Cleaning Using a Swab
Specially treated swabs (stick cleaners) are available for cleaning inside
connector adapters or hard-to-reach ferrule tips. These swabs, often
referred to as “lint free” or “alcohol free” swabs, are available from many
vendors. See Figure 99. Stick cleaners are available in both 2.5 mm and
1.25 mm sizes for use on SC and MU connectors respectively.
Note
NEVER use a household cotton swab and/or alcohol to clean a fiber
optic connector. A cotton swab or alcohol may leave a residue on
the ferrule tip.

Do not use compressed air or aerosol air to clean a fiber optic
connector.
To clean a recessed ferrule using a swab, perform the following
procedure:
1. Insert the swab into the adapter as shown in Figure 100 and rub the
ferrule tip with the swab.
