If you are looking to clean your camera's sensor, there is a lot to know. The key is knowing what not to do, as well as knowing how to properly care for your camera. We'll break down each step in this article so that you can understand how best to clean your camera without damaging it or causing other problems later on.
turn off the camera
It’s imperative to turn the camera off before you start cleaning it. This is because most sensors have separate electronics, and you don’t want to risk damaging them. You also need to remove your lens from the camera body, because otherwise you could damage it when working with other parts of your camera.
Next up is looking at your sensor for any obvious problems like dust or smudges on top of it (you can do this by peering through the viewfinder). If there are no obvious issues then it's time for step three: inspecting each individual pixel on the surface of your image sensor for damage or dirt build-up.*
remove the lens and have a look at the sensor
If you've got a DSLR, this is usually pretty easy to do. Just remove the lens by unscrewing it and pulling it out. If there are any visible particles on the sensor, they'll be obvious now that you've removed the lens.
If your camera has a mirror or prism in front of its sensor, look for dust or smudges on that as well (if you can see it).
rule out problems with the lens - put another lens on and see if you still have the problem
If you have more than one lens, try using a different one. If the problem persists, it’s likely that your lens needs to be cleaned.
If you don't have another lens to test with, consider the possibility that it's the camera itself that is causing the issue.
if you have an air puffer, give the inside of the lens and body a quick burst to remove any dust that may be on your sensor.

Blow off any dust using a blower in a circular motion, starting from one side of the camera and moving out towards other corners. Do not blow towards yourself or directly onto your sensor; this could damage it!
use a visible light while taking pictures of something white
Make sure your camera is on a tripod or some other steady surface to keep it from moving while taking the picture.
Use a remote shutter release if you have one, otherwise use the self-timer or press on the button with your finger as gently and evenly possible.
Take a picture of something white (like a white wall). This will let you see any particles that were left behind after cleaning the sensor.
look closely at your photos of the white object to see whether any particles are visible.
Look closely at your photos of the white object to see whether any particles are visible. In most cameras, the sensor is on the back of the camera and will be covered by a protective cover or filter when not in use. Make sure that this cover is removed and that there is no dust or moisture on it.
It's also important to note that there will be an inverted image reversal effect when taking pictures through a viewfinder: everything you see through it will come out as if it were being viewed from inside out (i.e., black becomes white). The lens sits directly in front of where your eye would be looking through said viewfinder so make sure it's clean too!
do not touch your camera's sensor.
Don't touch it with your fingers, and don't use a cloth that's been used on other things. The sensor is extremely sensitive to dust and can get scratched easily. The best way to clean a camera sensor is by using an air blower, which will blow away any dust particles that have accumulated on the surface of your camera.
If you do use an air blower, be sure not to hold it too close to your lens as this could cause damage. Also be careful not spraying too much force at once; if you're blowing hard enough for it sound like a jet engine, then perhaps think twice before continuing!
Before cleaning a camera's sensor, there are some steps to take first
Before you begin cleaning a camera's sensor, there are some steps to take first. First and foremost, turn off your camera. Next, remove the lens from your camera body if possible and look at the sensor through it. If you see any dust or dirt on it, that may indicate that there's something wrong with your lens and not just your sensor. If so, try swapping lenses (or removing them) and see if you still have the problem when using another one!
The above cleaning steps are designed to ensure that you don't damage your camera by doing unnecessary or careless cleaning. In the end, if you still have problems with dust on your sensor, it may be time for a professional clean.
