G'Day,
I am told iron shellate stains are difficult if not impossible to remove from pavers. Any advice Please?

What have you tried to date? Oxalic acid may help.

You could also try Citric Acid, But as with Oxalic Acid you really can't spot clean so will need to do the whole area/surface or you will end up with a poka-dot type paving. I would only use either of the above acids on white concrete though, you might have problems with coloured surfaces.
