Hi Midiboxers,
i asked my electronic dealer of trust for something to clean my boards.
He advised me this:
"PCC" from Kontakt Chemie.
It was quiet expensive 12€/200ml
But this stuff is really amazing and very, very fertile.
Unfortunately i have cleand all my boards now so i can not show
you some "before/after" pictures :smile: I will post some later.
Best regards
Marxon
