Question about Sharp Pro PG-D120U Multimedia Projector
You probably don't need to. I know you may see what looks like a lot of dust, but unless it's completely covered, that dust on the lens has very little effect on your projected picture. If it is really bad, you can try to open it up and clean the lens with a lint-free lens cleaning tissue (NOT FACIAL TISSUE) and a couple of drops of distilled water (or lens cleaning liquid). But you best bet, if it's really dirty is to take it to a service facility.
