Lens cleaning

① For loose lint or dust: use an air bulb to blow off any loose particles.
② For smudges or fingerprints: squeeze a few drops of acetone onto the lens tissue, wetting the diameter of the optic.
③ For droplets or oils: use a cotton swab and distilled vinegar to wipe the lens, then use a wet cotton swab to remove any acetic acid. Clean with a dry cotton swab.
