just take it apart, let it dry and clean it with 70% medical alcohol [don't drink it please], that works, and if you use a laptop, do the same to all the inside parts like the motherboard, 2.5 inch harddisk, floppy drive and dvd/cd player (which have very itty bitty tiny screws) and also all the connectors, just know absolutely very certain which screw gets in which hole, when ya assemble all together again ... so very easy to do, if your short of cash, just need lots of patience SMILE ... i have cleaned many laptops of the dutch army which were messed up with cola, mud and greasy stuff have a nice day Harmen
