How to Remove Mold From Your Shower Sealant

Share Post:

Let’s be frank — mold is one of the worst things that you can see in your home. And while mold spores can usually be found all over the house, they mostly thrive in moist environments, like your shower. If ignored, mold can spread quickly, stick to your shower sealant and grow behind it. As a result, you will have to act fast and clean every part of your bathroom, especially the caulk. Luckily, we are here to show you how to remove mold and prevent its growth without damaging the sealant.


Ammonia spray is extremely effective against mold and shouldn’t damage your shower caulk. Simply, mix ammonia with some water in a small container and pour it inside a spray bottle with a funnel. Then, spray it on the bathroom caulk and leave it for about 10 minutes to soak in. Afterward, scrub the caulk until mold starts coming out and use a cloth to dry the area. If the mold persists, repeat the procedure a few times until you manage to get rid of it all.

It’s also important to remember that ammonia is dangerous to your health, so you shouldn’t breathe it in. Therefore, you need to wear a respirator or open your bathroom windows when cleaning using ammonia. Also, avoid spilling ammonia on your skin by wearing gloves, as ammonia could cause skin rashes.


Borax is a cleaning agent that has been used for decades against all types of stains. Yet, many people don’t know that you can also use borax to remove mold from sealants and other surfaces. Just mix borax with water, apply the solution directly to mold and wait 5 minutes. Then, clean the area to reveal your mold-free shower sealant.

Hydrogen Peroxide

Last but not least, we have hydrogen peroxide, which is an environmentally friendly way to get rid of mold. For this method, you should use hydrogen peroxide with a concentration of 3% and place it in a spray bottle. Next, spray the compound on the caulk and let it sit for 10 minutes before scrubbing. Once that’s done, dry the area thoroughly with a paper towel or cloth rag.

Final Thoughts

Overall, getting rid of mold from your shower sealant can seem quite a hassle, especially if it’s your first time. However, with a bit of care and attention, you can easily remove it using a variety of compounds. Just remember to avoid skin contact and thoroughly aerate your bathroom before using it again.
