How To Disinfect The Germiest Places In Your Home

Contrary to popular belief, the toilet isn’t the germiest place in the home. In fact, it doesn’t even make the top 10 list for germiest places in any given home. According to the National Sanitation Foundation, the kitchen wins the award for the germiest spot in the home. Yeast, mold, and coliform bacteria (think e Coli and salmonella) all happily make their homes in the kitchen, which is why you need to disinfect the surfaces in this room regularly to remove germs and prevent illness. 

Bleach – An Ideal Disinfectant

Bleach is a great disinfectant as it effectively kills most household germs. Simply mix a solution of bleach and water in a spray bottle, spray the surface, and wipe. 

Note: Bleach isn’t always the right disinfectant for the job. Some alternatives include vinegar, disinfecting wipes, and hot, soapy water. Let’s look at some of the germiest places in the home and learn how to disinfect them. 

Dishtowels And Sponges

Dish towels and sponges harbor germs and bacteria like a… sponge. Follow these tips to keep your kitchen sponges and dish towels germ-free. 

1. Microwave sponges for two minutes daily to kill bacteria. 

2. Replace your dishtowels with a clean one every other day. 

3. Wash dish towels on the sanitizing cycle in your washer.

4. Replace sponges once a week. 

The Kitchen Sink

The second germiest place in the home is often the kitchen sink. This is because, in addition to washing dishes there, many people use it to defrost and rinse raw meat. Simple dish soap isn’t enough to kill germs, however, so scrub your sink and disinfect the drains using a solution of bleach and water at least twice a week. 


The bathroom is home to a plethora of germs and viruses, leaving your toothbrush and toothbrush holder at risk for harboring potential sickness. This is especially true if you store these items near the sink or toilet. 

Disinfect the toothbrush holder by placing it in the dishwasher and soak your toothbrush in an anti-microbial mouthwash at least once a week to remove germs. Finally, store your toothbrush and toothbrush holder away from the sink and toilet. 

The Coffee Maker

Although most coffee makers heat water to a temperature hot enough to kill germs, they still foster a moist environment that’s just right for bacteria and germs to grow. 

Wash the coffee pot and any removable parts in the dishwasher daily and wipe down the machine surface itself with a disinfectant wipe. Once a month, run a brewing cycle of white vinegar followed by several subsequent brewing cycles of clear water to clean the inside of the machine. 

Cutting Boards

Most experts agree that cutting boards are probably the germiest surfaces in the home. This is because they are often used to cut raw meat. To disinfect a cutting board:

  • Place it in the dishwasher after use or wash with warm soapy water. 
  • Soak in a solution of 5 tbsp. bleach to one gallon of water. 

The home can be a germy place, but if you follow the tips above, you can disinfect the germiest areas.
