Body: Cleaning your camera body is like cleaning almost any other gadget—a very slightly damp towel will do the trick. (Though be gentle around openings, since point-and-shoot camera guts lurk awfully close to the surface, and any intruding water can wreak serious havoc.)

Lenses: Lenses are dirt magnets, and if they're dirty, you simply don't get good pictures. They're also delicate and expensive, so you can't just reach in there with a paper towel and be done with it. Lens cleaning kits are available at every camera store, and include a light cleaning solution and microfiber cloth. These are safe bets, but don't spend more than $15 bucks on them. Lens pens also work, but they're a riskier proposition—there's such a limited cleaning surface on those things, and I always get the sense that after a few uses, the cleaning element has been sort of tainted.

Again, though, stay safe with this one: Buy a microfiber cloth, and simply rub the lens with a circular motion until all visible smudges are gone. Never apply too much pressure—any dust or dirt on the lens can get picked up in your cloth and scratch your lens—and fold/refold your cloth to ensure you're using a fresh surface at least once during a lens cleaning.

Two small notes on lenses: Don't forget the clean the rear glass on any DSLR lens. There's a lot less surface area there, and since it spends most of its time inside the camera or a locking lens cover it probably won't be as dirty, so this should take much effort. And if you can, treat each of your DSLR lenses to a UV filter. While this is called a filter, it only block light that humans can't naturally see, meaning that in most photos, the effect will be generally unnoticeable. (More on that here) Point is, you don't have much to lose by buying one of the dirt-cheap filters, and it will provide a layer of transparent protection from dirt and scratches over your lenses at all times. And since they're flat and thin, they're easier to clean than convex lenses.

UPDATE: I've gotten a couple of emails from photo pros about this, and I think it bears mentioning: Before rubbing your lenses, it's good practice to blast them with a little air. Air pumps (like the one mentioned in the following subsection) and canned air will do the job, as will, in a bind, your lungs. The thinking here is that you should remove any potentially abrasive particles from the lens before rubbing it, so as not to drag them around, causing permanent damage. —Thanks, Jody and Ned!

Sensors: Point-and-shoot and bridge camera users don't have to worry about this, but DSLR users, who provide a chance for dirty to enter their camera bodies every time they change a lens, may need to clean a sensor one day. It's not as scary as it sounds!

First of all, you'll never have to actually clean a sensor, since DSLR sensors all have some manner of filter, either IR or UV, built in. But still, the surface is delicate, so you'll want to be cautious. Most cameras include some kind of sensor-cleaning function in their software; since most sensor taint is comprised of a stray speck of dust or two, a quick, severe vibration will usually do the trick.

If that doesn't work, and your photos are showing persistent, faded, unmoving spots in every photo, it's time for phase II: air. For this, I defer to Ken Rockwell:

After 17,000 shots I finally got a speck on my D70. Remember I also change lenses a lot. The Shop Vac wasn't enough. This time I used an ear syringe (blower bulb) from the drug store which you can get here. I put the D70 on BULB and pounded the bulb with my fist to create a jarring blast of air. That worked.

Rockwell advises to use an ear syringe; I'd say go with a purpose-design lens blower, since they're still only about $10, and you'll get better results without running the risk of pulverizing your DSLR's guts while trying to get muscle enough airflow through a hard rubber earwax remover.

Beyond built-in sensor cleaning and a few blasts of air, there are plenty more methods for cleaning a sensor, but they're all risky to varying degrees. Unless you're supremely confident (and careful) it may be best to leave this one to the guys are your local camera shop, assuming you still have one. A ruined sensor, in most cases, is a ruined camera, so tread carefully.
