heyhey! I've been using my U2 for a while now, and every now and then I've been using a cloth to try and reach in to wipe some of the dust off the blades of the fans. Thing is, it's not very effective and I usually don't manage to get rid of all of the dust.

Any idea how to completely take apart the U2 fan for cleaning without damaging the wires? (sorry I'm quite bad at this haha)
