Rubber Contact Strip Preservation

Rubber Contact Strip Preservation

2015-09-21 by turboswami@gmail.com

Hello All,


I recently opened up my Korg to do some routine cleaning of the key contacts, in preparation for an upcoming studio session. In addition to the regular Q-Tip/rubbing alcohol cleaning, I tried the pencil eraser trick on the metal contacts, as someone recommended on this forum. I also purchased a small vial of the CaiCote 44 contact coating, as was recommended on here a while back.


My concern came as I was delicately removing the rubber contact strips from their placeholders -- those small plunger portions are so fragile and are beginning to crack and chip off in places. I realize all rubber ages in this way, and a degree of dry rot is expected after 35 years, but I was wondering if anyone has any recommendations on preserving these rubber strips from further drying/cracking. I'd like for this machine to last another 35 years, if possible... But I can imagine these strips, eventually, being unable to be safely removed at this rate, without those small "mushroom" clip mechanisms simply tearing right off.

or else use formula 303 aerospace protectant... though it's better to start using it when the rubber is 'newly' manufactured - it's a fantastic proven product for all kinds of rubbers and plastics - like the butyl rubber surrounds of bass drivers on loudspeakers etc...
