Zosxavius,

Is this the same as what you have? Check the second picture on the first post and post #12.

Ditto on the artists brush, the fine synthetic hair ones, usually golden in color. I've used them dry or ever so slightly damp, water or methanol, depending what it takes. If need be, between swabbing you can clean them with methanol, shake the excess, then clean and dry the brush with compressed air spray - just use the clean kind, not the generic stuff for blowing dust off things.

On my first attempt at cleaning my K10 sensor I bought a cheap camera sensor/lens cleaning kit. Following instructions I put a drop of cleaner on a swab, brushed my sensor, and waited for the cleaner to evaporate. Then I picked up the bulb with the brush on the end, swiped the sensor to loosen any stubborn dust particles, and squeezed the bulb to blow them away. That filled my camera, and covered my sensor, with a cloud of talc from inside the bulb.

It took me several attempts, over several days, to clean that mess out and remove all traces of talc from the sensor.

Ok you people have given me hope. Right now I have it down to one stubborn dust spot. The one I never could get off. Its not really affecting my shots. In the small handful it may crop up in a quick application of the clone tool in lightroom will fix it. As soon as I get around to it I will order some eclipse and sensor swabs. They don't seem to harm the sensor at all. Also methanol doesn't react from what I can tell. I applied too much and it really sat on there for some very tense minutes until I blew it all off. The sensor scope manufacturer told me I was using too much juice. That may be true. I think I will stick with the eclipse though. I change lenses a lot and dust will eventually be a serious problem again. I'm going to try to reduce foreign dust by being more careful about lens changes, but its reall inevitable. Especially since one of my favorite lenses is a mf push zoom.

I like the bulbs. I think I want to get one. I've used deflected compressed air, but there is always a chance that it is contaminated not to mention the potential for freezing the glass. I think that stuff just invites trouble. What looked like water spots don't seem to in any way affect image quality. So I am going to leave well enough alone until I have enough dust to warrant another wet cleaning. If it ain't broke....the perfectionist in me comes out too much sometimes.

Sorry for all the replies. I guess what I wanted to say was that this whole procedure terrified me, but then I realized that mere humans. Were capable of doing it, so why not me? I really just didn't want to do something foolish and all this talk from several people of oxide coatings and I got pretty nervous. Especially after reading some 5d owners actually had problems. Anyways thanks to the people that had experience and let me know I wasn't going to wreck my aa filter. Nobody locally wanted to help me except my friend and he shoots with mighty dirty nikons from what I saw of his d3's mirror box. The mirror was coated in dust. He shoots wide open portaits mostly, so it doesn't really bother him. I said "well I shoot landscape and buildings. You can see a lot at f11 and onwards....." it blows me away how people shoot so differently.

To kypainter: OUCH

I'm not feeling so bad after reading that.
