To keep your projector image clear and sharp, you will need to keep the screen clean. No matter what type of screen you have, you can use simple household items like cleaners. By removing dust and marks, and then wiping the entire screen, you will have a clean surface to project!
Part 1 of 3: Clean Dust and Small Marks
Step 1. Spray the screen with short blasts of compressed air to loosen dust
Buy a can of compressed air that is commonly used to clean electronic components. Hold the nozzle about 1 inch (2.5 cm) from the screen and take a few short shots of air. Blow over the entire screen to loosen the dust.
You can buy a can of compressed air at an electronics supply store
Step 2. Wrap some 2-inch-thick masking tape around your hand
Wrap the tape around your fingers with the sticky side out. Cover your nails and knuckles to prevent them from coming into contact with the screen.
Using wider tape will help you cover a larger area when cleaning the screen
Step 3. Gently press down on the screen to remove the 3/4 inch (20 mm) dust marks
With the tape around your hand, apply pressure to the dust mark on the screen. Take your hand off the screen and continue to pat gently until the mark disappears. Switch between the palm and the back of your hand to prevent residues from re-depositing on the screen.
- Wear latex gloves to avoid fingerprints or scratches on the screen.
- If the mark is very large or does not come off with the tape, you may need to use a more thorough cleaning method.
Part 2 of 3: Clean the entire screen
Step 1. Mix a solution of 95% warm distilled water and 5% dish soap
Stir the ingredients in a bowl until completely mixed. This will help remove tough or sticky stains from your screen.
Multipurpose cleaners are good substitutes that you can buy in stores
Step 2. Dampen a microfiber cloth with the solution
Dip a clean white cloth in the water and wring it out completely, leaving it damp to the touch. A cotton cloth is recommended as it is softer and lint-free.
Avoid using hard or abrasive sponges, as they can damage the screen
Step 3. Rub the screen from side to side by pressing gently
Work from top to bottom. Wipes across the screen, horizontally and in one direction. Make 5 inches (13 cm) long strokes and slightly overlap the next one with the previous one to make sure you cover the entire screen.
Cleaning the screen in a circular motion can scratch or damage it
Step 4. Immediately wipe excess moisture from the screen using a dry cloth
Take a new cloth and dry the screen. Make sure to continue sweeping back and forth to remove any moisture that may have remained on the screen.
Do not allow the remains of the compressed air spray to be absorbed or remain on the screen, as they can leave permanent stains
Part 3 of 3: Remove any residual marks
Step 1. Dip the head of a cotton swab in rubbing alcohol
Make sure the head of the swab is completely wet with the rubbing alcohol. The alcohol will be more powerful than the solution you used previously and should only be used for spot cleaning.
Isopropyl alcohol can be purchased at pharmacies or related stores
Step 2. Clean the mark with the wet head of the swab
Just clean the area that contains the mark. Make short taps, making sure to overlap over areas that you have already cleaned. Spin the swab as the mark slides off the screen.
Use the cotton swab gently. You should not press the swab too hard on the screen
Step 3. Use the other side of the swab to remove the stain
Do not let the alcohol get the screen wet, as it can cause a permanent stain. Rub the dry end of the swab over the mark to remove the alcohol and any other marks that remain.
