Cleaner fluid for Russian lenses

[Jones]

Hello everyone!

What cleaner fluid would you recommend for soviet lenses. I have a collapsible I-22 with greasy lens that needs to be cleaned but I'm afraid of damaging the coatings. I've heard that alcohol based cleaners may damage coatings of old lenses so should I just avoid them or are there any other concerns. Should I get some special cleaner or do the common cleaners work OK. I have acetone laying around but is that bit too excessive.

I thank you for your advice in advance.

Rubbing alcohol or lighter fluid.

Rubbing alcoohol has water in it, doesn't it?

If you use a little on a tissue and don't spill half a gallon to soak into the lens, it's fine.

Eddy Smolov advised me to avoid alcohol and to use lighter fluid instead.

I use lens tissue dampened with vodka (even for German and Japanese lenses) when simply breathing on the lens is not enough. It's rarely needed.
