If you have a compressor, pull the power brick and blow the dust outside on the driveway (you don't want to do it indoors or in the garage). If you don't have a compressor, if you have a vacuum cleaner with a brush attachmet, that works too. I have a DirtDevil with a soft brush and that gets most of it, then I pull them and take them out on the driveway and blow them off with a compressor.
