    Stain on concrete

    Anyone have an idea of what will remove this stain? I guess it is coming from the flagstone around my pool.

    I'm sorry, I can't see what area you're looking at as a stain? Can you circle it or something?

    Love your pool deck surface otherwise though

    In the relief cut and extending onto the grate.

    I think some orange paint for the grate and the rest of the reliefs cuts would do the trick! Why fight nature when you can join it? (I'm kidding, but who knows?)

    That looks like rust/iron stain. Some type of acid will clean it if it is rust. Vinegar, ascorbic acid, muriatic acid diluted 2 or 3 to 1, etc. Always add acid to water.

    I suspect that it might come back if something metal is rusting. Possibly some rebar or framing iron.

    Looks rusty at the top near that blue tile.

    Looks like rusty water is seeping out and running down the control joint.
