bathroom sink and towels - most germs spots in home

The 7 most germ-ridden spots in your home…revealed!

Maintaining a clean and germ-free home is important for the health of your family as well as maintaining a nice home you enjoy spending time in. Have you ever wondered which spots in the home are prone to gathering the most germs? In this blog, we have revealed the top germiest spots in your home and the best way to keep them spick and span!

1. Kitchen Countertops

Kitchen countertops are one of the most frequently used surfaces in the home, and they can harbour a variety of harmful bacteria. Raw meat, fruits, vegetables, and other ingredients come into contact with these surfaces, leaving behind potential contaminants which can breed over time.

To keep your kitchen countertops clean, spray them frequently with a disinfectant spray such as Cert. and wipe away any bacteria with a clean cloth. If you are using microfibre cloths or sponges, remember to replace or clean these regularly to avoid spreading more bacteria over the sides when you wipe.

2. Bathroom Sink and Taps

The bathroom sink, taps, and vanity area are breeding grounds for bacteria and other germs. These surfaces are exposed to water, toothpaste, and other products which can create a moist environment for bacterial growth. Spray from a flushing a toilet nearby can also get onto sinks and surrounding items more easily than you might think (which is why it is recommended that you close the lid each time you flush).

To keep these surfaces clean, wipe them down daily with a disinfectant cleaner such as Cert. Pay extra attention to taps and tap handles as they are frequently touched and can accumulate germs very quickly.

3. Doorknobs and Light Switches

Doorknobs and light switches are high-touch surfaces that often go unnoticed when it comes to cleaning. These areas are frequently touched by multiple people, making them hotspots for germ transmission.

To effectively clean and disinfect doorknobs and light switches, spray a disinfectant like Cert onto a dry cloth and immediately wipe over the light switch. You could lightly directly spray onto the switch but make sure you do not heavy-wet any electrical items. Make it a habit to regularly clean these surfaces, especially during cold and flu seasons.

4. Remote Controls and Electronics

Remote controls, gaming controllers, and other electronics are items we frequently handle without considering their potential germ load. These items can accumulate bacteria and viruses, as they are touched by various individuals and rarely cleaned.

To clean electronic surfaces safely, start by removing batteries or power sources. Then, wipe the surfaces with a microfiber cloth which has been sprayed with a disinfectant spray such as Cert. Be careful not to oversaturate the surfaces to avoid damage.

5. Kitchen Sponge and Dishcloth

While they might seem harmless, your kitchen sponge and dishcloth can be teeming with bacteria. These items provide the perfect environment for germs to thrive, as they are often damp and encounter various food particles.

To minimize the spread of bacteria, replace your sponge regularly and sanitise it frequently. You could microwave a damp sponge for 2 minutes to kill bacteria, or run it through a hot wash or dishwasher.

6. Bathroom Towels

Bathroom towels are another often overlooked source of germs. They absorb moisture and dead skin cells, creating an ideal breeding ground for bacteria. Additionally, if towels are shared among family members, the risk of cross-contamination increases.

To combat this, wash your towels frequently in hot water with a decent washing detergent. As a general rule, it is recommended to wash towels every 3-4 days.

7. Handrails and Staircase Railings

Handrails and staircase railings are touched by multiple people throughout the day, making them highly susceptible to germ accumulation. To keep them clean, spray and wipe them down with a disinfectant spray such as Cert.
