Hi-- first blow off any loose dust/dirt with blower and then you can use any rapidly evaporating cleaning solution ( window cleaning solution with amonia is OK ) to clean both sides. Do not use acetone ! ( will attack plastic ) . Benzine is also unsutable . Do not touch with fingers : remove with tweeezers and insert back with tweezers.
