If you are looking for how to efficiently disinfect computer keyboard, then this tutorial just fits you needs as it will share how to disinfect keyboard keys of desktop and laptop step by step.

Why We Need to Sanitize the Computer Keyboard?

The computer keyboards will accumulate a lot of dust over time. The sweat and skin oil on our hands will aggravate the accumulation of dust and debris on the keys, meanwhile, many bacteria and viruses will adhere to the keys. Sometimes these Bacteria and viruses may be the source of inexplicable gastrointestinal discomfort or diarrhea. Especially in some public places with a large number of people, such as Internet cafes, libraries, hospitals, schools, etc., the computers used are dirtiest. As a kind of public equipment, the usage rate of these computers is very high, and the users' hygiene awareness is relatively low. Therefore, some experts say that the computer keyboard is even much dirty than the toilet.

According to experiments conducted by Australian researchers, the 80 public computers and personal computers investigated have a bacterial contamination rate of 100%. Bread crumbs, biscuits, coffee powder, tobacco ash, hair and other sundries hidden in the crevices. More than a dozen kinds of bacteria such as fungi, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis, and fungi have been cultivated after sampling with a cotton swab, which can be called a breeding ground for bacteria. Among them, 50% of public computer (notebook) keyboards and 20% of personal computer (notebook) keyboards contain Staphylococcus aureus, and once the bacteria enter the human body, it can cause serious infections such as pneumonia.

This is why we shares this how-to guide about sanitizing keyboard and recommend regular cleaning and disinfection to computer keyboards. If we don't disinfect the keys regularly, the keyboard will be covered with stains and become a home for viruses and bacteria, which will endanger our health.

How to Disinfect Computer Keyboard & Keys?

Before proceeding with this step, please make sure that your laptop or keyboard has been unplugged from the power cord and completely powered off, otherwise, electronic components may be damaged. In addition, this can also avoid data loss caused by accidental operations.

Things What You Need:

A hair dryer.
Disinfect wet wipes (also can use a soft cloth and isopropyl alcohol), or a UV wand.
Cotton swabs.
A Flat-head screwdriver.
Detergent or disinfectant solution.

Step-by-Step Instructions:

Step 1: Shake the Computer Keyboard
Turn the keyboard upside down, tap and shake it. In the process of shaking and tapping, you will find a lot of "stock" falling out of the keyboard: in addition to dust, there are also biscuit crumbs, bread crumbs, coffee powder, rubber crumbs, soot, hair, etc. When tapping the laptop keyboard, you need to turn the keyboard side down, and be sure to tap the keyboard lightly to avoid damage.
Step 2 : Blow Off Debris
Use a hair dryer to aim at the gaps on the keyboard keys and blow (note: do not use high-temperature gear) to blow off the debris attached to it, and then turn the keyboard down again and shake it. Blowing and shaking can be alternated with each other, which is more helpful for better cleaning.
Step 3 : Scrub and Disinfect the Keyboard Surface & Keys

Method 1. Sanitize keyboard with disinfection wipes
We can use disinfection wipes or a soft cloth dipped in isopropyl alcohol to clean and disinfect the keyboard. When cleaning, be sure to carefully wipe the five sides (top and four sides) of each key, and then wipe the other parts of the keyboard thoroughly. For particularly dirty keyboards, you can also use a cotton swab dipped in isopropyl alcohol to wipe the sides and gaps of the keys to effectively remove mold and bacteria in the gaps.

Method 2. Disinfect computer keyboard with UV Sterilizer Wand
Clean and disinfection are different. If you have cleaned the keyboard surfaces with a semi-moist soft cloth, you can also use an ultraviolet sterilizer wand to disinfect the keys and surfaces, instead of chemicals. Utilizing the principle of ultraviolet sterilization, the ultraviolet sanitizing wand can destroy 99.9% of bacteria, viruses and other microorganisms on the keyboard, without any chemicals. It can also be used to disinfect the cellphones, iPad, towels, bed sheets and etc.

Hereof, we take the AWESAFE UV Wand for example. This UV sterilizer is simple to use for keyboard sanitizing:

  • Fully charge it
  • Turn off the child lock
  • Unfold it
  • Press the function button to set the disinfection time
  • Start working
  • Use its ultraviolet rays to illuminate the computer keyboard and swipe it back and forth about 10 times.
Step 4 : How to Sanitize the Keyboard Keys Deeply?

If you want a deep cleaning of the keyboard, you have to remove the cap of each key. The keycaps of most external keyboards are detachable. For laptop keyboards, please check the brand and model of the laptop first to confirm whether its keycaps support disassembly, otherwise the keyboard may be damaged.

For a detachable keyboard, you can use a flat-head screwdriver to pry off the key caps, and proceed one by one from the corners to the middle part. Larger key caps such as the Space bar and Enter key are difficult to return to their original positions, so please don't disassemble them. In order to avoid forgetting the position of these button caps, it is best to take a picture of the keyboard layout with a camera or draw a sketch. After removing the key cap, you can soak it in detergent or disinfectant solution, and carefully scrub the keyboard base with a flannel or disinfectant paper towel. Be sure to wait for the keycaps and keyboard to dry before starting to install the keycaps.

Notes: Some people are accustomed to cleaning the keyboard with a damp cloth. However, although a wet cloth can remove some stains and viruses on the keyboard, most of the viruses will remain on the keyboard, continuing to endanger the health of computer users. At the same time, the moisture in the wet cloth is likely to seep into the cracks of the keyboard under the pressure of the scrubber, causing oxidation or rusting of the keyboard parts.

There is also a soft gel-like cleaning product on the market. Put it on the surface of the keyboard. After a little pressure, the dust on the surface can be "sticked" out. However, the inside of the keyboard is difficult to reach.

After reading the above four steps are about how to sanitize computer keyboard and keys, have you got some clues? Generally, the keyboard needs to be cleaned once every three months, so why not give your keyboard a bath now!
