I've read where some folks used a vinegar and water solution (sounds like a douche commercial) to spray on and wipe off to remove the water deposits.

Anyone know if this would adversely affect the opt-coat?

If not, what is the ratio of water to vinegar?

Thanks.
I wouldn't imagine vinegar would hurt it. When I've had to use vinegar for hard water spots it goes full strength onto the towel I am applying it with. Best of luck, that is very irritating.
