How to clean my laser mouse sensor from dust.

How to clean my R.A.T TE mouse sensor.
My table gets very dusty, and the sensors are deep in some cave-like hole and have no plastic to stop dust getting in. This causes it to randomly freeze for a second or two on one axis

Inside I can see two tiny dome-shaped objects, one a-bit behind, the other a-bit to the right of the center of the opening, probably different movement axes which seem to be transparent, the opening is like 2-3mm across, so I can't reach in anything to clean it, should I try vacuuming it? Can I rip anything out?

Buy a can of compressed air and use the thin nozzle attachment.

Any chance of it getting dust somewhere else where it shouldn't be though? Also I don't think my parent have any, and I'm in a rural area and I don't feel like annoying my parent even more, so do you think a vacuum can damage anything?
