Someone at Neogaf posted how to degloss his DS:
I do highly recommend working with a lamp if you decide to do this. You see to wipe off the dust and look at it at an angle to see where it's still slightly glossy. Once you work off the gloss it's a different kind of plastic underneath and scratches don't show.
For a last couple notes, I used one of those fluffy-feeling kind of paper towels to brush dust off the file now and then. It got it off best and would grab on the grit to let me know how much is left on the part of the file I was using.
Also, after you wipe off the dust, there is still going to be a very thin layer on the top that will make it look lighter. Just use your hand oil (it will soak up your hands dry) and when you rub it you should see the superfine dust form into clumps, it seems bluejeans are best for wiping this off, then use a finer cloth to buff it more.
I decided I'd leave the sides smooth and shiny because it looks kind of cool, it'll make sliding the power and volume easier and it'd be a pain to work on
