Proper cleaning of a 400D camera sensor

I have not done it myself, but I saw neat little lense cleaning "pens" for around $10 at Harvey Normans the other day.

I'd try washing it off with some IPA then a gentle air nozzle to dry it off. Not sure if the IPA will damage any coatings or coating adhesives involved....

I would be very surprised if there wasn't a utube video showing how to do that. worth having a search I reckon

Have done this several times to my S3 over its lifetime. There are right ways and wrong ways to do it. A very fine lint-free cloth over a rubber spatula and a few drops of ipa on the blade end works the best for me. A couple of wipes and any dust and residue are gone. Be sure to shoot a blank frame (I find that a clear blue sky is the best) and check it for dust specks and residue marks after cleaning.

You can buy a kit of Eclipse Sensor swabs its a one off clean with each swab.
