How to Remove Ugly Black Mould from Shower Silicone

EC3 Mold Solution is a natural compound consisting of citrus seed extract, plant oils, and distilled water. It works on almost every surface, including fabrics, tiles, wood, concrete, and even soft furnishings.

Spray an even coating over your sealant and leave it to stand for 10 minutes. Then rinse it off with water and dry thoroughly. Now reapply a new layer to the caulk and leave it to dry naturally.

You can spray this solution as many times as you like for preventative measures.

Mixing up a solution of white vinegar and water in a spray bottle and applying it every week will also reduce the chances of mold growth.

You could even spray it every day. If you dont like the smell of vinegar, try adding in a few drops of essential oils, like tea tree oil, to improve the fragrance.

Hydrogen Peroxide And Baking Soda


  • EC3 mold solution spray


First, you should apply a thick layer paste made of baking soda and a little water over the mold. Then, pour 3% hydrogen peroxide over it. You will see that it begins to fizz, which means that destroying the old and stubborn mold starts.

What Causes Black Mold

How to Get Rid of Black Mold in Your Shower Caulking

Mold thrives in hot, humid, and damp conditions. It also loves spaces with low light because sunlight dries the surface, removing the food that mold needs to grow. Every time you shower, moisture enters the atmosphere and circulates.

Mold is highly resilient and can survive in extreme conditions, so getting rid of it once it has found a home is tricky. It also has a habit of swiftly returning once you think you have eliminated the problem.

Mold loves cellulose above all other food sources, although it also likes other organic matter. Wood, drywall, grout, and caulk are all common feeding grounds for black mold. Caulk helps to repel water, so it sits on the surface and leaves a feast for mold.

Also, if you leave the bathroom with dampness in the air, mold will start forming in a few weeks. Plus, wet towels and clothes help trap humidity and moisture, while leaks and humidifiers play their part in allowing it to grow.

Q: Does Bleach Really Work To Kill Mold

A: You may have heard that bleach is ineffectual for dealing with mold. Actually, it can be ineffective on porous surfaces. But in the bathroom, you are dealing with caulk, which is non-permeable, and the non-porous surfaces in your shower. So, using bleach and cotton balls should work just fine.

But if you do not want to use this method or if it is not getting the job done for whatever reason, there are some other ideas you can try.

Important Tips On How You Can Prevent Growth Of Mold

Molds are not something that should be taken lightly. The toxic effect in them is harmful to your health. It is said that prevention is better than cure and thats why you should be intentional about preventing black mold or any other type of mold from growing in your home.

Are you wondering how you can go about that? Here are tips that will ensure your caulk, bathroom, or other areas are free from mold.

  • Use Household Fan

Fans are common equipment in most homes and they play a great role in ensuring your house is free from moisture or smoke.

A good example is when you are boiling some water and the water vapor spreads to your kitchen walls. If you dont do something the vapor will not only cause the growth of mold but will also increase humidity. However, you can prevent that from happening with a fan.

  • Keep The Windows Open

When the vapor is held in the air, it will settle on your doors or windows and walls. This will increase the chances of mold growth in your home. However, you can prevent this by keeping the windows open to get rid of the vapor quickly.

This will ensure there is enough air circulation and also the regulation of humidity in the house. In case its winter time and you dont want to expose your family to cold, standing or ceiling fans might come in handy in curbing the vapor and humidity.

  • Check Outdoor Drainage

This is another great tip when it comes to the prevention of mold. If your home is located along a water path, you might have problems with mold.

Clean Mold Off Silicone Caulking

A second option is to clean the mold off of the caulking. This is only recommended if the mold is very limited in size and growth. I would say anything that is less than five or six inches in length can be cleaned, then monitored to see if the mold comes back. If it does come back I would remove the silicone caulking and replace it with fresh caulking.

When you replace the caulking you should investigate the type of caulking you use. There are some new brands of caulking that are mold resistant or are treated with a chemical that kills mold. As always if you are not comfortable doing the job yourself that has experience in removal and or working with mold. They will often know how to control the issue, remediate it and fix the ongoing issue that caused the mold.

    Create A Vinegar Solution

    There are a few solutions you can use to remove mold from your bathroom, but its best to start with the ones that are the safest. Vinegar is a natural, non-toxic mold killer.

    Its powerful enough to remove mold and mildew from a wide variety of surfaces, including shower caulk. For starters, you need a clean, empty spray bottle and some vinegar.

    You can pour the vinegar into the bottle without diluting it. If you dont water it down, it will deliver a better result. Spray the mold-covered areas with vinegar.

    This solution doesnt smell that nice, but the odor should clear within 2 hours. If your mold problem is a bit more serious, dont rinse the vinegar away after youre done.

    But, if your mold problem isnt so big, and you dont want your shower to have an unpleasant scent, you can mix the vinegar with a bit of water.

    You wont compromise the antifungal power of vinegar by much if you add a bit of water, but you will reduce the pungent smell. This is also a better option for those who have a larger area to clean as theyll have more liquid to work with.

    Q: What Are Some Alternatives To Bleach To Kill Mold

    A: If you are not keen on using bleach, there are a number of other solutions you can consider for getting rid of mold.

    One method that can work well is to combine water and hydrogen peroxide in equal parts. You can use a spray bottle to dispense it. You will need to wait for a little bit while the hydrogen peroxide goes to work, and then you can rinse it off.

    Another option is to combine water and baking soda. You can try adding just a little baking soda to a spray bottle with water, then spray, wait, and wipe it down. Alternately, you can mix in more baking soda to form a thick paste, and scrub with a toothbrush.

    Yet another idea is to use vinegar. You do not need to dilute the vinegar with water. You can just pour it right into a spray bottle. Spray the vinegar on the mold, and then wait. After the vinegar has had some time to work, you can rinse it off.

    If you want to enhance your vinegar, you can add a bit of tea tree oil to your spray bottle. Spray it as usual, wait, and then rinse. With all of these methods, you can scrub if you need to.

    First Things First: Where Is The Mold Growing

    If mold is growing on top of your caulking or grout, consider yourself lucky. Why? Because mold can actually form inside or under grout or caulk. The reason this can happen is because over time, your caulking may crack. All it takes is a tiny fissure for mold to get underneath.

    To figure out what you are dealing with, soak a few cotton balls in bleach, and press them onto the affected area. If you see the mold go away right away, it is probably superficial.

    But if 30 or 40 seconds go by and you can still see some mold, then it is inside the caulk. That is bad news, but you can still stop mold, even when it penetrates your caulk.

    Instructions On How To Remove Mold On Caulking

    How to Remove Mold from Caulking in Shower

  • Fill a large bowl with water.
  • If using cotton balls, you can stretch out the cotton balls before dipping them in the bleach water to make it easier to attach to a wall.
  • Put on gloves and mask, open a window, and/or turn on the fan in the bathroom.
  • Add a small amount of bleach to the water. Mix.
  • Dip cotton balls into the bleach water.
  • Apply the cotton balls directly onto the caulking with mold on it in your shower or bathtub.
  • Continue adding cotton balls to moldy parts of the shower.

    Continue adding more cotton balls or cotton coils to all moldy caulk in your shower, including along window ledges, and up the walls. Because the cotton is so wet, it will stick vertically. However, start at the top and work your way down if bleaching moldy caulking vertically, as the liquid will seep out and make the cotton balls below it fall off. Its okay to keep the cotton fairly wet, but it doesnt have to be super wet and drenched, especially if doing vertical parts.

  • Leave the cotton there for about 2-4 hours or until mold is removed. Be sure to shut the bathroom door and keep the fan running as you wait.
  • Spot check an area to see if the mold on shower caulking is gone. If not, reapply and wait another hour.
  • If the spot check looks good, continue to remove the cotton balls or cotton coils from your bathtub caulking.

    Discard them into a trash bag. Always be sure to handle bleach with gloves on and a mask if you have one .
