Alcohol is not the best option to sanitize. Alcohol could also erase the letters/numbers/symbols from your keys. There are commercial products ( depends in which country you live ) that do a much better job than alcohol. You could ask you family doctor, your pharmacist or your local store ( specialized in cleaning products ). For the dust use a regular vacuum cleaner. Use it often but be careful because these beasts can suck your keys away.
This is a shocker ! Whilst I just tip it up, give it a smack and out comes all the fag ash and dead flies, I read on the net that somebody said they put the wretched thing in the washing machine ! God almighty - why not a sandblaster ?
Actually deionized water could be used to wash an electrical device (unplugged of course ). Then you have to 100% dry the device before use. These procedures could damage the device or you...so you should not try them.
My keyboard is pretty "particlesbetweenthekeys"-proof, because they're so close together (logitech illuminated. great board! ). So just some dust on top.
For those who are hard on their keyboards dirt and dust wise the rubber encase flexible keyboards would be ideal. A quick wipe with a damp cloth and its clean.
My Keyboard is full of Dandruff and tiny skin flakes (because i am suffering from Minor Psoriasis) ...
I usually turn mine over and tap out the cigarette ashes every month. Other than that and cleaning the keys when I can't see the letters, I don't mess with it. I wish the computers today were as reliable.
I recently heard about a study that looked at how clean various surfaces were in hospitals. It turned out that bathrooms (e.g. bathroom doorknobs) were the cleanest because they get cleaned most frequently and thoroughly because people think of them as dirty. The dirtiest (most bacteria infested) surfaces were phone buttons, tv remotes and other items that different people handle the most but that often go unnoticed by the cleaning staff (if you've ever been hospitalized, do you remember the cleaning lady/dude come into your room and wipe down the remote control?). A few days ago I bought a can of soft green goo called Cyber Clean that's meant for cleaning keyboards -- hope it works. I also use compressed air to blow some of the dirty out, a regular vacuum clean to suck dirt out, and wipes with isopropyl alcohol to kill bacteria. I'm not germaphobic in general, just with keyboards.
