How To Clean Black Mold From Bathroom Sealant

Health Risk Of Black Mold


Mold is gross to look at but what is the real risk? It turns out that mildew and mold growth in the bathroom does not pose a serious health crisis unless the mold spores begin to spreadthrough the rest of the house.

Some types of mold become a danger when allowed to spread on surfaces with cellulose, which is found in wood and wood-derived materials such as paper and fiberboard.

If the mold penetrates the walls, floorboards, and rafters, the toxic mold may develop.

In bathrooms, the mold is more likely to cause minor respiratory issues in some individuals. Potential symptoms include:

  • Itchy eyes
  • Rashes
  • Skin irritation

During a severe reaction, you may also find it difficult to take deep breaths. If you detect these signs, remove mold and consider having your property inspected for the spread of moldthrough other areas.

While mold is rarely a danger, remove it before it has the chance to spread. It can easily travel through air ducts and settle in rooms throughout the house.

How To Remove Mould From Smooth Surfaces

This should be a fairly easy win. Spray your cleaner onto the surface and wipe it away with a clean cloth. If you have a lot of mould to clean, you may need several cloths. Forget trying to rinse them, just change them and then either throw them away or hot-wash them before further use. If you have really heavy-duty mould then you may want to use a scrubbing brush. In this case, rinse it with the hottest water you can stand.

How To Keep Black Mold In Your Bathroom Away

Once youve gotten rid of the mold, youve got to keep it away with regular maintenance. Regularly spraying vinegar on bathroom surfaces and letting it air dry kills mold spores and prevents growth. Make sure theres proper ventilation in the bathroom and install an exhaust fan if you dont have one. If you can, wipe down the shower with a cloth or squeegee after showering. Clean the bathroom weekly using your preferred cleaner and use an antifungal cleaner once a month.

How To Get Mould Out Of Shower Curtains

A shower curtain offers privacy to your bathroom but also acts as a means of catching condensation. Mould can develop at the bottom where liquid collects, or over the rest of the shower curtain if moisture is left to settle for too long.

Remember to regularly clean it in a washing machine or in a large bucket. You can soak the curtain in a mixture of warm water, bleach and washing detergent. A non-toxic option is adding baking soda and vinegar into a solution of washing liquid and water.

You may need to do this more than once, as plastic blocks water, or scrub the curtain with a brush. If that doesnt work, you may need to replace it.

Always remember to dry the shower curtain thoroughly once youve cleaned it and removed the mould.

There are also mould remover liquids available to tackle surfaces that include showerheads, drains and taps.

How To Remove Mould From Drains And Walls

Often, the first place that mould inevitably appears around is the drain. From there it often spreads to the shower floor and walls. While this does appear really unsightly, it can be treated rather efficiently. The first step is to mix up your treatment solution whether that be a mixture of bleach and water or, the more effective mixture of vinegar and water.

Clean Mold Off Silicone Caulking

How to Clean Black Mildew Mold Mould from Shower Silicone Mastic Sealant 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 call a local contractor 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.

    What Are The Effects Of Black Mold Exposure

    How To Remove Mold Mould From Silicone Sealant In Bathroom Shower

    Black mold is a fungus that is dark green or black and has a mildew or musty odor. It grows in areas rich in cellulose like wood, fiberboard, paper, and gypsum board. Mold grows in warm and damp places like laundry rooms, shower cubicles, and bathrooms.

    It will hide in any crevice and quickly take over your bathroom or shower. Getting rid of it, you will need a strategy, special weapons, and a strong determination to win. Part of your strategy is to know your enemy, know how it works and know its weakness.

    Molds release harmful toxins into the air, and we inhale these toxins. It is very harmful to children, people with respiratory conditions, and people who have a weakened immune system. Black molds have mycotoxicosis that causes black mold poisoning. If you have Black Mold in your home and someone is sickly, have them tested for Black Mold poisoning.

    Children who inhale Black Mold often get asthma.

    Go One Step Further With Dehumidifying

    If your extractor fan and windows arent removing enough condensation, you can also invest in a dehumidifier. There are two main types of free-standing dehumidifiers: electric appliances and absorbent dehumidifiers.

    Electrical appliances will need to be plugged in and you can choose to run them while you take a bath or shower. Absorbent dehumidifiers dont need an electricity supply.

    They work by using absorbent materials to remove humidity from the air and are effectively working all the time.

    Other Ways To Get Rid Of Black Mold In Shower

    In cases when you dont have all the ingredients and items above, you can use the alternatives listed below:

  • Using white vinegar on its own. You dont need to dilute or even rinse it off afterward. For this method, the vinegar should be left to sit on the mold for at least 30 minutes before being rinsed off.
  • You can also use a diluted solution of Borax. You should mix 204 grams of borax powder in 3.8 liters of water. Simply spray it on the affected areas then leave it as it doesnt require rinsing. Leaving it on the surface of the silicone prevents future mold growth.
  • Using baking soda paste and hydrogen peroxide. Make a baking soda paste and apply it to the affected areas then pour hydrogen peroxide on it. As the paste fizzes, scrub it off then rise it with water.
  • Using diluted bleach. Diluting one part bleach to 10 parts water gives you a solution you can spray and leave on the affected areas of your silicone. You can either spray the bleach on the mold or put cotton balls soaked in bleach on the affected areas.
  • If the above solutions dont work straight away, it could be that the mold has affected the areas underneath the silicone. This may force you to replace the silicone with a new sealing. Given that silicone is not used for covering very large areas and is easy to remove, the task can take you under an hour to complete.

    How To Clean Mildew From Silicone Seals In The Shower

    Q: Id like to know how to clean the mildew from the silicone seals in my frameless shower. The shower never looks clean with that blackened silicone. Or would I be better off removing the silicone and settling for a little water leaking out?


    A: Chlorine bleach removes mildew stains. When the stains are on silicone sealant, one trick is to place wads of toilet tissue against the stained areas and then dampen them with bleach. An old toothbrush works well as a tool for transferring the bleach. Leave the dampened paper in place for half an hour or so, then collect the wads and rinse the shower area.

    That said, the picture you sent shows significant gaps in the sealant. You might want to remove and replace it. Do not just leave the gaps unsealed, however. The biggest challenge is removing all of the old caulk, given that silicone sticks so well. Use a razor scraper with single-edge razors to cut and peel away the silicone and to scrape off any remnants. It helps to use caulk remover, such as 3M Indoor/Outdoor Caulk Remover . Clean up any residue, using rubbing alcohol to remove residual soap scum.

    Immediately smooth the sealant with a damp index finger one pass only. If it doesnt look perfect and you try to tidy it up by going over it a second time, you will almost certainly make it messier. Remove the tape immediately, or there will be a ridge a place for mildew to grow along the edges of the caulk.
