We live in a dirty world where we cannot avoid the dust and debris that soar around the spaces we inhabit— and inevitably landing on the various surfaces around our homes. An unfortunate result of this leads to a buildup of dirt on our electronics, which then need to be cleaned and/or dusted on a regular basis.

Typically, we’d take out a rag and wipe down the shell of our DVD player or LEDsTV screens for a quick cleanup. But since not all surfaces are created equal— take for instance a delicate camera or project lens— wiping the area with a standard cloth might not be the best idea.

So, how do you clean a camera and projector lens without scratching It?

It all depends on what type of dust or grime has built up on your favorite camera or projecting device.

If it’s just a little dusty, you can brush it free and clear with a light camera lens brush or delicate camera tissue paper. Also, consider tearing the lens tissue paper and rolling it up—the fibers from the tissue paper create a micro-brush.

However, if you’re dealing with a smudge that a camera lens brush just won’t fix, you can try using a specialized cleaner with a microfiber cloth. Make sure you wipe the lens in a swirling motion from the center toward the rim.

All in all, if you’re worried about scratching the surface of your product’s lens, you can always take it to a professional to have that peace of mind in knowing it’s being cleaned correctly.
