Cleaning Information
What materials do I need for proper 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.
Your pipe cleaner should be new when you use it. If it has collected any dust or dirt, this can
scratch or contaminate your device.
The tip and center of the pipe cleaner are made of metal. Avoid accidentally pressing these
metal parts against the inside of the device, as this can cause scratches.
Compressed air
Compressed air can be purchased from any laboratory supplier.
