Step1：
Be flexible cleaning against light pollution (dust, fiber particles)
Use a blow balloon, blown off the contaminants which scattered on the surface of the optical element.

Step2:
Be flexible cleaning for slight contamination (stains, fingerprints)
Infiltration a unused swab or cotton balls with acetone or isopropyl alcohol] . Gently wipe the surface of the optical element with a wet cotton, do not force friction. Drag wet cotton on the surface, drag speed control. The stay behind of the wet cotton liquid can be evaporate immediately, so they will not leave marks.
Can only use plain paper body stick cotton swabs, and high-quality medical cotton. We recommend the use of reagent grade acetone or isopropyl alcohol.

Step3:
Be strong cleaning for heavily polluted (splatter) optics
Infiltration a unused swab or cotton balls with acetone or isopropyl alcohol] . Gently wipe the surface of the optical element with a wet cotton.Wipe dry the excess isopropyl alcohol with a clean cotton swab on the optical element.If you removed the thin film coating.the performance of the optical element will be completely destroyed. If the color of the optical element is changed, it means the thin film coating has been removed, you need to replace a new one if the lens coatings damaged.
