Before cleaning, make sure that the tip of the optical connector

substances.
Using a cleaner with a defective tip might damage the ferrule tip.
Always use a dedicated optical connector cleaner. If you use another
type of cleaner, the ferrule tip might become dirty.
Do not apply excessive pressure when cleaning. Doing so might
damage the ferrule tip.
Rotate the optical connector cleaner clockwise only. Rotating the
cleaner alternately clockwise and counterclockwise might damage the
ferrule tip.
