How to Clean a Computer Keyboard: Your Step-by-Step Guide

by

Maintaining the cleanliness of a computer keyboard is an important aspect of computer hygiene, as it can harbour more germs than an average toilet seat. Keyboards, an integral component for the interaction with desktops, laptops, and some tablets, often fall victim to accumulated dust, crumbs, and spills, which can not only affect the device’s functionality but also pose health risks through the spread of bacteria. It is therefore crucial for users to regularly clean their keyboards to ensure both the longevity of the device and their personal well-being.

The approach to cleaning a keyboard varies based on the type of device and the level of dirt build-up. With electronics such as phones and smartwatches, gentle wiping with a microfibre cloth might suffice, but keyboards often require a more thorough process. This involves removing debris with tools like compressed air or cleaning gels, cleaning the surface and individual keycaps with isopropyl alcohol, and deploying methods to sanitise effectively. Each device has its own set of cleaning recommendations, and it is essential for the user to be familiar with the manufacturer’s guidelines to avoid damage.

Cleaning should be done with the keyboard unplugged and powered off to prevent any electrical hazards or short-circuiting. For laptop keyboards, extra care must be taken to prevent liquids from seeping in and damaging the integrated components beneath the keys. Tablets and phones, often featuring on-screen keyboards, may require less rigorous cleaning regimes, yet should be cleaned with approved wipes or cleaning solutions designed for electronics to avoid damaging their sensitive touch screens.

Preparing Your Workspace

Before one begins the task of cleaning their computer keyboard, it is imperative that they prepare an appropriate workspace. This helps in executing a safe and efficient cleaning process.

Gathering Cleaning Supplies

One should assemble all necessary cleaning supplies before starting. The items typically include:

  • Microfibre cloths: Effective for gentle cleaning without leaving fibres behind.
  • Isopropyl alcohol: Suitable for disinfecting and cleaning without causing damage.
  • Compressed air can: Useful for dislodging debris from between keys.
  • Cleaning swabs: To clean hard-to-reach areas.
  • Cleaning brush or old toothbrush: For brushing away crumbs and dirt.

Powering Down and Disconnecting

To avoid electrical damage or unintended inputs, one needs to power down the computer and unplug the keyboard. For wireless keyboards, it is best to remove batteries as well. The keyboard should not be cleaned while connected to any power source.

Surface Cleaning

A clear and spacious desk surface is recommended for keyboard cleaning. Here are the steps one should follow:

  1. Lay a clean, flat cloth on the desk.
  2. Gently place the keyboard on the cloth.
  3. Start with light dusting to remove surface debris.

Using a cleaning area devoid of liquids or any peripheral devices is crucial to prevent any accidental damage.

Cleaning the Keyboard

Maintaining a clean keyboard is crucial for its longevity and functionality. The process involves removing loose particles, deep cleaning to tackle grime, and disinfecting to kill germs.

Removing Loose Debris

To begin, one should ensure the keyboard is unplugged and turned off. A can of compressed air can be directed between the keys to dislodge and remove particles like dust, crumbs, and other debris. Tilting the keyboard at various angles and gently tapping it can help in knocking loose any stubborn detritus.

  • Tools:
    • Compressed or canned air
    • Handheld vacuum (optional)
    • Soft brush (e.g., keyboard brush or unused toothbrush)

Deep Cleaning Techniques

For a more thorough clean, carefully pry out the keys using a flat tool such as a screwdriver or a plastic opening tool. A toothpick may be used to remove any compacted dirt within the crevices. After keys are removed, a damp microfibre cloth can be used to wipe down the base of the keyboard. It’s important to ensure the cloth is not overly wet to prevent liquid damage.

  • Step-by-Step Process:
    1. Remove keys carefully.
    2. Pick out compacted dirt with a toothpick.
    3. Gently wipe the surface with a slightly damp microfiber cloth.

Disinfecting the Keys

Once the keyboard surface is cleared of particles and grime, it’s advisable to use disinfectant sprays or wipes to sanitise the keys and prevent the spread of germs. One should ensure that the product used is suitable for electronics to avoid any damage. After applying the disinfectant, the keyboard should be left to air dry before reassembling or using it again.

  • Products:
    • Disinfectant sprays suitable for electronics
    • Disinfectant wipes

Remember to conduct regular cleaning to not only keep the keyboard functioning optimally but also to maintain a germ-free environment.

Special Considerations

When cleaning keyboards, it’s vital to consider the specific types of keyboards in use. Different keyboards require unique approaches due to their construction and materials.

Laptop Keyboards

Laptop keyboards are generally more sensitive due to their integrated nature in the laptop. They don’t tolerate high volumes of liquids and are not as easy to dismantle for cleaning. Therefore, one should turn off the laptop and disconnect any power sources before cleaning. Use a soft brush or compressed air to remove loose debris from between the keys. For disinfecting, lightly dampen a lint-free cloth with isopropyl alcohol and gently wipe the keys without allowing any liquid to seep underneath.

Mechanical Keyboards

Mechanical keyboards, favoured for their tactile feedback, can often be more durable than their membrane counterparts. However, they still require careful cleaning. Users can typically remove the keycaps to access the area underneath where dust and grime accumulate. Cleaning here can involve using a keycap puller to remove keys, and a cleaning solution applied with a cotton swab. One should be mindful not to use liquids directly on the keyboard’s circuitry. Compressed air can also be utilised to dislodge any particles between the switches.

Maintenance and Care

Maintaining a computer keyboard requires regular cleaning and proper storage to ensure its longevity and functionality. Adhering to these practices minimises the build-up of dirt and prevents damage.

Regular Cleaning Schedule

Daily to Weekly:

  • Dry Wiping: Use a microfibre cloth to gently wipe the surface of the keys and remove dust.
  • Shaking: Hold the keyboard upside down and shake lightly to dislodge crumbs and debris.

Monthly:

  • Deep Cleaning: Remove keycaps carefully with a keycap puller and clean them in soapy water; rinse well to avoid soap residue.
  • Crevice Care: Employ cotton swabs lightly moistened with isopropyl alcohol to tackle grime in the crevices.

Post-Spills:

  • Immediately turn the keyboard upside down to prevent moisture from seeping into the circuitry.
  • Use paper towels to blot away the liquid and clean sticky residue with a cloth damped in isopropyl alcohol.

Proper Storage Practices

  • Avoiding Moisture: Store keyboards in a dry environment to prevent moisture damage.
  • Pet-Free Zones: Keep keyboards away from areas frequented by pets to reduce fur and dander accumulation.
  • Physical Protection: Cover the keyboard when not in use to protect against dust and accidental spills.
  • Keycap Safety: Ensure that keycaps are dry and gunk-free before re-attachment after cleaning.

Remember to handle laptop keyboards with extra care, avoiding excessive moisture and rough cleaning that could damage sensitive components.
