Be careful saying alcohol. Several different types, isopropyl, denatured, straight, etc. Soap and water normally work fine, just make sure you use some air to blow them dry or let them dry overnight. Would not suggest using anything very strong on the pc board contacts as you may ruin them, and then it's all over but the weeping and the wailing. As for the one thread reply about repair shops, don't condemn repairs in general because of one bad apple. I happen to take great pride in my work and try my best to get it turned around as quickly as possible, especially for a working pro. I also make sure I don't have any screws or parts left over and do a thorough check before it leaves the bench. There is a group called MITA that certifies techs. I am a certified MITA tech and a Master Certified Tech for one manufacturer and also certified by several major manufacturers who oversee the work you do on a regular basis.

The only Korg who's keybed I have looked at is the MS-20 so it's probably different than yours. If it's like the keybeds (mfg. by Mitsubishi) on the Korg Mono/Poly, Memorymoog and OB-8 take a look here for cleaning instructions: http://www.oldcrows.net/~oldcrow/synth/korg/polysix/keyclean.html Scott Rider is a brillian man but I would take slight issue with his suggestion to use an eraser on the contacts, this should not be necessary. You will want to use it (VERY GENTLY) on the black contact that is inside the rubber cup though and only a few gentle swipes. Hate to state the obvious but make sure you tet everything prior to buttoning it up. I usually use alcohol followed by a contact enhancer but the latter is not required.
