7.2 Cleaning the screens
Screens consist of single or double screen elements. Each screen element has a delicate optical screen surface
structure dedicated to its functionality. The optical surface can easily be damaged if the screen is handled incor-
rectly. Only handle screens while wearing gloves with a soft texture (e. g. cotton gloves).
Avoid touching the rear beaded surface unnecessarily. It is easily damaged.
The screen is a high-precision optical component. It is made of plastic and is not scratch-
proof. Only use a soft, damp cloth when cleaning.
If the screen is only slightly dusty or is showing particles, a vacuum cleaner with a soft bristle or a feather duster
is recommended. Clean compresses air can be used, but it makes the screen statically charged, attracting air-
borne particles. The brushing direction should always be along the optical structures in the screen if existing.
If the dirt on the screen is heavier, possibly from fingerprints, soft lint-free cloth or paper towel can be used. If
required the screen may be cleaned with lukewarm distilled water containing mild soap. Never apply cleaning
solution directly onto the screen surface. Instead, add cleaning agent to the cloth or towel, then wipe the sur-
face. It is important that the screen should be completely dry after treatment.
Never use cleaning agents with solvents as these may destroy the screen. Also, never rub hard
or persistently on the screen in order to remove stains, as this will cause deformations in the
surface which will appear as stains.
Don’t store screens at temperatures exceeding 40ºC (104ºF)
