By using higher-grade alcohol, circuit board users can thoroughly clean and maintain a circuit board of any size in a few simple steps. Higher-grade (around 95 to 99 percent) isopropyl alcohol and ethyl alcohol are the most effective cleaning solvents.

For dust: Microfiber cloth

How to clean a laptop — Jon Martindale/DigitalTrends

People who wear glasses or own a camera know about this little tool all too well. After all, it's the best way to clean a camera lens or eyeglasses.

Designed to remove dust and debris without producing lint or scratching delicate surfaces, microfiber cloths are the best place to start when cleaning a laptop screen. You can use other cloth-based materials or Clorox wipes alternatives, but they are more likely to leave behind debris.

Warning:Absolutely do not use a paper towel or tissue. They might seem soft when blowing your nose, but they are extremely rough on scratch-prone displays.

Step 1: Shut down your laptop. Not only is it safer, but having a blank screen can help you see dust.

Step 2: Pressing gently on the display, use a microfiber cloth to wipe in one direction. Don't scrub or wipe in circles, as this could damage the display or just move the dust particles around.

Step 3: Continue wiping across the display until it's dust-free.

What about using a duster? This is also a safe way to remove dust if the coating is extremely light. Avoid feather-style products, which simply push dust into a cloud. Instead, find one that collects dust, like the dusters made by Swiffer. If using a Swiffer duster, remember to turn off your laptop before using it.

There's no set method for removing dust, though you may want to move in an X pattern from top to bottom.

For dirt and grime: Damp sponge

Sometimes you'll end up with more than dust on your display. Instead of rubbing at it with your microfiber cloth to no avail — and potentially dirtying the cloth in the process — you can use a damp sponge instead. And you can always microwave a sponge to disinfect it first.

What you need:

A brand new household sponge.
Distilled, deionized, or filtered water.

Warning:Absolutely avoid standard tap water. Unseen minerals can scratch your display.

Step 1: Shut down your laptop and unplug it from its power source. If possible, remove the battery.

Note: If you're worried about potential drips falling onto your keyboard, place something light over the keys that won't absorb liquid.

Step 2: Wet the sponge with water and wring it out to eliminate drips.

Step 3: Use the sponge to gently wipe the screen's affected area. Watch for drips and clean them up immediately.

Step 4: Once the area is clean, wait for the display to completely dry before closing the lid or using your machine.

For oils and sticky stuff: Cleaning solutions

If the cloth and sponge methods failed to clean your laptop's screen, it's time for a safe screen-cleaning spray. However, you can't use justany substance. Specific chemicals scratch the surface even if you're using a microfiber cloth.

Avoid these substances at all cost:

Acetone
Ammonia
Ethyl acid
Ethyl alcohol
Methyl alcohol
Methyl chloride
Surface cleaners
Toluene
Window cleaners
Any other corrosive substance

You can still purchase third-party cleaners, but they absolutely must not include the chemicals listed above. Alternatively, you can create a cleaner using the following:

50% distilled water and 50% white vinegar.
50% distilled water and 50% isopropyl alcohol.
100% distilled water and a drop of dish detergent.

Step 1:Turn your laptop off and unplug it from its charger. If you're able, also remove the battery to prevent any electrical issues.

Note: If you're worried about potential drips falling onto your keyboard, place something light over the keys. A material that won't absorb liquid is your best bet.

Step 2:Pour or spray your chosen cleaning fluid onto a microfiber cloth. Be sure the fabric isn't wet, just damp.Never spray cleaning fluid directly onto your screen.Even though they evaporate quickly, applying liquid to your screen is a sure way to damage it.

Step 3: Gently rub the cloth over the affected area. Rub in small circles to avoid streaks. If you apply too much force, you could potentially cause permanent harm to the screen.

Step 4: Repeat this process until the screen is completely free of moisture. Make sure there is no pooling or drips on the keyboard or other hardware.

Step 5: You will have to wait for the screen to dry after cleaning it. Once it's dry, you can close it and turn it on.

We put our laptops through a lot on a day-to-day basis. We often eat and drink while scrolling, soiling our computer with the contents of our lunches. We owe it to our computer to keep it clean. Following all the steps outlined in this guide should help make your laptop look a little less homely.
