Thanks for replying.
Yeah, I know that it's been devalued. Still, it does a decent job, even at games, provided it stays cooled (although it gets blown out of the water by today's units). Either way, people are still paying at least three hundred for it.
I just want to generally clean the keyboard, as it hasn't had a comprehensive clean under the keys in literally 5 years. In the few keys I've lifted up, it's pretty disgusting. Just a personal preference to not disservice a buyer, even if they may never look under there. If I really wanted to, I could put "Cleaned keyboard" in the product details or something.
As for the wash argument, you can detach the keyboard from the chassis, as well as from the front panel; theoretically, no electronics would get damaged (unless there's something that holds a charge in the actual keyboard itself). My main worry then would be the detachment of the silicon nubs.
For actually removing the keys, do you know how to remove the large keys? My attempts at the large keys causes the clips for the underlying metal bar to get damaged, leading to replacement.
