Originally posted by dsmithhfx OK, but how do you remove "nose grease" smeared all over the lens by an unhygienic camera technician?
Sounds like a failed first attempt by some amateur...
Excess can be removed with any lens safe solvent.
In 1986 at Olympus we used Freon TF, which is no doubt banned now.
Any mild degreaser containing alcohol or ammonia should remove it easily.
A Pentax camera repair specialist some of you know tells me Windex works well and is even effective against mild fungus.
When cleaning/polishing lens elements use several layers of soft lens tissue,
and always add a little moisture by fogging surface with your breath.
If at first you don't succeed...
