Employing Windex for a spotless computer screen.

  • September 7, 2023

What exactly is Windex?

Windex, an illustrious American brand of glass cleaner, is manufactured by SC Johnson and is esteemed for its unparalleled capacity to clean various surfaces without leaving any streaks behind. Glass and mirror surfaces, in particular, are rendered impeccably clean with this product. Windex is the go-to product for both residential and commercial environments when one needs to banish dust, grease, fingerprints, and many other kinds of grime from glass surfaces, window panes, and even some types of impervious materials.

One of the standout features of Windex is that it typically comes in a handy spray bottle design. This makes the task of evenly applying the solution on surfaces to be cleaned utterly convenient. As for the ingredients, Windex usually consists of water, cleaning agents, sudsing agents, and occasionally, ammonia, which is renowned for tackling the most stubborn stains and dirt.

When it comes to using cleaning products such as Windex, it’s paramount to abide by the instructions printed on the product packaging to guarantee a safe and effective cleaning experience. Similarly, it’s crucial to store all cleaning items safely out of the reach of children and avoid any direct contact with one’s eyes or ingestion of the product. Should accidental ingestion or eye exposure occur, one must seek medical help right away.

Be mindful that product compositions and availability could encounter changes over time. Thus, it’s always a smart move to stay updated with the latest information, either by checking the product’s label or reverting to the manufacturer’s official website.

So, what’s the magical stuff that lights up our beloved desktop and laptop screens?

More often than not, the wonder material is a fascinating thing known as Liquid Crystal Display, or LCD to its friends. A favorite among tech gurus and gadget lovers, it owes its popularity to a host of cool attributes, including razor-thin elevation, barely-there energy consumption, and the ability to render images almost worthy of an artist’s canvas.

Let’s dive a bit into the technicolor universe of the LCD screen, which is composed of multiple sequential strata.

  1. Hovering at the rear end, we have the Backlight, our trusty illuminator, strewing sunshine all across the screen.
  2. Next in line are the Polarizing filters. Their mission? To bring order to the light zipping across the screen and elevate the image quality into the realm of marvelous.
  3. At the heart of the LCD lies the Liquid Crystal layer. This intriguing assembly of molecules enjoys playing peek-a-boo with the light, either letting it scamper across or clamping down on it, thereby conjuring up the dazzling pictures you see on-screen.
  4. Color filters work their magic next, assigning specific hues to the light straggling through the liquid crystal layer.
  5. Ensuring stability and security are two burly Glass substrates cuddling the delicate LCD panel, fully prepared to spring into action should any harm threaten their charge.
  6. And of course, how can we forget the indispensable Thin-Film Transistors (TFTs)? Nestled cozily on one glass substrate, they juggle myriad electrical currents destined for each pixel, which in turn checks the rampant spree of gas molecules.

Something electric happens when a current streaks into the TFTs. Suddenly, they’re inspired to deck up selective pixels in the liquid crystal layer, either by clearing the path for light or by routing it, eventually painting the multihued carnival that you see on the screen.

While LCD continues to be the reigning queen, display technology is in an endless state of evolution. Newer premium desktop and laptop monitors are brandishing swanky screen types such as Organic Light Emitting Diodes (OLED) or MicroLED that bring to the table a spectacular contrast, richer colours and ultra-snappy response times, putting the traditional LCDs experience to the pale. Yet, on this side of September 2021, LCD is still basking in its limelight as the most sought-after screen type in the computer realm.

Ever wondered what makes our computer screens a magnet for dirt?

Numerous reasons can contribute to our computer screens taking on a dingy appearance:

  1. Persistent dust and floating particles: Our surroundings are constantly filled with dust and other floating particles, which, over time, can rest on the screen turning it dull and murky by forming a thin sheet of grime.
  2. Stubborn fingerprints and skin oils: Adding a personal touch to our screens, quite literally, leaves behind fingerprints and oily smears. This unwanted layer not only spoils the screen’s appearance but also marks its unpleasantly dirty presence.
  3. Unfortunate food and beverage spills: A casual sip or snack near the computer might lead to an undesirable splash, which can stain and mar the sparkling surface of the screen.
  4. Smoke and harmful environmental pollutants: Locations with smokers or polluted air could make your screen a hostage to external smoke and toxins. This infiltration will give your screen a filthy and foggy appearance.
  5. Pet fur and dander: If your cuddly companions linger around your workspace, their hair and dander might choose your screen as their resting place. Common places for pet shedding can have your computer screen looking untidy.
  6. Incorrect cleaning equipment: Using rough cleaning materials can scar the screen’s protective covering apart from scratching the surface. This makes the screen more vulnerable to clinging dirt and filth.
  7. Static electricity’s pull: Screen surfaces can develop a static charge, a magnet for dust and detritus. Its constant buildup turns your screen into a miniature dust magnet.

Regular upkeep and thorough cleaning can ensure your screens remain spotlessly clean. Usage of correct cleaning tools like microfiber cloths and specified screen cleaners is crucial to prevent screen damage. Plus, maintaining a clean environment can also lower the amount of dust finding its way onto your screen.

What should be the frequency of giving your computer screen a good cleaning?

When should you spruce up your computer’s display screen? Well, that depends on a variety of factors, such as the conditions where your computer is kept, and of course, your personal inclinations. However, it’s generally wise to cleanse your screen often to sustain its sharpness and hinder the accumulation of pesky dirt.

For the majority of us, a weekly or biweekly refresh of the computer screen will keep it looking sharp. That said, if you are in a dust-prone or smoke-filled workspace, you might need to up the frequency. Similarly, having little ones or pets around can also mean you’ll need to deal with more smears and spills.

Keep in mind, it’s paramount to use the right cleaning equipment and strategies to prevent damage. Here are some handy tips for a safe sprucing of your computer’s face:

  1. Switch off your computer or display before embarking on your cleaning venture, to ward off any electrical surprises.
  2. With a soft, non-lint microfiber cloth, gently clean the screen. Steer clear of abrasive materials like paper towels that could graze the screen’s surface.
  3. For those stubborn stains or smudges, a lightly soaked cloth or a dedicated electronic screen cleanser should do the trick. Be cautious not to oversoak your cloth; you wouldn’t want to drench your screen!
  4. Never splash any liquid directly onto the screen. Dab it onto your cleaning tool instead.
  5. Wipe the screen using gentle, circular swipes. Vigorous pressure could risk harming the Liquid Crystal Display or other screen technologies.
  6. If you’re using a touchscreen device, adhere to the maker’s guidance for cleaning. Some touchscreens might need unique cleaning procedures.

With regular cleaning rituals and the utilization of suitable cleaning methods, you’ll lengthen the lifespan of your monitor and ensure a crystal clear, smudge-free experience.

Ever wondered if Windex could be your computer screen’s secret cleaning weapon?

Generally, it won’t be a good idea to clean a computer screen with Windex or other household cleaners containing ammonia. Though Windex may be superb for sprucing up your glass windows, it falls short when it comes to treating electronic displays, particularly those boasting LCD, LED, or OLED technologies.

Ammonia-laced Windex has a high potential to wreak havoc on your screen’s protective layers such as the anti-glare coating. Moreover, the chemical compounds found in such cleaners may undergo adverse reactions with the components of the screen, causing unwanted side-effects like discolouration and streaks, even escalating to terminal damage.

Play it safe when it comes to your computer screen. Opt for a specialized screen cleaner or a mild, display-friendly concoction. You can whip up your homemade elixir by adding equal parts of distilled water and isopropyl alcohol (70% concentration, or more). Apply your cleaner of choice onto a soft, microfiber cloth devoid of lint, adopting a gentle, circular cleaning motion.

It’s vital to keep liquids away from your screen. Excess moisture may trickle into the sides, raising the risk of damaging the internal parts. Steer clear from abrasive materials such as tissues or paper towels; they could leave fine scratches on your screen.

The maintenance of your computer screen becomes far easier when you adhere to the manufacturer’s specific cleaning directives. Armed with the right cleaning arsenal, you can ensure your screen remains in top-notch condition, extending its lifespan by a considerable margin.


The computer screen is our gateway to the digital world, so maintaining its pristine vision is key to a delightful and efficient interaction. Over time, the screen can be a gathering spot for grime, dust, fingerprints, and smudges, all of which muddle the display and interfere with its function.

A crisp and clear screen not only boosts the visual appeal of our virtual workspace but also enhances our whole digital interaction. The deposition of dirt and particles on the screen can trigger annoying glares and reflections, putting a strain on our eyes and resulting in discomfort during extended periods of use. Besides that, a smeared or unresponsive touchscreen can obstruct accurate touch input, disrupting effectiveness and performance.

To maintain your computer screen in top notch condition, it’s crucial to employ both secure and efficient cleaning methods. The use of household cleaners like Windex, which contain ammonia, is a big no-no, as they can ruin the screen’s shield coatings and components. Go for specially designed screen cleaners for electronic displays or concoct a mild cleaning mix using equal amounts of distilled water and isopropyl alcohol (with a concentration of 70% or more).

Before commencing the cleaning process, it’s imperative to turn off the computer or monitor to circumvent electrical risks. Utilize a soft, lint-free microfiber fabric to keep from scratching the screen. Do not apply the cleaning solution directly on the screen, instead moisten the cloth with it, ensuring that the cloth is merely slightly damp to prevent unwanted moisture from dripping in the corners.

With soft, circular motions, meticulously remove dust, fingerprints, and smudges from your screen, focusing on stubborn stains. But remember, applying too much pressure could damage the screen, so proceed with caution. Steer clear of items like paper towels or tissues, as they could leave visible scratch marks and lint on your screen.

Keeping your computer screen spotless is crucial for enhancing visibility, boosting work efficiency, and easing eye stress. By comprehending what leads to dirt and grime accumulation and embracing safe methods to cleanse, you can ensure your computer screen remains in an immaculate state.
