3 Cleaning Information
Preferred Procedure
Use the following procedure on most occasions.
1 Clean the connector by rubbing a new, dry cotton-swab over the
surface using a small circular movement.
2 Blow away any remaining lint with compressed air.
Procedure for Stubborn Dirt
Use this procedure particularly when there is greasy dirt on the connector:
1 Moisten a new cotton-swab with isopropyl alcohol.
2 Clean the connector by rubbing the cotton-swab over the surface
using a small circular movement.
3 Take a new, dry soft-tissue and remove the alcohol, dissolved sediment
and dust, by rubbing gently over the surface using a small circular
movement.
4 Blow away any remaining lint with compressed air.
An Alternative Procedure
A better, more gentle, but more expensive cleaning procedure is to use an
ultrasonic bath with isopropyl alcohol.
1 Hold the tip of the connector in the bath for at least three minutes.
2 Take a new, dry soft-tissue and remove the alcohol, dissolved sediment
and dust, by rubbing gently over the surface using a small circular
movement.
3 Blow away any remaining lint with compressed air.
How to clean connector interfaces
Be careful when using pipe-cleaners, as the core and the bristles of the
pipe-cleaner are hard and can damage the interface.
Do not use pipe-cleaners on optical head adapters, as the hard core of
normal pipe cleaners can damage the bottom of an adapter.
