Black mold growing on shower tiles in bathroomMost of us clean our homes on a regular basis. But, sometimes, it seems that no matter how hard you clean, there are still areas that can’t exactly be categorized as spotless. This is especially true for our bathrooms, isn’t it? That ugly green and black mould is often found in our shower tiles and even though we attempt to spray it with cleaner and wipe it away, it often will stubbornly remain. Sound like a problem, you have? If so, you’re not alone.

Mould requires dark, warm and moist environments in order to thrive. Ironically, the cleaner we get, the dirtier our bathrooms become. Quite obviously, showering introduces a lot of moisture to your bathroom. Especially when the shower is hot – and most are – both the water itself and the steam that arises from it is bound to keep the tiles warm and wet for quite some time after the shower is completed.

Not only is mould unsightly, but it is also known to present health hazards. Similar to dust, mould spores – when airborne – can enter our lungs. People who suffer from asthma and allergies are especially susceptible to the health risks associated with mould. So cleaning your bathroom is actually a much more important task than you may think. But how can it be cleaned in such a way that the mould actually disappears?

Here are four ways:

1. Create a baking soda and water solution. HowToRemoveBlackMold.com suggests that you place the baking soda solution in a spray bottle and use it to target all the areas where mould is present in your bathroom. Let the mixture sit for five to ten minutes, recommends the website. Then use an old toothbrush to scrub away the mould. After scouring the mould away, wipe away any excess solution and then rinse and repeat the process if necessary.

2. Use a white vinegar spray. If baking soda is unavailable, white vinegar may be a great alternative. On his website, David Suzuki writes that undiluted white vinegar can help to remove mould. He warns, however, that vinegar is a “strong acid” that can potentially etch your tiles or grout. “Use it only on the caulking and rinse off well,” he advises, “it’s always best to do a test patch.”

3. Try liquid oxygen bleach. Suzuki offers liquid oxygen bleach as another mould-removing suggestion. “It’s basically diluted hydrogen peroxide, found in the laundry aisle of your grocery store,” he informs, “Apply it with a spray bottle or follow the manufacturer’s instructions. Worst case scenario is if the mould has worked its way behind the caulking. In this case, you may have to re-caulk, and if you do, choose non-toxic, 100 per cent silicone.”

4. Be mindful of your humidity levels. One of the best ways to remove mould from your bathroom is to not let it develop to begin with. Suzuki reminds us that mould prevention is the best way to keep a safe and clean home. “Get a handle on the humidity of your bathroom,” he warns, “Make sure the fan is rated to fit the size of your bathroom and that it’s working properly.”

At DF Technical & Consulting Services Ltd., we strongly advocate for mould-free environments. As part of our mandate to have our clients live in homes that promote good health, we offer Mould Assessment Services that seek to locate all areas of the home where mould exists. You may be surprised to discover some of the places where mould may be hiding. For more information, please don’t hesitate to call us at 1-855-668-3131 or email info@dftechnical.ca.

    This is an informative article. I really appreciate your efforts for writing such an amazing post. Showering cause lot of moisture to a bathroom especially when the shower is hot because the steam which arises from it’s bound to keep the tiles warm and wet for sometime after the shower is completed. http://www.floodaz.com/how-to-remove-black-mold-without-killing-the-environment/

      Thank you for the information but I do have one question. Can the mold spread in to your air conditioning duct system ? If so you should have your air ducts cleaned often.

        Hello Anna
        Within your air conditioning duct many things can happen. They can be simply a pathway to move contaminants from one are to another or if the ducts are dirty they can be a food source for biological growth such as mould growing on debris inside ductwork. Ductwork should be cleaned to remove this source. Also Standing moisture in ductwork can also source for other contaminants such as Legionella.

          Your answer about the air duct cleaning is correct. It is recommended to clean the air ducts every two years to prevents mold growth.
