is the finest lens cleaner I have ever found. I used it when
servicing optics for over 10 years and still I am amazed how well it
performs. ROR simply removes a microscopic oil residue on the
surface of lenses that is ineradicable with ordinary cleaning procedures.
This residue, a by-product of environmental pollution, is substantial and
when removed from a camera lens, a remarkable increase in light entry is
obtained, plus a comparable increase in clarity and definition. The
residue will reassert itself in time, depending on the exposure of the lens
and the environmental pollution content. ROR can be used
repeatedly on multicoated lenses and filters without danger of damage. In
fact, using ROR offers protection to lenses by inhibiting dust
You cannot use a treated Lens Cloth with ROR nor can ROR be used on

How to use ROR
The best lens tissue is Kimberly
Clark's Kimwipes (I sell those also) but Kleenex (white, supermarket
variety) works quite well as ROR emulsifies the minor wood
fiber content. Use sparingly, a little ROR goes a long way.
* Camera lenses: Apply ROR to tissue, gently
apply to lens and remove with tissue.
* Eyeglasses: Apply
a minimal amount directly on both sides of the lens and remove with tissue.
ROR should be applied with a tissue, so as not to unnecessarily
involve the dormant residues present between the lens and the metal frame.
In order to experience the efficacy of
ROR, take a meter (exposure) reading with your camera on a
fixed light source. Note the shutter speed and aperture setting.
Remove the filter (If installed) and clean both sides with ROR and tissue.
Now carefully clean the exposed front and rear element.
Carefully clean the eyepiece on your
Reinstall the lens on your camera and
observe the improved clarity. When you make that same meter (exposure)
reading, most notice an exposure increase of at least 1/2 stop.
