Cleaning your computer screen becomes necessary when the layer of fingerprints, food residue, and grime obstructs your view. TIROT/BSIP/Universal Images Group/Getty ImagesAn untimely sneeze, fingerprints, a dab of spaghetti sauce, your pandemic pet's damp nose, or cheese puff powder — these are some of the things that can dirty your screen.
Computer screens are often plagued by unwanted smudges, marks, and spots. Not only are these distracting, but they also make it harder to see what's on the display. In some instances, especially with touchscreens, these smudges may even become a hotbed for bacteria.
If you're looking for the most effective way to clean your computer screen, here's a great starting point: grab a clean, lint-free microfiber cloth. These cloths, similar to those used for cleaning glasses, will eliminate dust that has accumulated over time, and they won't scratch your screen. Start by turning off your computer (the dark screen helps you spot dust and dirt more easily), then gently swipe the screen horizontally in one direction followed by vertical swipes — always moving in a single direction. Circular motion can just shift the dust around. By working in a grid pattern, you ensure you capture more dust and make it easier to spot any missed areas.
What should you do if you remove the dust but still notice stubborn spots or grime? Avoid household cleaners like window or countertop sprays because ammonia or alcohol-based cleaners can damage delicate screens — unless you’re cleaning a glass screen like those on most Macs, and even then, be cautious with alcohol-based cleaners and steer clear of using anything that might scratch, like paper towels.
The best option is to create a DIY solution, mixing a 1:1 ratio of distilled water (never use tap water, as it can leave mineral deposits) and white vinegar. This cleaning mixture works well on screens without a glass coating, such as LCD and touchscreens. And if you're unsure about the screen type, it’s always safer to use this solution. Just spray it onto the microfiber cloth, not directly on the screen.
When unsure, it's a good idea to consult the screen's manufacturer — they may have specific recommendations for cleaning.
If you're in need of cleaning your computer screen but don't have distilled water or white vinegar, and don't want to go to the store, disinfecting wipes can work in a pinch — but only if you're certain the screen is covered by a glass layer.
