How to clean bare fiber 
adapters
Bare fiber adapters are difficult to clean. Protect from dust unless they are in use.
CAUTION Never use any kind of solvent when cleaning a bare fiber adapter as solvents can 
damage the foam inside some adapters.
They can deposit dissolved dirt in the groove, which can then dirty the surface of 
an inserted fiber.
Preferred Procedure Use the following procedure on most occasions.
1 Blow away any dust or dirt with compressed air.
Procedure for Stubborn Dirt Use this procedure particularly when there is greasy dirt on the adapter:
1 Clean the adapter by pushing and pulling a new, dry pipe-cleaner into the 
opening. Rotate the pipe-cleaner slowly as you do this.
CAUTION Be careful when using pipe-cleaners, as the core and the bristles of the pipe-
cleaner are hard and can damage the adapter.
2 Clean the adapter by rubbing a new, dry cotton-swab over the surface using a 
small circular movement.
3 Blow away any remaining lint with compressed air.
How to clean lenses
Some lenses have special coatings that are sensitive to solvents, grease, liquid and 
mechanical abrasion. Take extra care when cleaning lenses with these coatings.
