Since cleaning all the dust and dirt out of the cracks and crevices of the X is such a pain I decided to try some of this stuff:
It's not expensive at all and I found it works amazingly well. Sure a whole lot better than some tooth brush or Q-Tips that move everything around. Just be patient with it and it all comes right out without leaving any if minimal residue removing all the dust. If there is any gel left behind it's super easy to pick back up and re-apply.
