There is a small amount of dust on my CL sensor and what looks like it might be a couple of dots of the notorious Wetzlar Goblin Snot, that afflicts new M cameras. Before I go away on a long trip next week, I thought I should at least start with a pristine sensor. I have plenty APS-C swabs left over from my M8 and Olympus EP-5. For solvent, I have a choice of Eclipse, lab grade 100% Absolute Ethyl Alcohol, IPA or Visible Dust Smear Away. I found Eclipse or Ethyl Alcohol best on M sensors but not good on the SL, which "preferred" Smear Away. I am going to guess that the CL sensor's coating will be more akin to the SL than the M and therefore, I propose to use Smear Away. I also have an Eye-Lead sticky lollipop but never had great success with that, as it seemed to leave lines on the sensor, which had then to be removed with a swab and solvent. It mIght however, be good for clearing scratchy dust before using a swab.
Anyone else cleaned a CL sensor yet and if so, what solvent/method did you use?
