Mould buildup in the sealant is one of the hardest places to clean, especially if it’s left there for months or years. Once it’s there, even with a good amount of elbow grease you may not be able to remove it. Sometimes, despite regularly cleaning your bathroom tiles, mould can still show up on the sealant. Knowing the right cleaning method can save you a lot of time and troubles. 

In this guide, you will find out how to properly clean mould off bathroom sealant.

Health risks and effects of mould

Mould can trigger a number of health problems. For people with asthma and certain types of allergies, it can cause serious breathing issues that can quickly get them in the hospital, if they are exposed for a long enough period.

Mould disrupts lung function, making it harder to breathe, and it irritates the throat – causing coughing and shortness of breath. It weakens the immune system, causes allergies and black mould can even lead to asthma, especially in young children

Even for those who are healthy, mould exposure increases the risk of chest and lung infections, so you can never be careful enough when it comes to mould, especially the black one. The best course of action is to take care of it immediately and leave nothing to chance. 

Natural cleaning solution to get rid of mould on bathroom sealant

Cleaning with chemicals is not always the best option. They are not child and pet-friendly, can cause various health issues as well as allergic reactions. Using natural cleaners is better for your health, the environment and your wallet. Here are some of the best natural cleaners that will help you remove mould from your bathroom sealant.

Baking soda

Baking soda works great as a mould remover. Mix it with a bit of water until thick paste forms. Spread it onto the mouldy area and let it sit for a while. Then, using an old toothbrush, scrub the mould and rinse off with water.

If you wish to have a stronger solution, you can mix baking soda and vinegar.

Vinegar

White vinegar is an all-around cleaning agent and it’s also a fantastic mould remover. 

To clean the mould off the sealant, pour equal parts white vinegar and water in a spray bottle and apply the sealant thoroughly. After that, scrub it gently with an old toothbrush and finally rinse with water. 

Borax

To create a cleaning solution with this ingredient simply mix one cup of borax with three litters of hot water. Scrub the solution into the mouldy area and wipe away with a cloth.

How to get rid of mould from bathroom silicone sealant using bleach

Bleach is very effective in removing mould from most surfaces. However,  you should be very careful while using it, as it produces strong fumes that can harm you. Make sure your bathroom is well ventilated while using bleach and similar products. Put rubber gloves to protect your hands and cover your eyes from splashbacks. Also, make sure there are no kids and pets around. Here’s how to clean mould from bathroom sealant using bleach.

  • Pick up some household bleach of your choice and some cotton wool.
  • Pour the bleach on the sealant and place the cotton wool on top, so that it keeps the bleach in place.
  • Let it sit for a couple of hours.
  • After that, remove the wool and rinse off with water.
Bear in mind that bleach can cause tile and grout discolouration.

How to prevent mould in the bathroom

Mould in your bathroom is mostly caused by high moisture levels. To stop it from building up, you need to keep your bathroom as dry as possible. 

Use a vent when you use the shower and keep it on for at least 10-15 minutes after you’re done. If your vent is not working, make sure to fix it or buy a new one. Another great tip is to wipe the shower tiles and surfaces with a dry cloth after taking a shower. 

If you’ve tried everything but without any success, we recommend turning to a professional cleaner. They have the necessary experience and equipment to get rid of the mould in your bathroom sealant.

We’re sorry to hear that, Sally. You’re not alone, lots of people are struggling with mould. Usually treating with vinegar (what actually kills the mould) and after treating with bleach (to lighten the mould spots) does the job. If the problem is reoccuring, the best treatment is prevention. For example, to prevent mould in the bathroom or other humid rooms, it’s worth investing in a really powerful extractor fan.

If you’d like, you can share your specific problem and we’ll do the best to find a solution for you.
