Somewhere in the escape room I have a 'Statmat' which you place on top of a disc, it removes 'static' and does wonders to CD's and DVD's.

All my discs or all my players must be duffers, I've not noticed any improvements, spookily enough.
It was a gift. Maybe I should give it another try and 'run it in' ...
I also have a Russ Andrews 'Silencer' too, which in fairness, does stop the clicks and pops on my AM sets, from light switches, the shower, tumble dryer and the like.
