Can anyone recommend a suitable product to do this, the pavioured area

Any of the commercial products that contain ferrous sulphate.

Effective on lawns, but incredibly damaging to paths unless you are
actually trying for a run down derelict rusting concrete jungle look.

There is almost nothing that will get iron stains off concrete.
(at least not without destroying the concrete as well).

Not tried it but this might do the trick

I would be interested in if it works as we have a long north facing path
at the village hall that is permanently damp in winter and grows a
healthy moss, algae and liverwort population that has resisted all
attempts to kill it! It's a slip hazard when wet (ie most of the time)
