Hi,

I'm wondering if it is safe to use pure 2-propanol (isopropyl alcohol) for lens surfaces. I have used it for my old Switars and an old Fujinon eng zoom, it worked without issues. But I'll maybe shoot a part of a small-budget feature soon (or work as an ac) and must to know if this stuff can harm the multicoating or filter surfaces ( my friends assume that can happen :ph34r: )

(the lens isn't mine, and it is more expensive too, so raping the coatings would be a shame, although I know the lens is already scratched by others :rolleyes: )
#It will be about five years old 2/3" Fujinon tv zoom and Formatt filters, I don't remember details.

thank you for answering :lol:

It won't hurt the glass, but there are better cleaners. Try to find some ultra clarity or panchro lens solution. Panchro, in particular, won't leave a residue that needs to be buffed out like straight alcohol does.

Kimwipes give you the best bang for your buck. I like to keep a pad of rosco tissue on my belt, mainly for ease of portability.

Pancro is expensive if you're paying for it out of pocket, but it's the best out there.
