Big projector screens are mostly everywhere serving different purposes. People use it for watching blockbuster, play games, watch sports events or even use them in conference rooms.
It is always thrilling seeing pictures or motion pictures on the big screen but things look messy when blackspot starts appearing on the screen and distorting images. Blackspots are defects on the screen caused by dust, insects, and other contaminants.
When the screen is having too many notable blackspots, you probably start thinking of replacing it.
Some manufacturer’s guide always instructs against cleaning the projector screen as it may damage the screen, that is not totally true if you are meticulous with this cleaning guide.
In this article, you will learn a step by step guide on how to clean a projector screen.
Types of screen materials
Based on price, availability, or quality, different people use different materials for their projector screen hence, the cleaning process for various materials differs.
Before we dive into the process let’s look at the various types of material used in making the projector screen.
The common materials are:
- Special light rejecting materials
Let’s jump into the various materials and their cleaning process.
There is a special wall paint used in making a projector screen and also easy to clean.
To clean the screen surface, you need the following items:
- Soft clean rags
- Distilled water
- Dish detergent
- Gently wipe the dust from the screen surface continuously from top to bottom by using the soft clean rags.
- After every four to five strokes, change the rag to avoid dust accumulation and a tweak to the screen.
- Make a solution containing 10% detergent and 90% distilled water.
- Dip a dry, soft clean rag in the solution, wring until it is damp to touch, and do a wet mopping like the dry mopping process.
- Ensure you repeat the dipping and wringing process after three strokes from top to bottom.
- After three strokes of wet mopping from top to bottom, use a new rag to dry watermarks.
- After completing this process, wait for two to three hours and test using light from any source including the projector to check for blackspot.
The projector screen made of paint is cheap. So, if the cleaning process above doesn’t remove the stain, you might consider repainting your screen surface.
The cleaning process involves laundering the fabrics, pressing it, and keeping it safe when not in use.
If the fabrics get damaged or the laundering process cannot remove a particular stain, you should consider purchasing another fabric.
Impact-sensitive projector screen materials
Did you just go back up to the list to check if this was one of the materials?
Maybe you did but don’t worry, I am trying to make a cluster of material that requires very little impact when cleaning or else, you damage them.
The materials I categorize in this group are Vinyl, Spandex, Canvas, and special light rejecting materials.
Vinyl is the most common material used in the home theater screen while Canvas is transparent and majorly used in making an acoustically transparent screen.
To clean this projector screen successfully you should get these items or improvise if they are not available:
- Extension pole
- Dust mop
- Screen mop
- Screen cleaning detergent
Any basic liquid dish soap with no special additives or bleach can be used. Too much chemical will leave a streak after it dries and can cause the screen to dirty faster.
OxiClean High Def Sparkling Fresh Liquid Laundry Detergent (60 oz) will do a great job.
- One 60 oz bottle of OxiClean High Def Sparkling Fresh Liquid Laundry Detergent
- Created for every day, it’s tough on stains, but not on your fabrics and has an invigorating...
- Powers away tough dirt, dissolves persistent odors and breaks down set-in stains
- Stroke in a single direction from up to down, as half stroke, can leave a mark on the screen. Successive strokes can overlap.
- After every two or three strokes, check your dust mop for excess dust and wipe it off and start over from where you let off.
- Do a wet mopping process after dry-mopping from left to right.
- You might come across an area that requires more concentration (like candy, coke stains, etc.), STOP. Work the area back and forth with the screen mob until you find out that it is clean. Once it is done, go back up to have your one continuous stroke.
- After every four to five strokes, STOP. Remove your screen mop and clean in the solution (a mixture of small soap and water) to clean it up a little bit using your hand to wring out the mop head.
- Keep an eye on the condition of the water in your bucket and when you notice the water is getting dirty, change the solution.
- To prevent leaving a watermark on the screen, squeegee-off water from the side you have mopped. Ensure drying the squeegee with a paper towel after every stroke.
- Ensure you cover the entire surface.
- Upon completion of cleaning the screen surface, repeat the process above for the back of the screen for retractable screens.
AVOID GOING IN CIRCULAR MOTION WHEN MOPPING. It can permanently damage the screen.
The last resort for an unsatisfied result from the cleaning process should be the use of Isopropyl alcohol which is available in drug stores. Ensure you wear gloves and safety goggles when handling chemicals.
You can check out Swan 70% Rubbing Alcohol on Amazon.
Use the Q-Tip soaked in the alcohol to gently clean the part where the stain persists and ensure you wipe it immediately.
