wlaidlaw Posted January 12, 2018 Share #1 Posted January 12, 2018 Advertisement (gone after registration) 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?

jaapv Posted January 12, 2018 Share #2 Posted January 12, 2018 I would never attempt to remove dust that I suspected of being sharp with a lollipop cleaner. 1 Link to post Share on other sites More sharing options...
wlaidlaw Posted January 12, 2018 Author Share #3 Posted January 12, 2018 I would never attempt to remove dust that I suspected of being sharp with a lollipop cleaner. I thought all dust, other than pollen, mite corpses (the disgusting looking Demodex arthropods that live in everyone's skin pores) or shed skin cells, looked like jagged rocks under a powerful enough microscope.

SrMi Posted January 12, 2018 Share #4 Posted January 12, 2018 Always try to blow the dust away with a blower before resorting to chemical cleaning. So far, blower solved all my CL sensor dirt problems. 1 Link to post Share on other sites More sharing options...

wlaidlaw Posted January 12, 2018 Author Share #6 Posted January 12, 2018 I usually use a HEPA filtered Rocket Blower, then either the lollipop or an Arctic Butterfly. Sadly on using a sensor loupe, there seem to be two lumps of gloop, which will need a wet clean. Wilson Link to post Share on other sites More sharing options...

Wilson It does. Don't forget broken pieces of eyelash from peering at the sensor from above. But the nasty stuff is not soft dust but minuscule - or even not so minuscule- grains of sand which actually are miniature rocks. Link to post Share on other sites More sharing options...

Boojay Posted April 30, 2018 Share #10 Posted April 30, 2018 Yes, after rocket blower failing to remove everything - aps-c swab and eclipse, just did one sweep, thought I had everything but noticed later I did miss one dust spot. Will save that for later, I change lens often and think I'm a dust magnet! Link to post Share on other sites More sharing options...
pebbles Posted May 13, 2018 Share #11 Posted May 13, 2018 Surely blowing dust away merely moves it around inside. Is it not best to vacuum the sensor ? Link to post Share on other sites More sharing options...
wlaidlaw Posted May 13, 2018 Author Share #12 Posted May 13, 2018 I am always worried about how much vacuum to apply. At least the rocket blower is a zero damage device. I have modified my rocket blower with a HEPA filter, so at least I am not blowing dust in. I always hold my cameras with lens bayonet down and hope that the dust will make a gravity assisted exit, once blown around with my rocket. I also have one of the quite expensive Visible Dust Arctic Butterfly static brushes, which I have used for years before wet cleaning but I am still not convinced it is not a "Snake Oil" device and has no effect at all. I religiously clean it by switching the motor on with the brush immersed in Iso Propyl Alcohol to clean any grease off it but even so........ I have been cleaning sensors since beta testing the dire Contax ND in 2003, the world's first and pretty awful full frame digital. I still find a wet clean with a swab by far the most effective. I have a small tool box full of patent sensor cleaning devices, none of which really work. Wilson Link to post Share on other sites More sharing options...
