 Mix liquid ammonia concentrate (NH4-OH) + cold (!) water in a bucket;
 hold your keyboard with them keys down (!) above the bucket;
 
 use a softly scrubbing brush (horse hair = less sqirting) wetted w/ mixture
 and brush the keys from underneath, moving brush softly along their gaps;
 
 keep the keyboard upside down, so the cleaning agent will not enter any
 keyboard contact, and put the keyboard on a warm place in order to get all
 water w/ ammonia completely evaporated.
 
 (Ammonia itself won't leave any residue.)


I just use 90% pure (or better) isopropyl alcohol undiluted, and a soft, 
lint-free cloth.  Just spray on.  Cleans all the crud off, and evaporates 
quickly.  Most pharmacies carry it.  Don't mistakenly buy rubbing alcohol.  It 
has oil in it.  It's made for massage.  You don't want that.
