I have got stains on the camera lens because of exposure to the powder of a powder fire estinguisher. Other products could not remove them, ROR did. The lens would have been a write off, now it is back to pristine conditions. Good stuff.

ROR is amazing. I use it on all of my camera gear and on all of my computer gear too. It is the only cleaner that will remove virtually all of the streaks and dirt on a glossy computer screen. I have about 15 bottles of other brands that just sit on the shelf now. [...]

I bought ROR to use for cleaning my camera lenses…worked better than I expected. Streak free an spotless-it works great with disposable task wipers. Excellent product.

I have used ROR for years. It’s great, especially for that last little bit that you just  can’t seem to get with other fluids.
Ever ‘cleaned’ a lens and still seen little swirl marks and no matter what you do, they remain? Just use ROR and those marks will disappear.

I’ve used many lens cleaning solutions over the years but nothing compares to this product.

Every material object exposed to the environment, including bino and scope lenses, are coated with a microscopic oil residue, the unfortunate by-product of environmental pollution. This lens clean-er is the first one designed to remove this oil residue. In a National Bureau of Standards test, ROR increased optical resolution 40% over cleaning with standard lens [...]

I threw my Kodak solution out after I bought the ROR. The Kodak stuff never worked anyway. I may be the only one on this forum that gets a build-up of oily residue on my filters, but when that happens, ROR pulls it off in a jiff, no smears. I rarely use it on my [...]

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 [...]

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 [...]

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. [...]
