8. Don't fix it if it aint broke. Don't clean it if it aint dirty.

There might be a little dust in there, dust gets everywhere and generally doesn't cause a problem. There really won't be anything much to clean, so just clean what you can get to.

Trying to take it apart without a damned good reason (like it doesn't work and won't get any worse if you drop the top and destroy the innards completely) seems like a losing game. If you're working off nervous energy through cleaning, consider moving it out from the wall and cleaning under it, that's where you'll find the lost paring knives and science projects.
