My IBM Model M Caps Lock key sticky

[yuliadobe]

Hello,

Recently I purchased a IBM Model M (made by IBM). It came in a brand new condition. For some reason, the Caps Lock key becomes sticky (as in if I put my finger on top of it to touch it, after a few seconds, the key cap feels sticky).

I also noticed that the center of the Caps Lock key is "shinier" than that of other keys as if there is a layer of coating (or is devoid of a layer of coating). Does anyone else experience this? If so how did you clean your key to make it feel "smooth" like the other keys?

Thanks,

Well, since this is posted in the Geekhack Refugee Camp subforum GHETTO I can ONLY guess.

Anyway I like Simple Green. I plan on doing a cleaning tutorial (I was RUDELY interrupted at GH doing mine) but here are some preview pics...

I don't think it's dirty since it was purchased brand new. Maybe because it was in the box inside a styrofoam for 17+ years the styrofoam made it sticky..
