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. […]

New laptops come in squeaky-clean packages, with spotless keyboards, dustless LCD screens and smooth trackpad. After years of use, however, you would notice your keyboard getting shadows from all even small food particles wedged in between the rough finish. The LCD screen and trackpad might even be oily because of contact with your fingers. While […]

When I clean lenses I can tell when they get superlatively clean because all resistance in moving the Q-tip on the glass surface seems to disappear. Looking at the lens obliquely in a bright light also shows zero smudges, streaks, or spots on a very-clean lens. You can achieve this with IPA, but it might […]

For a photographer, there are few things as vexing as a dirty lens.  I was fortunate to have someone in a camera store recommend that I try ROR several years ago.  Why was I asking for a recommendation?  Because over and over, previous cleaning fluids just didn’t clean.  Imagine my delight when ROR left my […]
