(i) Scientific-grade acetone (ii) Air bulb (iii) Lens tissue (iv) Plastic lens holder (v) Cotton swabs (vi) Eye dropper (vii) Rubber gloves
Using rubber gloves, place lens in lens holder. Use air bulb to remove all loose contaminants from the optic. If the contaminants are still visible please proceed to step #2.
Place a new piece of lens tissue over the optic, completely covering the optic
Fill eye dropper ½ full with acetone.
Drip acetone on the center of the optic until it is saturated to the outside diameter.
Pull the lens tissue slowly across the optic. Going too fast will leave acetone residue behind. Acetone will evaporate when the tissue is dragged across the lens at the correct speed.
If top side of lens is contaminated, repeat steps 1–5.
Place clean optic in the machine quickly to avoid getting airborne particles on the clean optic. If spots, pits, or scratches are still noticeable, the optic may need to be replaced.
