I saw this on talknex: If you are thinking about wet cleaning your sensor with Eclipse - BE WARNED. DONT DO IT! User had an issue with Eclipse cleaning solution on their NEX6. Since OMD and EPM2/EPL5 (and GH3!) use Sony sensors, I thought I'd cross-post. I have Eclipse for my Canon. Now, I have to admit I have NEVER had to wet-clean my Oly sensor, so maybe it's moot. The story ends well, as the user was able to get the sensor clean again.
