Three Methods:Cleaning the MonitorMaking a Cleaning SolutionPurchasing a Cleaning SolutionCommunity Q&A

Cleaning your monitor regularly will help you see the display easier. There are many solutions available for purchase, but you can easily make a cleaning solution at home as well. Follow this guide to properly clean your computer monitor.

Method 1
Cleaning the Monitor

  1. 1
    Power down the monitor. This not only lowers the risk of electrocution, but will allow you to more easily see dust and grime on the screen.
  2. 2
    Wipe the dust off with a dry cloth. Go in slow, circular motions. Do not apply too much pressure to the screen. Make sure to use a lint-free, non-abrasive cloth to wipe. A large cloth is best, since it will help to reduce the risk of leaving streaks across the screen from finger pressure.
    • Suggested non-abrasive cloths:
      • Microfiber
      • Cotton T-shirt
      • Cotton handkerchief
      • Cotton tea towel
    • Avoid the following, as they are too abrasive:
      • Paper towels
      • Dish towels
      • Facial tissue
  3. 3
    Apply cleaning solution to the cloth. Do not spray the solution directly onto the monitor. Drips can lead to malfunctions and permanent damage. Instead, spray the cloth with the cleaning solution. Apply a small amount of cleaning solution at a time, as excess moisture on the screen can damage it in the long run.

  4. 4
    Clean the grime off with the cloth. Work in small circles, and avoid direct pressure on the monitor. Do not scrape at any smudges; allow the cleaner to dissolve them.
    • You may have to repeat the application and cleaning process several times for tough spots.
    • Wipe off any excess moisture when you are finished cleaning.
  5. 5
    Let the monitor dry. Make sure that the monitor is completely dry before powering it back on. This will minimize the risk of moisture damaging the internal components.
    • Do not use blow driers or any other heating mechanism to speed up the drying process. Let the drying occur by air.

Method 2
Making a Cleaning Solution

  1. 1
    Get the right water. Avoid using tap water when making a cleaning solution. Tap water often has minerals that can damage the monitor. Instead, use distilled water. Distilled water can be bought at most grocery outlets, or you can make your own.
  2. 2
    Add a cleaning agent. The two most popular cleaning agents for homemade solutions are isopropyl alcohol and white vinegar. Choice comes down to personal preference, as both are effective at removing tough grime. Avoid mixing the two though, stick with one or the other.
    • Do not use any cleaning agent that uses ammonia, such as window cleaners, as this can discolor your monitor.
    • When using isopropyl alcohol, don’t use more than a 50/50 mix with distilled water. If you’re using vinegar, start with a 50/50 mix and add more vinegar if the solution isn’t strong enough.
    • Vodka can work as a replacement for isopropyl alcohol.

Method 3
Purchasing a Cleaning Solution

  1. 1
    Read reviews. Most cleaning solutions use proprietary mixtures that they claim work best. See what other users have to say about the product before committing to a purchase.
    • Some solutions act as more of a polish than a cleaner, so make sure to read the full product descriptions.
  2. 2
    Get a full cleaning kit. If you don’t have any good cloth lying around, purchase a cleaning kit. These typically come with microfiber cloths suited to cleaning LCD displays.
  3. 3
    Consider cleaning wipes. If you’d like to avoid using and cleaning a cloth, you can purchase disposable cleaning wipes specifically designed for monitors.

    Power down and unplug the computer screen. Coil up the power cable so it will not get in the way of movement. Gently pick up the computer screen on the underside and back, avoiding the glass face. Move to the location of your choosing.
