Diluted Isopropyl alcohol on a cloth is the best for removing oils and grease. Try to buy it pre-diluted or dilute it yourself using demineralised water. Never use it non-diluted as the alcohol can damage the plastic. 50% is probably the maximum safe mix, 30% Isopropyl alcohol or less on more sensitive surfaces.
Don't use a dishwasher unless you're prepared to lose the Dell Inspiron Keyboard
. Every model is different and some have exposed electircal surfaces that if not dried perfectly will short circuit the keyboard.
With modern keyboards like Dell Inspiron Keyboard
you HAVE to remove the electronic components before immersing the mechanical parts in water. I've found Microsoft boards very easy to disassemble; Logitech much more difficult. I don't have a dishwasher, but a good soaking in hot water /dish liquid seems to work well. rinse well, then dry outdoors. I would like to get more feedback about using silicone spray--I always assumed this might attract more dust?
