My Panasonic PT7000u has acquired some dust on the lens since I purchased it about five weeks ago.

Being that this is my first projector, I was curious if it's a good idea to clean the lens? If so, what's the best method? Is it good to dust it off on a regular basis, or try to avoid cleaning as much possible?

Get a camera lens cleaning kit... or just look at it and buy the pieces yourself. they are low cost about 20 bucks and you may all ready have some of the items.

Just be gentle.

I have a super soft some kind of hair or synthetic duster too that I occasionally barely touching the glass, lightly swipe to remove dust if it seems be building up. Shouldn't need the wipes often unless a fingerprint or some kind of smudge and you'd want dust free as possible first anyway.

These type air blasters are good too...just air from the large bulb.

It's amazing how much dust accumulates so quickly on the lens. And my projector has an automatic lens cover. But I never feel like the dust ever detracts from the quality of the image.

My JVC flimsy filter caught a lot of dust in 1,000 hours, and I also ended up cleaning my lamp and prism, but not the lens yet since there is a mechanical cover, using a camera cleaning kit and microfiber.

There is a difference in the brightness afterward; I also ran my lamp at low/standard but the fan on high (altitude) at all time.

Unless the dust is actually having an impact on the picture, I'd leave the lens alone. You'd be amazed at how much dust can build up on the lens and still make absolutely no difference to the picture quality.
