@Ripster: Thanks there are some great guides. But none describes the "Enter" key of the german layout. It is a bit different formed and I have no idea what the savest way is to remove it. Also, are the stabilizers ?
For the A key: lol the sound is a bit like that but with a higher pitch.
@edit: I have a Filco Otaku version.. I wonder if I can put all the keys into the dishwasher to clean them?
Also: is it safe to clean out everything under the keys with a "compressor" ?
