15 Cleaning Instructions

If possible avoid using denatured alcohol containing additives. Instead,
apply alcohol used for medical purposes.
Never try to drink this alcohol, as it may seriously damage to your health.
Do not use any other solvents, as some may damage plastic materials and
claddings. Acetone, for example, will dissolve the epoxy used with fiber
optic connectors. To avoid damage, only use isopropyl alcohol.
Cotton swabs
We recommend that you use swabs such as Q-tips or other cotton swabs
normally available from local distributors of medical and hygiene products
(for example, a supermarket or a chemist's shop). You may be able to
obtain various sizes of swab. If this is the case, select the smallest size for
your smallest devices.
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.
