CARING FOR AND CLEANING THE SCREEN
With reasonable care, you may expect many years of dependable use of your Stewart projection
screen.
GENERAL MAINTENANCE
The surface of your screen is delicate, so we encourage you to keep your screen clean. Special
attention to these instructions should be followed when cleaning.
‣
Avoid getting any foreign objects on the screen as cleaning may prove very difficult. It may not be
possible to remove scratches, paint, ink, etc.
‣
A draftsman-style brush may be used to lightly
whisk away any loose dirt or dust particles.
This type of brush is usually available at office
supply stores. Stewart Filmscreen has an
optional screen cleaning kit that contains the
proper type of brush. Contact your dealer if you
would like to obtain this cleaning kit (see Figure
17).
‣
For tougher spots, you can make a cleaning solution using a water-based detergent and warm
water. To make the solution, mix one part Simple Green, 409, or other water-based industrial
cleaner with three parts warm water. Moisten a clean cotton cloth or cotton swab with this
solution, moisten the stained area, and gently lift off the stain. Never use an aggressive
scrubbing action as you could damage the screen surface by removing the optical coating.
Remoisten the area with clean water and dab dry with a clean sponge or cotton cloth. Any
residual watermarks will evaporate on their own within minutes.
‣
Contact the factory if you have questions about removing difficult spots.
⚠
CAUTION
Oils and grease from hands can easily transfer to screen material.
Be careful not to touch or scratch the viewing surface.
⚠
CAUTION
Do not use cleaners containing alcohol as they can damage the optical surface of the
screen fabric.
