[QUOTE="tulku, post: 924343, member: 5203"] Losthwy , I think you have a good Process . I have been using a similar ( but shorter Process ) for decades . In my Work , I used to clean Lenses that cost more than most peoples houses . Mostly I used Ethanol in liquid and vapor form ( for bare glass & quartz ) , but these Lenses were never very dirty . I also was involved in Testing Contaminates and did find a really clean Optical Cloth , but its absorbancy leaves something to be desired .....such is life . . I bought a lifetime supply , but unfortunately that Cloth is no longer available . For my own use , I use Isopropyl Alcohol which is commonly available in 70% and 91% . I should state my personal Optics are never very dirty either . I use A Qtip soaked in the Isopropyl . I guess it would be prudent to spray the Isopropyl on first .....if the Optics had particles on them . If I buy used Scopes which are dirty ( fingerprints , etc . ) , on them ......I sort of just flood the Lens with Isopropyl for a while and then very gently swab it with the soaked Qtip , and do not use the same soaked Qtip for more than one pass . I always wear Nitrile Gloves as I don't want to Transfer any hand oils to the Qtip or Optical Cloth which would then re-contaminate the Lens . I then gently wipe with the Optical Cloth and change to a clean spot on the Cloth about every pass . Last step is to Breathe on the Lens and finally wipe again with the Optical Cloth .
