I had a friend that does camera repairs recommend a cleaner called R.O.R. Has anyone here used it? Supposedly he started using it after a some repair companies suggested it and that it's supposed to be the best on the market.

Might be similar to Opticlean which is a clear liquid that is painted onto the glass and allowed to cure. The liquid then forms a skin that you peel off thus removing contaminants.

Be very careful with those things. Some coating layers (e.g. that of the Jupiter-37) are very thin and very easily damaged even by simple cloth actions, let alone by peeling films.

It's not like Opticlean. It's a liquid and gets the residual oils and contaminants off that other solutions wont.
I talked with a Canon rep today and he said their techs use it and recommend using it once every 6 months- no more, no less. They also claim that you should gain 1/4 to 1/2 stop on metering because it's so good.
I think I am going to give it a shot on cheap glass first.

Yeah, I want to see the results for myself. The reason they state that is contaminants and residual oils are deposited on the glass and the removal increases the light that is able to enter the lens.
I did a little digging on the net and found many people giving the same claim. Once I have tested this myself, I will post the results. I will give metering examples under same lighting conditions etc.... and see what happens.

But then again some people say to use Vodka and get great results too Laughing

I've been using the R.O.R. for a while now. It works quite well for removing the residual oils from a lens - however, it does leave a slight film of its own after cleaning, which I remove using an alcohol based lens cleaner. It seems that the R.O.R. is a detergent based, which would account for the film.

I don't know about the claim of a 1/4 to 1/2 stop difference after cleaning. The cameras I've used it on were mostly thrift shop purchases, often with decades worth of accumulated gunk and grime on them, and the R.O.R. did an excellent job in cleaning them. On these cameras, the difference wasn't a mere 1/4 to 1/2 stop - it was probably closer to 4 or 5 stops... Laughing

I don't use R.O.R. as my regular cleaner because of the film it leaves, but I do use it occasionally (maybe once a year or so) for cleaning, as it seems to do an excellent job.

Orio, I agree. The lens should be REALLY dirty to get 1/2 or 1/4 gain after cleaning. Shocked

I, personally, use zippo lighter fuel. I am satisfied with the results.

Go to www.promaster.com then to accessories from the left side menu and choose cleaning supplies. I use theirs Optic Cleaner and didn't recognize yet any damage to the lens coating Cool

. However there is an information (small print) to avoid use it on contact lenses. In Chicago area -Helix Camera (Chicago, Highland Park) 2 fl oz costs $3.99 retail
