Mine is not coming unscrewed on the first part. Any suggestions? I can easily follow your great video instruction after I get that first on off! I can't seem to budge it? I also have a Nikon 70mm to 300mm to clean as well...same issue, it won't unscrew?
your video 👍👍👍👍👍👍👍 Please make a video of the full element cleaning .... back lens element and middle element also of the same lens Nikon 200-500.

Try heating your screw
@@icammech Its the first ring that unscrews, do you mean I should heat that? I can untwist it, not a screw issue.
@@romy4593use white petroleum, it will remove rust or gum, then it will unscrew
@@icammech Thank you! Will try that with another lens before the big zoom lens...since I have two with this issue.
