    Evening all, I have been having a problem with some very stubbon dust spots on my sensor ( sounds as if I should go to the doctor!!) tried the normal camera sensor cleaning but the camera has not shaken off these little spots, can anyone recommend how I clean this, many thanks, Lee

    There are many ways, I have used Eclipse fluid and some sensor wipes, I bought them from Warehouse express. You will find lots about this in the forums.

    And now the confession I cleaned my old 300D about every 3 to 6 months. On my 40D as a year approached it was looking like needing a clean so I was going to and the shutter failed so the kind people at Canon cleaned it when they out the new shutter on.

    I do not recommend this as a cleaning way Wink

    Eclipse fluid is not the best thing to use.
    Look for purpose made cleaning kits or just clone out the marks in PS.

    You get a version of Eclipse fluid specially for sensor cleaning, (Eclipse E2 Lens and CCD Cleaning Fluid). From memory it is what Canon service people use, well it was when I had a 300D.

    Eclipse works superbly. The only thing that purpose made cleaning kits do that Eclipse doesn't, is relieve you of a lot more money.
    The end result is the same.
    IMO anyway.

    Eclipse works fine.

    However, there was an issue with E2 fluid being used on a few the original 5D's (a very small number apparently) where the sensor coating wasn't thick enough

    I used the Visible Dust swabs and fluid successfully (after the Arctic Butterfly sensor brush left a nasty smear on the sensor).

    It's also worth remembering that you can record dust delete data on the 40D and the DPP raw processing program that came with the camera will then automatically remove dust spots from the file. I tried it recently and it does work.
