Try using a lens blower on the sensor or shoot at a lower stop.

Lens blower will fuck it up!
You have to leave it to service to get it clean!

Is the only solution to leave it to service?

You can buy products to do it yourself, but they usually void your warranty.

Doesn't 40D have a self cleaning sensor?

yes but apparently it can't handle this.. I don't know why, I've been cleaning the lens really good and the UV filter aswell, its not those..

I've cleaned sensors before. It's not that difficult. Just one of the new regular maintenance procedures we have to do when working with DSLRs.

As long as you are not ham-fisted or Michael J. Fox then you can probably clean the sensor yourself. There are places that will do it for you though. See if you can find somewhere reasonably priced first.

Self-cleaning sensors help to stop dust from getting on the sensor, but they don't remove the problem entirely. You'll still need to have your camera serviced every one or two years depending on how often and where you swap lenses and how clean you keep your shit.

Those self cleaning sensors only shake some kinds of dust off. They can't stop everything. If you change lenses in the wrong environment or leave the body open for long enough then dust gets in.

In before more bad advice.

Don't use a blower. Any piece of dust inside a blower will become a projectile that can scratch/damage your sensor.

What I recommend is using a liquid cleaner and a swab. The swabs come sealed so when you are ready to clean you open one up, put a few drops of liquid on it and then clean the sensor.

The swab is the exact height of the sensor, so you gently go across one way, flip it over and go across the other way. Then you are done.

The liquid I have is made by Photographic Solutions but I'm sure there are a lot of good ones out there. The swab looks more or less like the one in this photo.

Worst advice so far. Wet cleaning is always done after dry. Often you don't even need wet cleaning.

Done it 3 times and each time had a PERFECTLY clean sensor after one go.
