 hours to remove the really bad stains.

This will make the staining worse if it is metal. Chlorine forces metal out of the water and on to the surface of the pool.

Thanks for the suggestions. I had read that vitamin C works on some stains, but I wasn't sure about rust. I'll try that first (since I have some here at home) and if that doesn't work, I'll try the eraser.

Thanks again.
