Is It Safe to Clean a Microwave with Bleach?

Bleach is one of the most effective cleaning products in your household due to its vital ingredient: Sodium hypochlorite. Bleach can be used to remove tough stains, whiten clothing, sanitize toilet rooms, and sinks. Besides, the smell of bleach after usage is a refreshing smell and a good indicator of cleanness.

However, it is a myth that bleach can clean things. Bleach actual function is disinfecting germs and bacteria and discolor clothes. Therefore, if there is a stain on a sink, bleach products won’t remove it but can kill the germs and oxidize the stain on that surface.

Since microwave heat already kills bacteria, stains can be easily removed by other mild cleaning products such as baking soda, vinegar, and wet cloth.

Moreover, bleach is also a strong disinfectant product. It can damage some surfaces. When scrubbing on the plastic part of the microwave, bleach can discolor and make it brittle.

Serious issues can also happen if you put bleach on a heated surface. This causes a hazardous reaction generating Chlorine, which can be irritating to your eyes and nose.

Therefore, we recommend that you should avoid using bleach to clean microwaves and try these safer and non-chemical ingredients in our guidelines below.

How to Clean a Microwave Safely?

So, bleach is not an outstanding choice to clean a microwave. What alternatives can you actually use?

Here are Some Familiar Ingredients That Possibly Always Lie in Your Kitchen:

  • Vinegar is a great ingredient for cleaning, sanitizing, and deodorizing any foul food stains. You can use either white vinegar or apple cider for cleaning.
  • Lemon juice (or Lemon essential oil) contains acidity, and grease-cutting oil can help break down any grease on your microwave. In addition, lemon also gives a scent of nature and freshness.

But how do we utilize these ingredients?

Here are The Simple Steps to Clean a Microwave Safely:

Step 1: Preparation

Fill warm water and white vinegar or lemon juice in a microwave-safe bowl, containing 4 cups of liquid.

Then put a wooden spoon in the bowl and place all of them inside the microwave.

Step 2: Microwave

This is probably the best part of this process. Set your microwave for a few minutes and turn it on. The wooden spoon will keep the water from overheating during the process.

It depends on your microwave’s wattage that you set a reasonable time. For example, for a 1200-watt microwave, it is recommended to 1-1,5 minutes. For a 700-watt microwave, the time could be longer to around 2 minutes.

At this step, the nice steam coming from heated water will save you from most of the heavy scrubbing.

Step 3:

When the microwave finishes, keep the door closed for 3 minutes so the steam can hit all sides of the microwave and wait for the microwave to release all the heat.

Then carefully take the bowl out.

Step 4:

Get a cloth and start wiping the inside, the door, and outside of the microwave. At this time, the steam will soften out all the splatters and stains, and you can easily wipe them out.

Step 5:

Enjoy your clean-as-a-new-pin microwave!
