Doorknobs and light switches are among the most frequently touched surfaces in any home or office. From opening doors to turning on lights, these everyday objects are exposed to countless hands, making them prime locations for the buildup of dirt, oils, germs, and bacteria. Whether you're concerned about hygiene due to a viral outbreak, or simply aiming to maintain a clean home environment, knowing how to properly sanitize and clean your doorknobs and light switches is essential. In this guide, we'll explore the best practices for sanitizing and cleaning these surfaces effectively, using a range of methods and products suited to different needs.

Why Sanitizing Doorknobs and Light Switches is Important

1. High-touch Surfaces

Doorknobs and light switches are considered high-touch surfaces because they are often used by multiple people in a short span of time. These surfaces can collect bacteria, viruses, dirt, and grime, contributing to the spread of germs and making them potential hotspots for illness.

2. Health and Hygiene

Germs from various environments, including dirt and bacteria, are transferred onto your hands each time you touch a doorknob or light switch. If you don't sanitize these surfaces, you may unknowingly bring those germs into your home or office, contributing to the spread of illnesses like the flu, cold, or other infections.

3. Maintaining Cleanliness

Regular cleaning of these surfaces not only helps improve hygiene but also contributes to the overall cleanliness and appearance of your home. It's especially noticeable in spaces that guests or visitors frequently interact with, such as entryways and common areas.

Materials Needed for Cleaning and Sanitizing

Before getting started, gather the following materials to ensure effective cleaning and sanitizing:

  • Disinfecting Wipes or Spray: These often contain ingredients like alcohol or bleach that kill bacteria and viruses.
  • All-purpose Cleaner: For general cleaning to remove grime, fingerprints, and dust.
  • Microfiber Cloth : Gentle on surfaces, microfiber cloths are excellent for wiping down doorknobs and light switches without leaving lint or scratches.
  • Cotton Swabs or Toothbrush: For cleaning hard-to-reach areas, such as the edges of switches and knobs.
  • Water: For rinsing and diluting cleaners when necessary.
  • Gloves: To protect your hands when using stronger cleaning products or sanitizers.

Step-by-Step Guide to Cleaning and Sanitizing Doorknobs and Light Switches

1. Turn Off the Power to Light Switches (Optional)

If you're cleaning light switches and you're concerned about safety, it's always a good idea to turn off the power at the circuit breaker. While this is not strictly necessary for routine cleaning, it's a precautionary step if you're using water or liquid cleaners.

2. Clean the Surface

  • For Doorknobs:

    • Dust and Wipe : Begin by dusting the doorknob with a dry microfiber cloth to remove any surface dirt. This prevents dirt from being smeared around when applying cleaner.
    • Apply Cleaner : Use an all-purpose cleaner or a disinfecting wipe to thoroughly clean the doorknob. Make sure to wipe down the entire surface, including the handle and any parts that come in direct contact with your hands.

  • For Light Switches:

    • Dust First : Start by dusting the area around the light switch with a dry microfiber cloth. Dust often accumulates around the edges of light switches, and wiping it off first prevents it from mixing with cleaning solutions.
    • Use Cleaner or Wipes : Apply a small amount of all-purpose cleaner or disinfectant spray to a microfiber cloth, then gently wipe the switch plate. Avoid spraying the cleaner directly on the switch to prevent moisture from entering the electrical components.

3. Pay Attention to the Edges and Crevices

Both doorknobs and light switches often have tiny crevices or edges where dirt and grime build up over time. Use a cotton swab or a small, soft brush (like an old toothbrush) to clean these areas thoroughly. This is especially important for light switches, as grime can accumulate in the ridges and around the switch itself.

4. Sanitize the Surface

After cleaning, you should sanitize both doorknobs and light switches to eliminate any remaining germs:

  • Disinfecting Wipes or Spray : Wipe down the surface with a disinfecting wipe or apply a disinfecting spray that contains at least 70% alcohol. This helps kill any bacteria or viruses present.
  • Let it Dry : Allow the surfaces to air dry for several minutes to ensure the disinfectant has time to work effectively. If you're using a commercial disinfecting spray, follow the manufacturer's instructions for the required contact time.

5. Inspect for Mold or Stains

Check for any signs of mold, mildew, or stubborn stains. If you notice these issues, you may need a more targeted approach. For mold, a mixture of water and vinegar or a diluted bleach solution can help to remove it. However, be careful with bleach as it can damage certain finishes, so always test it in a small, inconspicuous area first.

Tips for Maintaining Clean Doorknobs and Light Switches

  1. Routine Cleaning: To keep these high-touch areas clean and hygienic, make it a habit to wipe down doorknobs and light switches at least once a week. During cold and flu season or after any illness, sanitize them more frequently.

  2. Use Microfiber Cloths : Always use a microfiber cloth when cleaning to avoid scratching or damaging the surface. They are effective at trapping dust and dirt without leaving lint behind.

  3. Be Mindful of the Finish : Doorknobs and light switches come in a variety of materials, such as brass, chrome, plastic, or painted surfaces. Some cleaning agents, like harsh chemicals or abrasive scrubbers, may damage certain finishes. Always check the manufacturer's instructions for the best cleaning practices based on the material.

  4. Disinfect After Visitors or Guests: If you've had visitors in your home or office, it's a good idea to sanitize the doorknobs and light switches afterward, as these surfaces are commonly touched by multiple people.

  5. Keep Cleaning Products Handy : Keep disinfecting wipes or a bottle of cleaner near entryways or in common areas. This makes it easier to quickly wipe down high-touch surfaces as needed.

Conclusion

Regular cleaning and sanitizing of doorknobs and light switches are essential steps in maintaining a clean and hygienic environment. By following the simple steps outlined above, you can effectively remove dirt, grime, and germs from these frequently touched surfaces. Whether you're cleaning for general maintenance, or taking extra precautions during flu season or a viral outbreak, a little attention to these surfaces can go a long way in ensuring the overall cleanliness and health of your living or working spaces.
