Modern TV and monitor screens have delicate anti-reflective and anti-glare coatings that are easily damaged by the wrong cleaning products. Many common household cleaners — including window cleaners like Windex — permanently strip these coatings. Use only the methods below.
Dust Removal (Weekly)
- Turn off the screen — a black screen shows dust far more clearly and helps you see what you've missed
- Use a dry microfibre cloth and wipe gently in one direction — circular motions can create micro-scratches in the coating
- Use light pressure — pressing hard on LCD panels can cause permanent pressure marks
Fingerprints and Smudges
- Turn off the screen
- Dampen a clean microfibre cloth with distilled water — not tap water, which contains minerals that leave spots
- Wring the cloth so it is barely damp — never spray liquid directly onto a screen
- Wipe gently in straight lines, working from top to bottom
- Follow with a dry microfibre cloth to absorb any remaining moisture
Stubborn Smudges
If distilled water isn't sufficient:
- Mix a 50/50 solution of distilled water and white vinegar
- Apply to the microfibre cloth — not directly to the screen
- Wipe gently and follow with a dry cloth
Some manufacturers provide a specific screen cleaning solution — check your TV or monitor's documentation if you're unsure.
What Never to Use on Screens
- Window cleaners (Windex, etc.) — ammonia strips anti-reflective coatings
- Paper towels or tissues — micro-abrasive and scratch screens
- Alcohol above 70% — can strip coating on some panels
- Household spray cleaners of any kind
- Excessive pressure — permanent pressure damage on LCD panels
