Ensure that you use natural cotton swabs. Foam swabs will
often leave behind filmy deposits after cleaning.
Use care when cleaning, and avoid pressing too hard onto your
optical device with the swab. Too much pressure may scratch
the surface, and could cause your device to become misaligned.
It is advisable to rub gently over the surface using only a small
circular movement.
Swabs should be used straight out of the packet, and never used
twice. This is because dust and dirt in the atmosphere, or from a
first cleaning, may collect on your swab and scratch the surface
of your optical device.
Soft tissues These are available from most stores and
distributors of medical and hygiene products such as
supermarkets or chemists' shops.
We recommend that you do not use normal cotton tissues, but
multi-layered soft tissues made from non-recycled cellulose.
Cellulose tissues are very absorbent and softer. Consequently,
they will not scratch the surface of your device over time.
Use care when cleaning, and avoid pressing on your optical
device with the tissue. Pressing too hard may lead to scratches
on the surface or misalignment of your device. Just rub gently
over the surface using a small circular movement.
Use only clean, fresh soft tissues and never apply them twice.
Any dust and dirt from the air which collects on your tissue, or
which has gathered after initial cleaning, may scratch and
pollute your optical device.
Pipe cleaner Pipe cleaners can be purchased from tobacconists,
and come in various shapes and sizes.The most suitable one to
select for cleaning purposes has soft bristles, which will not
produces scratches.
The best way to use a pipe cleaner is to push it in and out of the
device opening (for example, when cleaning an interface). While
you are cleaning, you should slowly rotate the pipe cleaner.
Only use pipe cleaners on connector interfaces or on feed
through adapters. Do not use them on optical head adapters, as
the center of a pipe cleaner is hard metal and can damage the
bottom of the adapter.
