What is the best way to clean the plastic switches on large receivers? One speciment I have sounds like "Rauchfilter" is almost never fully disconected. Bloated bass and high frequency attenuation.
All advices are welcome, thank you.

Hi Massimo!
Thank you for advice. I used wd40 contact cleaner.
I pushed the plastic nosle inside the switch and soaked them all with cleaner. It did get better.. Bass is better now, but mid/high still sounds little coloured and congested. I will repeat the procedure few times..

I don't have good experiences with wd40 ...
However the sound gets worse for a while ... until it dries
