What chemical solution to use for cleaning digital camera sensors?

Click For Summary
SUMMARY

The discussion focuses on the challenges of finding effective cleaning solutions for digital camera sensors, particularly in Canada. Users express concerns about the purity of available isopropyl alcohol and alternatives like 94% alcohol from SAQ stores in Quebec. The consensus is that while 94% alcohol may primarily consist of ethanol and water, there is skepticism regarding potential impurities that could leave residue on CCD sensors. The user also shares a negative experience with using vodka, which resulted in streaks and necessitated professional cleaning.

PREREQUISITES
  • Understanding of CCD sensor cleaning techniques
  • Knowledge of alcohol purity and its effects on optical surfaces
  • Familiarity with chemical composition of cleaning agents
  • Experience with photography equipment maintenance
NEXT STEPS
  • Research the properties of 94% ethanol and its suitability for sensor cleaning
  • Explore alternative cleaning solutions specifically designed for CCD sensors
  • Learn about the effects of impurities in cleaning agents on optical equipment
  • Investigate professional cleaning services and their methods for sensor maintenance
USEFUL FOR

Photographers, camera technicians, and anyone responsible for maintaining digital camera equipment, particularly those seeking effective and safe cleaning methods for CCD sensors.

Since it is impossible to get certain cleaning solutions (in Canada, at least) like "Eclipse" (methanol) and pure isopropyl alcohol (from drug stores) is adulterated with some kind of greasy oils that leave smear marks behind, I would appreciate some help as to what chemical solutions might be available to do the job? What is required is merely that there be no residue left when cleaning the CCD.
For instance, I have found 94% pure alcohol (from the government owned SAQ alcohol controlled stores in Quebec). My question is: just what might the remaining 6% contain? and How can I find out what that might be?
My "long ago an far away" studies in chemistry suggest that that would be H2O; but I am skeptical of the reliability of the SAQ.
Thanks for any help.

If it is for human consumption (and I guess it is), it is quite pure mix of water and ethanol.
 
Thanks Borek,
Since it comes from the Alcohol Authority, one would assume that, of course. But knowing these greedy b...tards we cannot assume that they have not added some othe garbage.
But if it is only water, then I would think it would be ok. And considering that if nothing has been added after the distilling process ( I know that after 94% it turns into some other stuff that's not too cool), then we could assume that the water would evaporate with the alcohol.
As for human consumption, godforbid one should drink this stuff straight... I have had that 151 proof rum straight (I don't recall the brand, but it's a good one)... but then I was a bit out of my mind, though it was good. At the time, anyway.
I did try cleaning the ccd with Vodka (Moskovskaya) and it worked partially; the 60% water was not pure water... probably leftover potato-peel juice. It left streaks and I had to have it cleaned by "professionals" at break-the-bank rates. Oh, well... Thanks much.
