Copper sulphate powders

[amin36]

Hey guys

One of my customurs used copper sulphate to beat algae and he used too much of it.after understanding what a mistake he had done he completely drained the water but after that powders of copper sulphate are sticking to the tiles and now we have copper sulphate scales.so how should i do clean that?
one thing came to mind is acid washing.anyone any opinion?

Maybe CLR or TileLab sulfamic acid cleaner.

Do some research to make sure that whatever product you choose is suitable for your project.

Do you have a picture of the scale?

Is the whole pool tiled?
