Re: Oily goo removal ...

I am kindof freaky about self-cleaning the sensor. ANother reason a decent back up is really necessary...

On all of my Canon DSLRs it appears as if the first few times I
cleaned them there was a lot of smearing. Perhaps this was, as has
been suggested, oil from the mirror mechanism. Vaporized and
deposited ... a possibility.
I used 100% isopropyl (the brand name cleaning stuff, Eclipse, is
methanol) and cleaned a few times.
After the smears were gone, a quick dry swipe with a sterile swab
(the things you seem them use on CSI!) and the blower bulb have
worked 100% of the time since.
BTW, I typically shoot at f/16 in the studio, against white
backdrops ... I get to see dust as soon as it arrives!

I don't believe in fate, but I do believe in f/8!
