Cleaning Instructions What do I need for proper cleaning?

Isopropyl alcohol
This solvent is usually available from any local pharmaceutical supplier or 
chemist's shop.
If you use isopropyl alcohol to clean your optical device, do not 
immediately dry the surface with compressed air (except when you are 
cleaning very sensitive optical devices). This is because the dust and the 
dirt is solved and will leave behind filmy deposits after the alcohol is 
evaporated. You should therefore first remove the alcohol and the dust 
with a soft tissue, and then use compressed air to blow away any 
remaining filaments.
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.
