I've just cleaned mine too! I accidentally spilt syrup on one of my keys! ( I know, end of the world! ) Quickly wiped it up and it seemed fine, but the key started sticking more and more.. So I just clicked up the key with a little force from the bottom, soaked a cotton bud in warm soapy water, squeezed it a bit so it was only damp, and then wiped around under the key. Lifted the flicky bit up and wiped around it, put the key back in place, clicked it down, and it's absolutely perfect! Like nothing happened! Now just need to be more careful.. Thanks for the tips!
