  1. Use an air bulb to blow off any loose contaminants. (dust, lint particles)
  2. Squeeze a few drops of acetone onto the lens tissue, wetting the complete optic’s diameter. (smudges, fingerprints)
  3. Using the cotton swab and distilled vinegar, wipe the lens. Immediately use a wet cotton swab to remove any acetic acid, then clean with a clean dry cotton swab. (spittle, oils)
