The prongs for the top picnic table are on the left hand side as with the standard keys. Remove the bar by putting the tool in the top edge and running it clockwise down the right side. The Enter key has two picnic tables and a metal stabilising bar. may be the same but I didn't try them myself). After the metal bar is detached it can be removed as above. The prongs on the Delete key are on the top-right and top-left and the bar on the bottom. This should snap the bar out of its place. To remove the Delete key slide the tool in flat at the right hand edge of the key and run it up and across the top to the top-left corner. For the function keys you probably need to use the tool for both prongs and note that F6 (num lock) has the prongs on the right hand side. Then lift the whole key up and to the right and it should come cleanly off with the picnic table attached. Once it's out, pull the key down from the top-right corner and wiggle until the left hand side of the key is detached.

To remove the 'normal' keys, use a thin, flat tool such as a pair of tweezers or a small screwdriver to get under the key at the bottom-left corner and push the prong out of its hole. The bar slides under a hook along the right side. The prongs fit into two holes on the frame: one top-left and the other bottom-left. This has two prongs on the left and a bar on the right to attach it to the metal frame. Most keys are attached with the same mechanism: a kind of 'picnic table' gizmo attaches them to a metal frame on the laptop. There don't seem to be any good tutorials online for removing and cleaning MacBook keys and hence this page. Luckily, about a week later it fired up again and everything was still there so my advice to anyone who does the same is to leave the machine for a week before trying to turn it on again as the moisture may still be inside.

When I tried to switch it on again I was confronted with the dreaded flashing question mark and the guys at the Mac shop said I'd fried my hard-drive.

About halfway through my summer project I managed to spill a half pint of orange squash on the keyboard of my beloved MacBook.
