I have several dust particles that just appeared on my sensor after being out in the field. I have tried a hand air blower to remove these annoying spots. Does anyone have any other suggestions to cleaning your sensor? I found the following article has anyone used this method? I am at a loss of what to do.
thanks in advance,
Greg

| When I take pictures in the dark, I always use noise reduction and have pixel mapping turned on. I also always clean my lenses before a shoot. If I don't turn on noise reduction, any image that is on the darker side of the spectrum, will have lots and lots of rogue pixels that are either white or dark red. I'm not sure if its dust or crappy senors. I think its mainly because my camera is junk, but noise reduction helps a lot. |

Greg,
The copperhill method is used by a number of folks here, including myself, and is one of the most effective methods for sensor cleaning. I recommend either purchasing the "spatula" tool from them or buying the Walmart spatulas and making your own, if you are so inclined.
Pec-pads are alos great for lens cleaning, I will not be without them.
The Eclipse fluid is a very good cleaning solution, it's essentially purified methanol. Less pure grades of methanol should not be used.

A garden hose works well but be careful of the pressure so as not to damage the sensor.

Thank You Fritz I ordered the kit five minutes ago. I was really starting to worry that my only real alternative was to ship my camera to Canon. I am glad to hear that people here are using this system, it eases lots of my fears. Again, thanks for the info.

| I use the copperhill kit as well, as do others I know on this site. It's a good tool, and when used properly works wonders. |

Ok I got my copperhill sensor cleaning kit and swabbed my sensor about ten times even going so far as using the "brooming" technique. I still have a dust spot on my sensor does anyone have any suggestions at this point.

not sure if this will link to an image with the spot but here goes

Very occasionally folks have reported that the y have spots thata won't go away even after using a swabbing technique like copperhill. There are two possibilities...
1.) The spot is inorganic and is actually a defect in the AA filter itself
2.) The spot is on the surface but is insoluble in Eclipse (methanol).
The first issue is of course a send-it-in-have-it-fixed scenario.
I run into the second issue occasionally with lenses; often things get on the lens that are not soluble in methanol. Many things that are completely insoluble in methanol are soluble in water, however. If you have a source for VERY pure water (see note), and are confident in using just enough to dampen but not fully wet the swab, you could try a cleaning with that, and follow with Eclipse on a fresh swab. The post-cleaning with Eclipse is necessary to eliminate residual water from the surface.
I've done this wwith lenses, but never have needed to do it on a sensor (yet).
If you're not completely confident trying this, don't. Call Canon and ask for their recommendation. Likely they will tell you to send it in :-(
Note:
The water needs to be highly filtered, deionized water. This is not usually sold, but is made on-site in many companies that run analytical laboratories. Deionized water always needs to be stored in a plastic or glass container, never metal. It needs to be fresh, and what is not used is discarded.

I found a brush that is designed for cleaning sensors. Works great.
