Clean with a damp microfiber cloth with a bit of washing up liquid and then buff lightly with a dry MF cloth.”
I use Fellowes cleaning spray and Fellowes screen protector.
These are used by proffesionals for lenses,screens and any other optical surfaces needing a complete clean.
I source mine on e-bay and got the two canisters for under £10-if you buy from a proffesional outlet you can pay around £18 or so per can!
