Seeking advice for removing stain from coping stone

[ArchaeoChick]

About a month ago, we noticed splotchy orange stains on our new pool’s lueder coping stone. The only thing I can think of that could have caused it was my husband often leaving pool cleaning tools (a long aluminum pole, nylon bristle brush, and net w/ plastic hoop) on the stones, and a tool somehow stained the stone.

The orange color makes me think it’s likely rust, but I can’t think of any components of the cleaning tools that have iron/would produce rust staining. Scrubbing the stain with Dawn dish soap (my usual go-to for testing stain removal) did nothing.

Does anyone have advice on how to remove this staining or what may have caused it? I feel so upset with myself that we spent a ton of money on a beautiful pool and already have ugly stains because of our own carelessness.

If it is iron (rust), take a bunch of vitamin C pills in a sock, crush them up, then using water, rub the sock on the stains. If they are rust, they will lift in 3-5 minutes. Rub and keep a bit of water flowing...

I’ll give it a try! Are you referring to something like chewable vitamin C tablets I can get at a pharmacy? Or any specific product/brand?

Yep, maybe not chewables, just Vitamin C hard tablets...ingredients will be Ascorbic Acid...Vitamin C. There may be other ingredients, doesn't matter.

Gotcha! Thanks, I’m going to try it! Hopefully this is indeed rust so that vitamin C will resolve it.
