Just prior to Valle, I managed to screw up my courage and do a wet cleaning on both cameras using the Copper Hill "Eclipse" solution and foam pads wrapped on a swab that's made for APS-H - sized sensors. They make "handles" for APS-C, APS-H or Full Frame.
- Blast of Rocket Blower
- Visual inspection with a magnifier I have from the SensorKleen Pen set (wasn't gong to swab them if they really didn't need it)
- A few drops of Eclipse, one pass (gets the upper 5/8 of the sensor)
- Flip the swab around and do a second pass to get the remaining portion
- Let it dry for a beat or two
- Re-inspect with loupe
- Good to go!
Only had one or two spots that, if there wasn't so much clear sky, would never have shown up.http://www.copperhillimages.com/index.php?pr=Copper_Hill_Products
