The best cleaner I’ve ever used is ROR

The best cleaner I’ve ever used is ROR (Residual Oil Remover, www.ror.net). It simply cleans better and with less effort than any other solvent, yet is non-toxic. A report on ROR’s site about cleaning camera lenses was hard to swallow until I saw the effect of cleaning a brand-new eyepiece and saw the difference in light transmission. Though it wasn’t a TeleVue, the eyepiece came from the factory with dirty lenses that showed an ever-so-slight yellow tint when looking through at a fluorescent light. After cleaning, the eyepiece had a noticeably brighter image without the yellow tint. I presume the eyepiece lenses simply weren’t clean when the eyepiece was assembled. I didn’t take it apart, but I’d bet the inside surfaces weren’t clean either.

ROR Stands the Test of Time

I’m careful with my lenses, but still, they need cleaning periodically. I’ve been using ROR for about six years on all my optics ranging from collector camera lenses to everyday camera lenses, and the eyepieces and objective for my telescope. It’s never damaged a coating. I blow dust off and then brush the lenses with a soft brush, then lightly wipe them with a clean microfiber cleaning cloth that’s been sprayed with ROR, and then finish up with Q tips. They come out looking like new.

No lens cleaner can even come close to the cleaning quality of ROR

Several years ago I had the opportunity to try a lens cleaner that made a claim of adding up to two f/stops of light transmission. (The product was called ROR, short for Residual Oil Remover.) That got my attention and I took up the challenge by checking a Mamiya RB 180/4.5 lens with a filter. The lens and filter appeared to be fairly clean. I made an electronic test, then cleaned the lens and filter. I made the test again and was astonished at the results: A full stop and a half gain!

I immediately put it to use as the lens cleaner of choice on my bench. When I first started using it on customers’ lenses and filters, after receiving their repaired lenses they would call to say that I had forgotten to “return the filter” or “didn’t put the front lens element back in.” I explained that everything was indeed intact and that they should look closer — the lenses and filters were so clean that the customers couldn’t see them!

Since then, sales reps have asked me to try their brands of lens cleaners. I put the cleaners through an objective side-by-side test with ROR. The results have always been that no lens cleaner can even come close to the cleaning quality of ROR.

I also use ROR to clean a wide variety of other things, including removal of ink, blood and coffee stains. So far, I have found only one thing that should not be cleaned with ROR and that is film. The emulsion will be destroyed. Like any other cleaning solution, when cleaning an unfamiliar surface, try ROR on an area that is disposable in case there is a problem. To me, ROR is the undisputed King of the Hill of lens cleaners.
