What Happens if You Microwave Dish Soap?

We’ve all been there once, curious about what would happen if we put something in the microwave that we weren’t supposed to.

While it’s tempting to find out, it’s important to remember that not all experiments are safe.

So in this article, we’re looking at what you should expect to happen if you microwaved dish soap. When you put dish soap in the microwave, it turns into a bubbly volcano.

The water molecule in the soap interacts with microwave radiation to heat the soap, causing the water and air in the soap also to get heated up.

As the trapped hot air and steam build up in the soap, they push their way out, making it bubbly.

These bubbles expand quickly and can cause a fire in the microwave if they come into contact with the heating element.

And while microwaving dish soap is fun at home, this experiment should not be done by children under the age of 16 because it can be very dangerous.

Also, before you microwave any dish soap, ensure that the container is microwave-safe so that even when it explodes, it doesn’t hurt anyone.

Dish soap shouldn’t be microwaved for more than five minutes because that’s when the chemical structures start breaking down.

Safety Precautions to Take Before, During, and After Microwaving Dish Soap

Microwaving dish soap could be for experimental purposes, or you could have left it in the microwave by mistake.

Less precaution can be given to it if the dish soap was mistakenly left in the microwave, but in the case of an experiment, some safety measures should be cautiously put in place.

Before microwaving dish soap, it is important to take a few safety measures.

Microwaving dish soap can be dangerous as harmful chemicals can be released into the air. These chemicals can be irritating to your lungs and can cause difficulty breathing.

Also, dish soap can easily splatter and cause burns. If you experiment with microwaving dish soap, be sure to do it in a well-ventilated area and wear protective clothing.

And to start with it, remove all food from the microwave. Do well to remove the dish soap from its original container and place it in a microwave-safe bowl.

And when microwaving the dish soap, start on a low setting and increase the power if needed.

The longer it’s microwaved, the more bubbles will form. It is best to microwave dish soap for no more than five minutes at a time before checking on it again.

After microwaving dish soap, clean the inside of the microwave with vinegar so that any residue will not contaminate any other foods when they are cooked.

A light scrubbing might also be necessary after the dish soap has been microwaved.

Can I Melt Soap in the Microwave?

You might have a bar soap or pieces of soap you would want to melt and remold or use for other things.

Yes, soap can be melted in the microwave, but be careful because the liquid may splatter and create a mess.

Soap is made up of fats and oils, which are long-chain molecules. When microwaves hit these molecules, they cause them to vibrate.

This vibration produces heat, which can cause the soap to melt. The longer it’s microwaved, the faster it will melt.

You should always keep an eye on the soap while in the microwave so that you don’t burn yourself with scalding hot bubbles or get splattered with a sudden eruption of suds.

Remember, it’s always better to err on caution when dealing with open flames. Be sure to stand back and watch the soap carefully as it melts.

If your microwave has vents at the top, ensure they’re not blocked by your hand or any other object; this would prevent any vapors from escaping and letting out some steam.

Depending on how much soap you’ve used, the whole bar might take a few minutes to melt. Once it’s all liquefied, carefully remove it and pour it into your preferred container.

Is it Safe to Melt Soap in the Microwave?

A microwave is a great option if you’re looking for a quick and easy way to melt the soap.

However, you should take a few safety precautions to ensure a safe and successful melting experience.

  1. Use a microwave-safe container because microwave radiation can cause other materials to melt or warp.
  2. Don’t overheat the soap; start with a short melting time, such as 30 seconds, and then gradually increase the time if necessary. Three minutes on high should be enough to get it fully melted.
  3. Make sure that the container has enough room for expansion so that the liquid doesn’t overflow when it starts bubbling and popping.
  4. Place another glass of water in the microwave. This will help redirect the microwave radiations to it to generate more to speed up the melting process of the soap.


When microwaving dish soap, the molecules heat up and create bubbles. The bubbles grow until they eventually pop, causing the suds to collapse.
