3 What materials do I need for proper cleaning?
14 Cleaning Procedures
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 pol-
lute 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 produce
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
feedthrough adapters. Do not use them on optical head adapt-
ers, as the center of a pipe cleaner is hard metal and can dam-
age the bottom of the adapter.
Your pipe cleaner should be new when you use it. If it has col-
lected 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.
Dry stick cleaner
Compressed air
Compressed air can be purchased from any lab-
oratory supplier.
