Clean and Sanitize Your Screens Regularly
The best way to remove grease and dust from a computer or phone screen is to use a microfiber cloth and some clean water. Before you start, make sure the tablet or cellphone is switched off and unplugged from the mains. Water and electricity are not a safe mix.
How to Clean and Sanitize Your Smartphone or Tablet
Start by turning the power off, and unplug your device if it is wired. Then using a dry microfiber cloth, remove any surface dust by gently wiping the display screen. I use an iSound antibacterial, anti-static cloth. It cleans as well as sanitizes your touchscreen. An anti-static cloth helps to reduce future dust deposits on the screen.
To remove stubborn marks and greasy smears you may need to dampen the cloth with a little water. Don’t spray the liquid directly onto the screen. Instead, spray a little water onto the cloth and then use the dampened cloth to wipe the screen. Don’t be tempted to use abrasives or scourer pads on the touchscreen as it can be easily damaged. When the smears have gone, leave the screen uncovered and the power off for at least an hour. This allows it to dry completely, and be safe to reconnect to a power source.
How to Clean Your Phone Screen (and Some Products to Avoid)
What Cleaning Materials Shouldn't Be Used?
Touchscreens are simple and intuitive to use, but they are also easy to damage if cleaned incorrectly. Avoid using anything that could scratch or over-wet the device.
- Reusing old rags to clean your screens may sound environmentally friendly, but you risk having to replace the touchscreen if the material used is even mildly abrasive. Stay safe and use only new, soft microfiber cloths or pads.
- Water and sanitizing solutions should be used sparingly. They cause short-circuits and warping of the device. If you need to use a liquid to get rid of tougher smears, always spray onto a cloth first, rather than direct onto your cellphone or laptop.
- Don’t use alcohol or ammonia-based cleaners.
- Don’t press the screen too hard when cleaning or you will wear out the pressure sensors.
Germs, Bacteria, and Diseases on Your Phone
Bacteria, Greasy Smears, and Fingerprints
Touchscreens are found everywhere; smartphones, computers, cars, and restaurant ordering screens. Have you ever thought about how often the screens are cleaned and sanitized? The swab results from a recent survey of touchscreens at may disgust you. Researchers from London University took bacterial swabs from self-order touchscreens at eight McDonald's restaurants in England. Every single touchscreen they sampled had fecal matter on it. McDonalds said the screens were cleaned frequently with a sanitizer solution. But you only need one person to use the screen whose personal hygiene is not as good as your own, for the screen to contaminate your hands.
How often do you wash your hands after using one of these screens, and before eating your takeaway meal with your fingers? Fecal matter contains bacteria that cause food poisoning, vomiting, and diarrhea. Touchscreens are popular, but people leave their mark (literally) on the screen. A buildup of smears and germs can be bad for your health. You should clean and disinfect touchscreens regularly to keep them hygienic and free from bacteria and viruses. This is especially important now that coronavirus is spreading.
How to Avoid Germs When Using Public Touchscreens
Unless you’re a hermit, you'll encounter public touchscreens every day. You can’t clean these yourself, yet you can’t avoid using them. So, how can you keep you and your family safe from the bacteria that are on them?
- Rub the screen with a disinfectant wipe before use. These are cheap to buy and discreet to carry.
- Try to touch the screens as little as possible. Use your thumb or “pinkie” finger to select your onscreen choice.
- After using the public touchscreen either go to the bathroom and wash your hands with soap, or sanitize them with a disposable wipe.
- If you are eating afterwards, haven’t washed your hands, then eat using a napkin instead of your fingers to hold the meal.
- Talk to your children about why you are doing these things. Help them protect themselves by getting them in the habit of always washing their hands after they’ve been to the toilet.
- If you have fever, cough, or difficulty breathing, seek medical care early. This will minimise the chance of you spreading the germs; you could have a serious viral infection.
