I’ll be straight with you: I used to think camera maintenance was something you only worried about when something broke. I’d wipe down a lens with my shirt, blow on the sensor like it was an old Nintendo cartridge, and call it good. Then I spent a weekend shooting in Rocky Mountain National Park and spent three hours in Lightroom cloning out dust spots that I could have prevented in twenty minutes at home. That was the wake-up call I needed.

In this Tony & Chelsea Northrup tutorial, Watch the full tutorial on YouTube, Tony walks through the full maintenance routine he uses on his camera, lenses, and tripod. It’s practical, unglamorous, and exactly the kind of thing most photography channels skip because it doesn’t sell excitement. What I like about his approach is that it maps to real shooting situations, not ideal lab conditions. Here’s how I’d walk you through it.

Step 1: Check and Install Firmware Updates (Carefully)

Checking manufacturer support page for new firmware Checking manufacturer support page for new firmware Start at your camera manufacturer’s support page and look up your specific camera and lens models. If there’s newer firmware than what you’re running, don’t install it immediately. Tony’s rule is to wait at least a week after a firmware release before updating. The reason is practical: manufacturers occasionally push updates that introduce new bugs, then quietly pull them. Let other people find those problems first. Once the version has been out for a week or two without noise in the forums, it’s reasonably safe to install. This applies to lenses too, especially newer autofocus lenses that receive performance tuning updates.

Step 2: Recustomize Your Camera Settings

Your shooting style drifts over time. The custom button assignments and saved menu configurations you set up eighteen months ago probably don’t match how you actually shoot today. Tony recommends periodically going through your custom settings, whether that’s the “My Menu” shortcut list or the custom mode dial positions, and rebuilding them based on your current workflow. It takes maybe fifteen minutes, but it can meaningfully speed up how you work in the field. If you’ve never set up custom modes at all, that’s the first thing to fix before your next shoot.

Step 3: First Pass Sensor Cleaning with a Blower

No breathing on it. A proper rubber bulb blower is cheap, safe, and should be in every camera bag permanently. Tony’s technique is to hold the camera with the mount facing down and direct air from the center of the sensor toward the edges, so you’re pushing dust out rather than redistributing it. Many cameras also have a built-in sensor shake function, usually buried under the wrench or tool menu icon. If yours does, enable the option that runs it automatically every time the camera powers down. Neither of these methods eliminates dust entirely, but they reduce how often you need to do a full manual clean.

Step 4: Test for Dust Before a Big Shoot

Point your camera at a plain white wall or overcast sky, switch to aperture priority, and dial in the smallest aperture your lens allows, something like f/16 or f/22. Then either record a short video or just pan the camera slowly around while watching the screen. Any sensor dust will show up as small dark spots that stay fixed in the frame while the background moves behind them. The higher the f-stop, the more visible the dust becomes, which is exactly what you want for this test. If you see spots, clean before you shoot. Discovering them at f/2.8 on your hero shots the night before delivery is a much worse situation.

Step 5: Manual Sensor Swabbing

Tony’s honest that this makes a lot of photographers nervous, but it’s a learnable skill and not as risky as it sounds if you use the right tools and take your time. You’ll need sensor cleaning swabs sized for your sensor format and the appropriate cleaning fluid. The general motion is a single slow pass across the sensor in one direction, then flip the swab and do a single pass back. Don’t scrub. Don’t reuse swabs. Retest with the white wall method afterward. If you’re still not comfortable doing this yourself, sending it to a manufacturer service center is a valid option, though Tony points out you’ll be without your camera and they’re likely doing the same process you would.

Step 6: Brush Out the Camera Body Crevices

Grit that collects in the seams around buttons, dials, and the lens mount eventually works its way deeper into the camera. A soft-bristle brush, the same kind sold for sensor cleaning, handles this well. Run it through every seam and crevice on the body and lens barrel on a regular basis. It takes two minutes and it’s genuinely preventive maintenance, not just cosmetic.

Step 7: Cover the Hot Shoe

The hot shoe on top of your camera has exposed electrical contacts designed to communicate with a flash. Left uncovered, those contacts can corrode from humidity or moisture and potentially cause a short. Hot shoe covers are tiny, cost almost nothing, and your camera likely came with one that you threw in a drawer. Fish it out and put it on any time you’re shooting without a flash attached.

What I’d Add: Budget Gear Needs This Even More

Higher-end cameras tend to have better weather sealing, tighter tolerances, and more durable materials. Budget bodies and lenses, the ones I spend most of my time testing, are built to a price and they pick up dirt faster, the seals wear sooner, and the contacts are less forgiving. If anything, if you’re shooting with a $400 kit like I started with, a consistent maintenance routine matters more, not less. I clean my budget bodies more often than any flagship I’ve tested because they need it. Maintenance is one of the cheapest ways to extend the life of gear you can’t afford to replace.

The single most important thing this tutorial drove home for me is that maintenance is just a calendar item, not a reaction to something going wrong. Build the sensor check and firmware review into the start of every major project, run the exterior brush-down after any outdoor shoot, and the worst-case scenarios become rare instead of routine.
