I mean... I just use a vacuum cleaner on the removable case grills and bottom of the case, and then a photographers sensor cleaner (the blow bubble thing) for around caps and chips, and an old make-up brush (never used on make-up as you won't want residues on things) on fan blades and heat sink grills.
I'm not trying for perfect, it doesn't have to look like new. I only try and shift the majority so that cooling works. That last 1% is also going to be back there in a day or two, it's clearing 99% of the dust that matters.
