Never had to do that (don't have one) but, empty it out, vacuum it if you have to then get a trusty old cloth and start wiping with rubbing alcohol. Please do it in a well-ventilated area.
I did this to my 4-pans and 15-pan as they were pre-loved. Cleaned them a real treat.

I'm a bit like that too. Hee hee. But dust has a way of sneaking in. I have a drawer in my bathroom where I keep my most used things and sometimes stray hair shavings make its way into it! And they aren't even my shavings!
LOL well yeah bizzarr things manage to find their way into just about anything. I'm just thankful I've kept the dog hair out! That stuff gets everywhere!!
Give the Clorox wipes a try. I smeared some e/s & pigments around the inside of mine (since it's never dirtry) and tried that out. It works pretty good.
