Manual Sensor Cleaning for Canon 40D

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

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.

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.
