Cleaning Solutions
There are a variety of cleaning solutions you can use such as Reagent-Grade Isopropyl
Alcohol, Reagent-Grade Acetone and De-Ionized Water to ensure a long product lifetime.
A good solvent mix to use is a mix of 60% acetone* and 40% methanol. (Acetone alone
dries too quickly to dissolve all of the debris. The methanol slows the evaporation time, and
also dissolves debris that acetone alone would not clean.)
*Acetone should never be used on plastic optics or components as it will damage them.
Cleaning Procedure
Step #1
First use compressed air (aerosol can) to remove surface dust without directly contacting
any coating the optic may have. Wiping a dusty optic with cotton swabs or lens paper is
like cleaning it with sandpaper.
Step #2
Soak with solvent a Cotton-Tipped Swabs or Lens Tissue then use a circular motion
starting from the edge of the optic moving towards the center to wipe away any dust or dirt.
Repeat as necessary, each time use a new cotton swab or lens tissue.
