Dust specks on the projector. Grainy pictures on the TV. Choppy sound coming from the speaker. Pesky wires all over your home media room. Don’t let these factors interfere with your viewing or listening pleasure. Cleaning and maintaining your home theater equipment should be simple and trouble free if you know the basics of it.
Some brands require specific maintenance for each model, so make sure to always refer to the user manual that came with your home theater system.
Screens and Projectors
- Turn off the lamp and unplug the power cord from the wall outlet before cleaning and allow the projector to cool for at least 30 minutes.
- Use a standard-lens cleaning brush or piece of lens tissue dampened with lens cleaning fluid.
- Use only recommended nonabrasive lens-cleaning materials.
- Use a soft, lint-free cloth to clean the projector and the ventilation grilles. When grilles become dirty, wipe them with a soft cloth dampened with diluted mild detergent, and then wipe them with a dry cloth.
- Use a soft cloth moistened with a mild detergent to clean the projector housing.
- When you clean or replace the lamp of the projector, be sure to hold the handle of the lamp, not the bulb.
- If dust has accumulated around the pins of the power plug, unplug the power cord and clean it using a dry cloth. Clean the power plug at least once a year.
- If your projector is regularly exposed to dust, clean it every three months.
- For a projector screen like the Da-Lite Da-Snap Screen, unroll the screen on a clean surface.
- Use a white, clean cloth (100% cotton preferred) that is dampened with water. Gently wipe the area in one direction. Wipe dry with a fresh cloth after each cleaning session. To clean a stain, use denatured alcohol (methanol or methyl alcohol) following the procedure as for water.
- Touch lens with your fingers.
- Apply pressure to the lens, because you can easily scratch it.
- Spray insecticide on or inside the projector.
- Use benzene, thinner, or other flammable solvents and aerosols to clean it.
- Let rubber or plastic materials contact with projector.
- Use projector near water or in contact with water.
- Use newspaper when you unroll a projector screen for cleaning.
- Use circular motions when cleaning a projector screen.
DVD Players and Receivers
- Make sure your player or receiver is unplugged whenever you need to use liquid to clean it.
- Use a disc cleaner to clean the lens inside of a DVD player
- Use dry or lint-free cloth on the front and side panels.
- Dust the vent holes.
- Use a Q-tip dipped in water or isopropyl alcohol.
- Slightly dampen the cloth with water to remove fingerprints or any other residue.
- Use paper towels.
- Use harsh cleaning materials.
Surround Sound Speaker Systems
- Clean the cabinets using a soft, lint-free cloth. You can slightly dampen it with water.
- After carefully removing the grilles from the speakers by pulling them forward, gently clean them with a quick pass from a vacuum cleaner with a brush attachment.
- Clean the driver in the speaker with a soft bristle paintbrush.
- For small speaker parts, use a micro-fiber cloth to remove the dust.
- For an outside speaker like the Earthquake Granite 5.25” Outdoor Speaker, use a cloth moistened in mild detergent and water.
- Outdoor speakers are made to endure water contact, but with freezing temperatures, cover speakers with tarp or plastic bag.
- Remove leaves, dirt, spider webs, twigs, rocks, and other things that may build up in and around the outdoor speakers.
- Use any other cleaning agents or chemicals.
- Use salt water or vinegar.
- Get any water on the driver cones or tweeter domes.
HDMI Cables and Connectors
- Bundle audio cables, video cables, and power cables separately, using zip ties or other cable organizers to neatly arrange them.
- Label cords and cables.
- Use cord catchers (or make your own with big binder clips) to hold the cables behind the desk when you unplug them.
- Unplug and replug the cables connected to your home theater systems every few months to keep the connection smooth.
- Twist or staple HDMI cables, that will cause malfunction.
