Instructions for Use

The most common source of damage to glass surfaces and sensitive optical coatings is abrasion, which is caused by rubbing of fine particles that are resting on the surface. We stress that you do not dry clean your lens because of high risk for scratching and abrading of the coating. We do however, recommend the following:

  • Use a can of compressed air or a camel hair blower brush to remove any particles that may be resting on the surface.
  • Place a few drops or spray a little bit of ROR on the surface.
  • Let the solution settle for a few moments, and then gently wipe with a lens cleaning cloth or tissue, making sure that you use as much of the clean area of the cloth or tissue each time you wipe.
  • If you are working on a small surface, squeeze a few drops or spray some ROR onto the applicator that you are using and commence the cleaning as described above.
  • Apply enough pressure to effectively clean the optical surface.
  • Use a clean cloth or tissue to do a final wipe of the surface, again using sufficient pressure for each additional motion.
  • Use a professional task wiper to apply and remove ROR. These soft, chemical-free, non-abrasive tissues offer great absorbency and streak-free cleaning on sensitive surfaces. If you have to use a generic variety of tissues, make sure it is untreated.
  • Untreated microfiber cloths also work well as long as you wash them frequently and keep them dust-free in a pouch or container.
  • Be sure to check the make-up of your micro fiber cloth before using it with ROR. Treated micro fiber cloths can integrate poorly with ROR, leaving a residue on the surface.
  • We recommend you wash and dry the cloth before proceeding with your application.

Some Helpful Hints

Should any streaking or residue remain after cleaning and drying, it is most likely due to either a tentative application or a lengthy interval that has passed since the last cleaning. Should that prove to be the case, a second application and drying might be required to restore the surface to the desired result. We highly recommend a regular maintenance schedule to ensure that surfaces are kept residue free, thereby prolonging the life of your valuable equipment.
