If you don’t have hydrogen peroxide available try out another process. The following method will be very helpful.

Follow the steps thoroughly and wait for the amazing result.

  • Remove The Soil

The first step involves simply removing the soil from the pot. This step helps to clean the pots easily. So, take the plant and the root ball out of the clay pot.

By the way, do not try to take out wet soil. You will end up smearing mud here and there. First, allow the soil to dry out and then remove it clearly.  

  • Scrub The Dirt Away

Then, you have to clean all the remaining soil as much as you can. You can also take the help of a scrubbing brush to clean it thoroughly.

Once you are done, rinse the pot in clear water. Using the scrubbing brush inside and outside, clean the crusty gunk as much as you can.  

  • Soak The Pots In Water/Vinegar Solution

In the next step, you can use the magic power of vinegar. Apart from the fungal molds, minerals from soil and water also get deposited in the pots.

The marks of minerals become vibrant with time.

Vinegar does a great job to dissolve the marks. In a large tub, pour water to the rim of the tub. Then add two to three cups white (5% acidic) vinegar into the water.

Now, soak the pots in the solution for at least 15 minutes.   

Now, wait for 15-20 minutes. Times up!

Now take out the pots, what’s the result? In an ideal condition, the marks get dissolve. However, if the marks persist, you have to try out another method.  

Do you have baking soda available in your home? It’s time to take out in a good portion. Cleaning Terracotta pots with baking soda helps to remove additional marks of molds.

Sometimes, stubborn salt marks persist after the wash. In that case, make a paste banking soda and water. The consistency should be like a hand lotion.

Now, smear the paste on the build-up. Wait for another 15 minutes. Then use the scrubbing brush gently on the build-ups.   

  • Wash The Pots With A Dishwasher

Finally, the marks are gone! Now, you will see clear pots without any debris and white marks on them.

However, in the soaking process, you might have lost the subtle shining texture it had. So, it’s time to get back the texture again.

Here I never recommend using soap. However, I have seen many gardeners use it. But, my experience and preference suggest you use the liquid dishwasher.

Wash the pots again with the dishwasher properly. You will find a light gleam texture after the wash.  If you are happy with the previous result, you can skip this step.  

Now, let’s see how it’s easily can be done using vinegar from this video.

Cleaning Terracotta Pots Using Hydrogen Peroxide

The easiest method to kill the mold is by applying hydrogen peroxide. You need to pour 3% in a spray bottle and sprinkle it outside the pot.

Let it sit for a few minutes. Then, you will see a clear reaction against the molds. Wash the outside with water and a scrubbing brush.

Try not to attempt the process under direct sunlight. Otherwise, the solution would end up becoming ineffective.  

Cleaning Terracotta Pots Using Bleach Water Solution

The above-mentioned ideas are simple and pocket-friendly. Apart from the simple way, you can also try out another alternative.  

When cleaning of the molds is concerned, bleach water also works great. In that case, instead of soaking the pots in vinegar solution, you have to use bleach water solution.

However, the ratio of bleach plays a crucial role here. ¼ cup of bleach in 5 gallons of water goes perfect. Let the pots soak for 30 minutes.

That’s all!  

If you are using bleach, you should be careful from the very beginning.  Wash 3-4 times with water after removing it from the solution. Then, let the pots sundry for a couple of hours.

Moreover, you should wait at least two to three days before putting back the plants. Basically, it will ensure the smell and the chemicals of the bleach are completely obliterated.

Otherwise, the effect of bleach can damage sensitive plants.
