Interesting video. Something to keep in mind - you want to remove any debris from the lens prior to wiping/scrubbing with any implement. Leupold offer a lens pen (as to most all camera stores); you want to utilize the brush attachment to ensure anything that might scratch the lens has been removed.

Years ago the US Optics web site had a really great collection of information regarding optics including formulas etc, and one particular article on how to clean lenses.
Basically you simply clean the lenses with a Q-tip soaked with acetone.
Don't get too close to the outer edges if there are plastic rings used. Good scope wont have plastic.
Change the Q-Tip frequently.
This is how I've cleaned my lenses ever since. Works great.
The only way this will fail you is if you have plastic lenses, so don't do it to safety glasses or anything that does not have glass lenses.
And BTW... a thumbs up for the nice guys at Korth. They did a solid for me a while back and I appreciate it.

Any policy is a success by sufficiently low standards, and a failure by sufficiently high standards.
