Hello! I have a 12' wide Da-Lite Tensioned Advantage Electrol Screen with DualVision material used for rear projection in my terrace/outdoor home theater. This screen is about 12 years old and it has never been cleaned. As you can imagine, it is no longer pristine since it has been exposed to the humidity of the outdoor terrace. I live in the Caribbean so there is no damage from cold weather whatsoever.

I'd like to receive your advise on how best to clean this screen to make it as even as possible and to remove the humidity spots I see.

In addition to the cleaning, I also see some wrinkling waviness towards the bottom of the screen. Should I assume this cannot be fixed?

I have attached a couple images to illustrate my questions.

I am grateful there are no off-color (dark) stains on the screen. I have a powerful 5200 color/white lumens projector that overpowers most of the stains at a throw distance of 9'. Thank you in advance for sharing your knowledge with me!

Typically you may use mild soap and water. This is described on their website, and you may call them.

But, a screen that's been outside for over a decade very likely may have some serious staining issues that can't be corrected.

Wrinkling in a non-tab-tensioned screen is normal. It's amazing it hasn't been pretty bad for many years.

Thank you. I'll try that this weekend.

Da-Lite provided me with detailed instructions and a link to YouTube on how to clean the screen. I'll try this tonight!

Here are the instructions:

CARE OF PROJECTION SCREEN SURFACES
Da-Lite has developed cleaning methods that we know from experience will not damage your screen.
The steps as outlined below follow a progression of cleaning methods from general maintenance and
care to deep stains. If you follow these steps in order, you can expect to maintain the optical properties
of your Da-Lite screen throughout its life cycle.
GENERAL MAINTENANCE AND CARE:
? Keep your screen rolled up in its protective case or housing when not in use.
? Clean your screen frequently with a feather duster or cleaning cloth to avoid accumulation of dirt
or dust.
? DO NOT place the screen surface in direct sunlight or areas of excessive moisture or heat.
? DO NOT place the screen surface in the path of direct airflow or in a “dirty” environment.
? DO NOT scrub the screen or use abrasive or petroleum based cleaners.
GENERAL CLEANING:
? Use a soft, clean, lint free cloth or sponge when applying cleaning methods.
? Use a blotting action when applying cleaning methods rather than a wiping action to avoid
damage to the surface.
? Use gentle compressed air to remove particles or specks.
? Use gentle pressure with masking tape to remove small marks of around ¾” or 2cm in size.
? Use distilled water with a mild detergent to clean larger areas of the surface.
? DO NOT proceed to further cleaning methods if you are using a High Power®, High Contrast High
Power®, Silver Lite 2.5 or Silver Matte surface from Da-Lite.
PERSISTENT MARKS OR SPOTS:
? Remove marks or spots in small areas with a melamine foam cleaning pad or rubber eraser using
light pressure only to avoid damage to the surface.
? Remove marks or spots in large areas with an all-purpose spray cleaner. Da-Lite’s recommended
cleaners are Clorox® Green Works and Formula 409®.
DEEP STAINS:
? Remove deep stains with ethyl, isopropyl or denatured alcohol. If streaking occurs, revert to the
cleaning methods for Persistent Marks or Spots.
If marks, spots or stains still occur after applying these cleaning methods, please contact your sales
representative or Da-Lite Customer Service with the following information:
1. The type and size of stain.
2. The surface type or name.
3. The total surface size.
4. The approximate date of purchase.
