dirty apple keyboards meets bosh

Lately my apple keyboard was getting a bit hard to work on. Most of the keys had become 'sticky keys' - even though I thought that to be a Windows concept - but which seems only logical after 4 years of heavy duty without one single moment of personal hygiene. So I thought it was time it deserved a treatment.
After a short information round on the net, I discovered that this - see the picture - was a possible solution. In two hours I'll know more about this experiment :-/
