Hello,

Iīm just about to start with LF and now my first lens was shipped (Schneider Geronar 210mm, was a display model). It looked perfect beside a finger print on the glas inside.
So I tried to clean it: first only with a microfiber cloth and a Anti-static Tiger Cloth (Kinetronic) but there were wiper traces. I also tried to use a small amount of lens cleaning solution but it didnīt help.

Iīm a bit afraid I could have damaged the lens.
What is the best way to clean a lens?

I would appreciate if you could help me with your experience.

Regards, Mareike
