How To Remove Black Mold From Shower Caulk

Tips and tricks to remove black mold from shower caulk when your bathroom mold seems to have gotten out of hand! Do you get black mold on your shower caulk? Mold is perhaps the most unpleasant ingredient in every shower cubicle, and the terrible reality is that mold spores are always there. When the spores are exposed to moisture and nourishment, they grow at an alarming rate.

Mold in the bathroom is a very common thing that a lot of us battle, and it’s so gross!

Mold LOVES warm and moist environments, so after a hot shower or bath, it’s essential to dry out your bathroom so that the mold has a harder time to get growing.

Unfortunately, a lot of us in older homes (like me!) don’t have a ventilation system in the bathroom, and that makes drying out the room a lot more difficult after taking a hot shower or bath.

If you have a window, make sure to keep it open so that the moisture dries up quickly. 

The only problem is, if you live in a winter wonderland, having the window open after a hot shower isn’t an option. 

Then you must take extra steps to make sure your tub dries up.

But those of us with kids and busy lives don’t take the time to make sure to dry out tubs, and the mold loves that!

I have an excellent daily shower spray that I make myself as well as some pretty awesome and easy to follow tips to clean the shower floor that you can follow to have a sparkly clean bathroom.

So how do you kill all that mold on your bathroom caulking?

A Note About Store Bought Bathroom Cleaners

Many store-bought bathroom cleaners had harmful chemicals in them which are not great for the health of your family. Making your own cleaners can reduce pollution to our waterways and the air, as well as minimize the impact on ozone depletion and climate change. There is no packaging either when you make your own cleaners, so that’s a plus

Causes Of Mold On Shower Caulk

Mold grows in places where there is a lot of moisture over an extended length of time. When the relative humidity level in the bathroom remains above 60% owing to inadequate ventilation, the spores found in any home will adhere to the shower caulking and proliferate. Mould feeds on wood, dirt, fabric, and paper. The majority of these chemicals are always present in the bathroom. Check out the EPA’s quick guide to mould and moisture in your home.

Tools You Need

How To Remove Black Mold From Shower Caulk

  1. Make sure you have your materials handy.
  2. Mix one part bleach with 10 parts water in a spray bottle.
  3. Spray the affected area with the bleach solution
  4. Wait for five to 15 minutes for the solution to do its job
  5. Gentle scrub away at the moldy area with the toothbrush or soft brush
  6. Rinse the area off, and wipe down with a clean and wet cloth.

This does the trick in my house, I hope it helps you too.

If the mildew does not go after wiping it away, it might be developing within the caulk. If the mold has pierced the caulk surface, the only solution is to remove the caulk and replace it with mold-resistant bathroom caulk.
If you start to feel light-headed throughout this procedure, step away from the area for a few minutes. To lessen the impact of cleaning, work in short amounts of time on large chores.

Alternative Methods I’ve Tried

These are also excellent methods, but in MY opinion, they didn’t work quite as well as the bleach solution. I PREFER to use no chemicals in the house, but sometimes, when it comes to mold and health, bleach is my go-to.

I’m well aware of the benefits of tea tree oil and its disinfecting properties, but come on…bleach is just much more durable, and so I trust it more in these situations.

However, if you don’t have bleach in your home, or you prefer to use natural products, there are some other things you can do to get the mold off.

Baking Soda Paste Solution

Just so you are aware, baking soda does NOT kill mold, but it can help remove any excess moisture from the caulking which helps prevent mold growth.

Create a paste with your baking soda and some water and apply it to the caulking.

Leave this paste on the caulking for 20 minutes or so.

After the 20 minutes has elapsed, go ahead and scrub away at the mold with a toothbrush or soft brush.

Hydrogen Peroxide

You can use straight hydrogen peroxide applied to the moldy caulking in your tub or shower.

Use a spray bottle to apply the peroxide and let it sit for 10 minutes or so before scrubbing it with a soft brush or toothbrush.

Make sure to dry the area when you are done!

Cleaning Supplies

Disinfecting The Area

After the mold has been removed, the shower’s remaining surfaces must be purged of mildew spores to avoid mold regrowth on shower caulking. Spraying the whole shower stall with the bleach mixture and then rinsing and drying the shower walls and fixtures is one of the most efficient ways to eliminate unseen mold spores. Perform this task at least 48 hours before leaving the residence. The spores that are there will perish after the rain has dried entirely. The mold prevention guidelines may then be put into action with a fully clean shower cubicle.

Caring For Your Shower Caulking

In order to keep the mold away from your shower caulking, the best thing to do is keep the moisture away. This means drying the tub or shower when you’ve finished washing up and cleaning your bathroom often.

Why Is It Important To Clean Your Bathroom Regularly?

You can prevent illness and infections when you keep your bathroom neat and clean on a regular basis. A bathroom that is not clean can cause difficulties in breathing. Mold and dust are very dangerous for individuals with already existing breathing issues such as asthma, pneumonia or COPD.

Microorganisms, Bacteria, Viruses, & Pathogens live up to a week on bathroom surfaces which means it’s very important to wipe down your counters, sinks and shower daily to prevent these from causing stomach problems and bacteria growth. The toilet, tub and sink are prime breeding grounds for all these bacteria and it’s so easy for people to contract salmonella, and intestinal distress if using a bathroom that is dirty and filled with bacteria.

Athletes foot, staph and strep can also be caused by breathing in bacteria in a dirty bathroom.

Ageing individuals have weaker immune systems, even if they are still healthy and active. Typical bacteria that live in bathrooms can affect the immune system seriously and easily for the older generation.

Removing Mold From Silicone Caulking

To eliminate mould from silicone caulking, remove the caulking and replace it with a fresh bead of caulking. Yes, this is more difficult than merely cleaning it, but it is the greatest method to ensure that it does not return.

Remove any sources of humidity that are causing the caulking to become wet (if possible).

Another approach is to remove the mould from the caulking. This is only suggested if the mold’s size and growth are relatively limited. Anything smaller than five or six inches in length can be cleansed and then watched to see whether the mould returns. If it reappears, I’d remove the silicone caulking and replace it with new caulking.
Some modern caulking products are mould resistant or have been treated with a chemical that kills mould. As usual, if you are unsure about performing the task yourself, contact a local contractor with experience in mould removal and/or working with mould. They will frequently be aware of how to control the problem, repair it, and resolve the underlying issue.

How do you get rid of mould between silicon sealers?
If you have silicone sealers surrounding your shower that have mould behind them, you must remove the silicone sealant and clean up/remove the mould. Finally, make sure the surface is clean and dry before reapplying the silicon sealant.

Keeping Your Bathroom Safe

Keeping your bathroom free of daily clutter helps keep the bacteria easier to control. Magazines and clutter next to the toilet area hold onto those gross toilet germs easily. Keep those items away from the toilet and be sure to always close the toilet lid when flushing to keep the bacteria from flying about the room.

Bathmats are also a breeding ground for bacteria so you should be washing your bathmat once a week.

Cleaning Sprays and deodorizer bottles should be rinsed regularly as well because the bottle of these substances can be just as germy as the surfaces you are cleaning with that bottle.

Also be sure to keep your cleaners tucked away safely out of reach of children. Baby proofing the bathroom when you have a little explorer is always a good idea.

How To Prevent Mold Growth On Shower Caulk

Mold cannot develop on surfaces in the home unless moisture is reduced and controlled. In very humid areas, adequate ventilation, as well as the use of air conditioning and dehumidifiers in the house, will reduce humidity levels to the desired range of 30-50 percent relative humidity. Outdoor air may be used to lower humidity in the home in arid areas. To minimize the return of mould, follow these guidelines after each use of the shower.

Vented bathroom fan – Building standards now demand one vented fan in each bathroom. This rule is waived for older properties until the bathroom is renovated. If a fan is installed, make sure the exhaust line is vented to the outside of the house rather than merely into the attic. After taking a shower, turn on the fan for an hour.

Remove damp towels — Instead of hanging towels in the same room, consider hanging them outdoors to dry or running them through the dryer. Wet towels are one of the primary sources of moisture in a mold-infested room and must be removed to reduce the relative humidity level.

Dry the shower stall – During and after a shower, water will cling to the shower tile and caulking. After drying the shower walls, remove the towel from the room.

Clean the shower walls once a week using a bleach-based cleanser to destroy any mould spores that may have accumulated in the shower since the last cleaning. To get the greatest results from the cleaner, carefully follow the instructions.

Humidity may be measured with a simple humidity metre, which can be obtained at a hardware shop. Place the metre near the shower and turn on the bathroom fan until the relative humidity level falls into the 30-50 percent range.

Using mould-resistant caulk in the shower will help you avoid it. In a bathroom, acrylic caulk is generally recommended. This guard against moisture, which is essential in a shower. The caulk is difficult for the fungus to penetrate, making it resistant. This will help keep fungus at bay, reducing the need to remove it in the future.

Tools

Follow these guidelines carefully to protect yourself from mildew spores that will contaminate the air throughout the mould treatment procedure.

  • To protect the skin from cleaning chemicals and mould spores, gloves and eye protection must be used.
  • To avoid inhaling mould spores that have become dislodged from the shower wall’s surface, use a mask that covers the nose and mouth.
  • Fill an adjustable spray bottle halfway with bleach and water.
  • Prepare a full bucket of hot, clear water for rinsing the surface with a clean sponge.
  • Wear a disposable paper overall for comprehensive mildew eradication that may be thrown after the operation is over.

Warnings

Mold can be dangerous to those who suffer from respiratory illnesses or allergies. Follow these precautions before attempting to remove black mould from shower caulking:

  • Wear all appropriate safety equipment.
  • Assess your own capacity to accomplish the assignment.
  • If the caulk must be changed, do not begin the procedure until you have adequate time to complete the replacement fully. If all of the caulk has not been replaced and allowed to cure fully, the shower will be inoperable.
  • Do not postpone! If you do not have the necessary skills to remove the mold, hire a trustworthy specialist to do it.
  • Black mold can cause serious health concerns.

How To Remove Black Mold From Shower Caulk

Put your prevention practices in place and avoid going through the trouble to remove black mold from shower caulk later on.
