Will Dish Soap Kill Mold? (Dishes, Hands, Walls, Floor)

can Dish Soap Kill Mold

Mold in your home not only poses a health risk but also is an ugly scar on whatever surface it appears. It has to be gotten rid of immediately.

People are concerned about eradicating mold from their homes from its very roots. And for this, many don’t want to spend money on expensive mold removers. Many prefer to use the good old dish soap

But can Dish soap kill mold? We’ll find this out in this article! We’ll also talk specifically about mold on dishes, hands, walls, floor, and wooden surfaces. We’ll show you the effective step-by-step methods by which you can remove mold from these surfaces.

Will Dish Soap Kill Mold?

Dish soap will not kill mold. Dish soap will however clean mold. There’s a big difference between cleaning mold and killing mold and your choice determines the kind of solution you will be going for.

When you use dish soap and water on mold, especially mold that developed on non-porous surfaces, the mold dislodges and you can get it off the surface easily.

When this happens, the mold doesn’t die, this just enables you to remove it from wherever you found it.

The mold can still grow back on that surface because the spores will still be alive and the one you removed can still cause allergies if you don’t dispose of it properly.

Dawn dish soap, however, kills mold but it is not as effective as other products we know and it’s not advised where mold has grown in large numbers.

Dish soap is however vital when killing mold with other products like bleach.

These products that are known to be very effective in killing mold may not work as well if dish soaps are not included in their usage. So dish soaps aren’t useless when it comes to mold killing.

Why is Dish Soap Necessary for Mold Killing?

Mold-killing chemicals like bleach cannot kill mold on porous surfaces. This is because the pores of the mold will be rooted in the material and bleach won’t be able to penetrate the surface to kill them.

So applying a bleach solution would only kill the mold on the surface, and the water that penetrates the surface will only aid the pores in growing faster.

This is why dish soap is needed. Dish soaps contain what is called surfactant. This breaks the tension of the porous surface where the mold is, dislodging the spores and allowing the bleach or any other product to penetrate and kill the mold.

It’s like the surfactant makes way for the product to do a deep killing and removing of the mold.

Before we go into the different methods of killing mold with dish soap, you should note these.

1- Cleaning mold can be dangerous so protect yourself first, before cleaning. Some of the products we’ll be combining with dish soaps can also be harmful.

So wear old clothes, long rubber gloves, goggles, and a nose mask always.

2- Mold appear because of moisture. Don’t just kill the mold and leave. Look for the source of the problem; why the place has a lot of moisture, and solve that problem.

That’s a more permanent way of ridding yourself of mold.

3- If you are dealing with black mold or mold that has affected a very large area, it’s better to call professionals.

Does Dish Soap Kill Mold on Dishes?

Dish soap will clean and remove mold from dishes without stress. Dishes have non-porous surfaces so it’s easy to kill or clean mold on them. The mold doesn’t have roots or spores you can’t see, so you only have to deal with the surface level.

Now let’s discuss the method of doing this in detail.

Method 1: Dish Soap + Hot Water

This method works best if the mold hasn’t stayed on the dishes for long.


1- Hot water
2- Dish soap
3- Sponge


STEP 1: Plug your sink and fill it with 1 gallon of hot water.

STEP 2: Add some drops of dish soap to the water. Enough to make it foam. If the dishes can’t be destroyed by hot water, put them into the soapy hot water and leave them. If the dishes can be destroyed, let the water cool a bit before putting the dishes.

STEP 3: When the water has cooled down, take a sponge or pad and scrub the dishes. The mold will easily remove and your dishes will be free.

STEP 4: Unplug the sink and let the water drain out. Now wash the dishes again with normal water and dish soap and rinse with warm water. Dry the dishes when you are done.

Method 2: Dish Soap + Vinegar / Bleach

If the dishes have been moldy for a long time, the first method may not work. You need something stronger. But you still need dish soap like we earlier explained.


1- Vinegar/bleach
2- Water
3- Dish soap
4- Bristled brush.
5- Sponge


STEP 1: Dishes are non-porous so you don’t need to use the dish soap first. A surfactant isn’t needed.

STEP 2: Spray your dishes with white vinegar or soak them in a bleach solution. 1 cup of bleach to 1 gallon of water is a perfect mix.

STEP 3: Let the vinegar sit on your dishes for like 5 minutes. If you’re using a bleach solution, 5 minutes is also enough for the dishes to soak.

STEP 4: Use the bristle brush to scrub the dishes thoroughly. The acidic nature of the vinegar/bleach would have killed the mold, making it easier to remove.

STEP 5: To make sure the mold is all gone. Use a sponge and some dish soap to wash the dishes in warm water. This also helps to get rid of the vinegar/ bleach residue.

STEP 6: Rinse with cool water and dry.

Does Dish Soap Kill Mold on Hands?

Dish soap will not kill mold on your hands but can help get rid of it before it can harm you. Some mold types have toxins that can irritate your skin, causes rashes, and even infect you if you have open wounds on your hands.

So getting rid of the mold if your hands come in contact with them is important. Dish soaps can help with that.

How to Use Dish Soap on Hands?

STEP 3- Rinse your hands again under running warm water for like 10 seconds, and dry with a soft clean towel.

Will Dish Soap Kill Mold on Walls?

Yes, in addition to other products, dish soap can be used to kill mold on walls. Walls are porous surfaces so the surfactant in the dish soap s needed.

Now, let’s see how to kill mold on walls with dish soap.

Method 1: Dish Soap + Bleach

Bleach works well in killing and removing mold not just from dishes but from walls too. It also prepares the wall for recording or repainting.

Remember that bleach can destroy your fabric and irritate your skin. So wear old clothes, long rubber gloves, and a nose mask.

STEP 3: Prepare a bleach solution. 1 part bleach to 3 parts water is needed for this. Pour this solution into a spray bottle and spray your wall thoroughly. Ensure the moldy wall is well saturated with the bleach solution.

STEP 4: Allow the solution to sit for like 10 minutes, then scrub the wall with a brush, taking care not to damage the wall.

STEP 5: Rinse the wall with water when you are done and allow it to dry. If the wall is indoors, open all windows, and turn on the fans so it can dry faster.

Method 2: Dish Soap + Borax

Borax is a non-toxic product that you can safely use to kill and prevent mold in your home. Not only will it kill the mold on your wall, but it also will prevent new mold from growing on that wall because of its anti-fungal properties.

This method is great for extensive mold infestation.


1- Borax
2- Bucket
3- Sprayer
4- Dish soap
5- Brush


STEP 1: Pour 1 gallon of hot water into a bucket and add 1 cup of borax into it. The hot water helps the borax dissolve and mix properly with the water.

STEP 2: Pour the solution into a sprayer when it cools down a bit and spray the moldy wall. The borax solution kills the mold so spray it generously.

STEP 3: Allow the borax solution to sit on the wall for about 5 minutes, then scrub with a brush. The mold will easily dislodge from the walls. Leave it for 1 minute.

STEP 4: Put some dish soap in a bowl of warm water. Use a scrub pad to scrub the wall clean using warm soapy water. Then rinse the mold and grime off the wall water.

STEP 5: After rinsing the wall and it looks clean, spray the wall again with borax solution lightly. This will ensure mold doesn’t grow on the wall again. Then let it dry off.

For killing mold on concrete/cement block basement walls, white vinegar or Hydrogen peroxide is a better option.
