Action
1. Fold a microfibre cloth smooth and gently wipe remaining dust
particles from the lens. Wipe evenly with the smooth portion of
the cloth that has no folds or creases. DO NOT apply pressure
with your fingers - use the tension in the folded cloth itself to
collect dust.
2. If significant dust is still bound to the surface, dampen a clean
microfibre cloth with coated optics cleaning solution (damp,
not dripping). Wipe gently until clean.
1. Brush away most of the dust with a camel-hair brush and/or
blow away using a dust-free blower.
2. Roll a lens tissue around a swab and soak it in coated optics
cleaning solution. Tissue should be damp, but not dripping.

motion until the blemish is removed.
