I make a living telling folks how to get the most out of their TV, so you can imagine my embarrassment the other day when I noticed that my own TV screen was covered in a fine layer of dust. As someone who studies TVs for a living, how could I miss this?
In the days since, I’ve let myself off the hook. In fact, we should all let ourselves off the hook for our dusty, fingerprint-laden TV screens. It’s easy to ignore a dirty screen — we’re not really paying attention to them when they’re off, and when they’re on, grime, gunk and spots are tougher to notice.
But here’s the deal: A dirty screen can make even the brightest and best TVs look not-so-hot, especially under certain lighting conditions. Don’t let the dust win.
How does a dirty TV screen affect the picture?
Contrast and clarity are two terms that are frequently thrown around when discussing TV performance, and it makes sense, as they’re key aspects of an immersive picture.
Details in the brightest and darkest regions of the picture are at risk of being obscured.
When dust and fingerprints accumulate, they can have an adverse effect on both contrast and clarity. Details in the brightest and darkest regions of the picture are at risk of being obscured, and it can be especially noticeable during daytime viewing.
Whether you own a budget-friendly TV or high-end OLED or Mini-LED TV, dust is going to be a problem. Affordable, entry-level TV screens tend to be more affected by blemishes due to the limitations of their display hardware, and if you spent a pretty penny on a premium model, you’ll surely want it looking its best.
Thankfully, cleaning a TV isn't as big of a time suck as you might think it'd be.
How to safely clean a TV screen
We’ve put together an extensive guide to cleaning a TV screen, but if you’re looking for the basics, here’s what you need to know:
- Avoid using paper towels or random rags you might have lying around, as their materials can damage the screen. Instead, only use a microfiber cloth.
- Never use a window-cleaning solution to clean your screen. In fact, don’t use any chemicals at all. It’s OK to use a touch of water to dampen a microfiber cloth before cleaning, but never apply water directly to the screen itself.
- Avoid putting pressure on the screen while you wipe it down.
How often should I clean my TV screen?
I recommend cleaning your TV screen every one to two weeks in order to keep your picture looking its best.
If you notice a fingerprint or smudge, it’s in your best interest to clean it as soon as possible. The longer a blemish hangs around, the harder it may be to clean later.
Additionally, if your TV is situated near a frequently opened window or sliding door, you may want to clean it more often. (My TV is set next to a living room window, and over the last several weeks, the screen has accumulated a fine layer of pollen that drifted in through the open window.)
Developing a screen-cleaning routine will ensure that your TV looks its best for years to come.
