Hi there,

I wonder if anyone has some experience here. I am confused.
I got a speck of something in my sensor. I googled you tube and so many ways
some even by professional photog.

1. i got a rocket blower, some use this , - should i use this, my brother told me that may be i will blow more of the air containing dust into the camera , making it worse :-(
2. the other method by michael andrews is he has some kind of a stick thing , goes into the sensor - dust aid
3. other people use like a swab stick with alchol
4. send to the experts at the shop

I am so confused. I have never cleaned it before and nervous.
Please give me some insight. which is the correct method?

Thanks much

I love their swabs/fluid and has worked the best for me for cleaning sensors.

Changing lens will put dust there as well and using the blower with the camera mount facing down works very well and you can get a sensor pen which is the easiest way I found with stubborn dust and if the pen and blower do not work I'll wet clean it . And if you feel uncomfortable doing it than you can always send it in to have it done by Canon. Good luck

First, decide how bad the dust is. Is it only a spec or two that's only visible in the sky at small apertures? Then you might not want to bother cleaning it at all since it can easily be removed on the computer. If you've got lots of specs, then try the blower first. It'll get rid of some stuff but might add more. Once that fails, you can try a static-charged brush to lift small particles off.

When it comes to the really stuck on contamination, you'll want a wet cleaning method. Its truly not as scary as it sounds. I recently bought Visible Dust's wet cleaning products and they did a very good job. VDust Plus and some orange swabs are very effective. If you know you have lots of oily contamination, use the smear away and green swabs first, then follow up with the VDust Plus. Remember that keeping your sensor clean is a never ending job, even if you never change lenses. All you can do is keep it to a minimum.

I wouldn't bother having Canon or a shop clean it. My camera's last and only trip to Canon for a cleaning resulted in the removal of some dust and the application of some really stuck-on spots. They're not going to take the time and care to check it the way you will.

Also, get a sensor viewing loupe. It makes it much easier to see the spots so you'll spend less time doing the f/22 test.

does the spot appear in your photo's (take a picture at an apeture of f22 of a blank surface) or only in the viewfinder.

if it appears in the viewfinder and not on the picture, it's sitting on your mirror, focusing screen or superimpose screen.

if it's in the picture it's on your sensor.

This is a good information site, it gives you all the different methods of cleaning and the process of identifying a dirt on the sensor

When you look at an image on the LCD, do you see the spots, or is it in your viewfinder? I have not cleaned my sensor on my 5D2 once. But the viewfinder is a mess. I have to open up the cavity, as if I am cleaning it (set it to clean), and I blow up toward the viewfinder and blow the junk out and it works most of the time. If you can look at the sensor with the cavity open and set to clean and see dust, then yes, get the sensor swabs and Eclipse solution and do a couple of swipes for $80, and you'll have the swabs for another 11 times. But if there is nothing you can see on the sensor, it's probably the mirror or the dust in the viewfinder.

These are just some of the products for cleaning your sensor and they come in different price ranges so don't be afraid to learn how to do it your self and also here is the Internet sight that got me started on how to do it myself.

Purchased my kit from Copper Hill Images and have had good fortune with it.

Another vote for Copperhill... I've been using their systems since my original digital rebel. I never leave my house for an important event without swabbing my sensors. It's only scary the first time. After you do it and realize you can't kill your camera by following directions, you'll be fine.

Hi everyone
Thanks so much for your suggestions.
I only have one spect of something on the sensor. I always see this thing on the sky type picture.

Nobody seems to have mentioned the rocket blower thing.
Should I just go ahead and give it a few blows to see if this spect goes away ? My feeling is that the rest of the sensor is clean.

use the blower first, then look at using a sensor clear pen, dust-aid or static brush, and as a last resort wet clean.
