my left ctrl key has been unresponsive and getting dodgy for a while, till it finally screwed up, was due to liquid spillage like a beer or cider too many 
any ideas how to sort it, i would hate to have to buy another keyboard just for one key, i have tried putting ipa into the switch with the key cap off and a make up brush with some bristles into the switch with the ipa doesnt seem to work but its got power as the led works, just does nothing when i press it.
any ideas?
