Do you know why it’s important to disinfect your kitchen sponges regularly?

Kitchen sponges can become filled with harmful bacteria and microorganisms since they’re used to do so many cleaning chores. In fact, some studies have shown that sponges are one of the most contaminated home items, even more so than bathrooms.

Why is this?

Moisture and food waste in sponges create an environment conducive to the proliferation of many pathogens.

Therefore, it’s essential to learn different methods you can use to disinfect them, preferably after every use. In this article, discover five tricks to disinfect your kitchen sponges.

Why You Should Disinfect Your Kitchen Sponges

Kitchen sponges are used for washing dishes and other utensils. Due to what they’re made of, they easily release the fat and food waste that adhere to dishes.

They’re very dirty because the moisture and microcracks that make them up are perfect homes for bacteriasuch as E. coli., Salmonella, or Campylobacter, among others. They proliferate a lot faster in this environment and can survive for up to two weeks.

When you use them to wash dishes, many of these microorganisms can spread among different utensils, increasing the risk of infection.

Fortunately, all you have to do is replace them on a regular basis or use some formulas to keep them clean.

Here are five kitchen sponge disinfecting solutions.

1. White Vinegar

White vinegar.

This product produces an acidic pH that favors the elimination of many bacteria and waste.

White vinegar is one of the best natural products to disinfect your kitchen sponges. Due to its concentration of organic acids, it alters the environment microorganisms need to proliferate. In addition, it eliminates odors and grease.

How to Use It

  • First, boil a cup of water.
  • Then, mix in a cup of white vinegar.
  • After that, soak the sponge in the mixture for approximately 20 minutes.
  • Wring it out to help remove dirt.
  • If you consider it necessary, rinse it out with soap and water.

2. Liquid Dish Soap

Liquid dish soap can disinfect sponges due to its properties. However, for a deeper cleaning, it’s best to combine it with boiling water.

What to Do

  • To begin, dissolve a tablespoon of liquid dish soap in a bowl of boiling water.
  • Then, soak the sponge in the mixture (be careful not to burn yourself).
  • After approximately 20 minutes, rinse and remove any waste.

3. Microwave

This appliance can be used to disinfect kitchen sponges due to the temperatures it reaches.

Microwaves help eliminate pathogens in kitchen sponges. High temperatures alter their characteristic moist environment, therefore preventing microorganisms from growing.

What to Do

  • First, please note that some sponges are made from synthetic materials that may melt when exposed to high temperatures. Therefore, before using this method, it’s best to soak the kitchen sponge in a bowl containing water and vinegar.
  • Then, put the bowl in the microwave for two minutes.
  • If your sponge smelled bad or musty, this method will eliminate any odor instantly.

Be careful when you take the bowl out of the microwave, as you could burn yourself.

  • Then, rinse them with cold water and liquid soap.

5. Tea Tree Essential Oil

Tea tree essential oil.

Due to its antimicrobial properties, tea tree can help control bacterial growth.

Although this ingredient is known for its therapeutic applications, it’s a great way to eliminate microorganisms on different surfaces. It can even eliminate bad odors.

What to Do
