    Depending on the scale and location of the mould, you may be able to remove it yourself. The NHS advises that you only remove mould if its caused by condensation and covers an area less than one metre squared.

    If this is not the case, you will need to call a specialist, such as a mould remediation and removal company or damp repair company.

    Before you look at removing any mould from your home, it is important to identify the source. Common areas where mould forms include the walls, ceiling, on bathroom tiles, grout, basins and bathtubs, drains and behind shower tiles – which can result in large repair costs if the damage is extensive.

    How To Prevent Mold In Grout

    The drier the tiles, the smaller the chance of mold developing in the grout lines.

    As you certainly know, prevention is the best cure. And indeed, why spend so much time and effort cleaning mold from grout, when you can simply prevent it from appearing altogether? All you need to do in order to keep mold under control is to deprive it of the main prerequisite for its growth moisture. Just keep the tiles dry and youll never have to worry about the harmful microorganisms.

    But how can you remove moisture from a room that is designed to be wet such as the bathroom, for example? It sounds absurd.

    You cant, of course, but you can reduce the dampness there is a big difference between getting wet and staying permanently wet.

    Here are some simple, yet highly efficient measures you can take to lower the humidity in your bathroom, kitchen, and other wet areas of your home and prevent mold growth:

    1. Keep doors and windows open for as long as possible to ensure proper air flow within the home:

    • Let the bathroom window stay open for at least 15 minutes after you turn the shower off, so that excess moisture can move out of the room rather than condense on the walls and tiles;
    • Leave the shower door open when the shower is not in use;
    • Keep the kitchen windows open while cooking to allow the steam to escape;
    • Ventilate the laundry room, basement, and attic as often as possible.

    8. Fix leaky faucets and showerheads to remove the source of excess moisture in your bathroom and kitchen;

    How To Remove Mold From Grout Naturally

    Many sources advise using baking soda and vinegar as a natural agent to remove mold from the shower grout. I have decided to test this advice out, and the results were unexpected.

    Optimum pH

    The primary reason why baking soda and vinegar works well in combating mold lies in their pH. The mold usually grows in pH 3 7 . If you have black mold in shower grout, the chances are that you are dealing with the Stachybotrys Chartarum. Its optimal pH for growth is 5.6-6.0 . Because of that, to get rid of the mold and keep it away, it helps to use ingredients that change the pH of the infested area, creating a hostile environment for the mold.


    I know that using baking soda and vinegar is a widely spread tip; however, I have seen various alternatives of how to use those ingredients, e.g.:

    Baking Soda + Water Baking Soda + 3% Hydrogen Peroxide Baking Soda + White Vinegar Baking Soda + White Vinegar + 3% Hydrogen Peroxide Vinegar

    But what is the best option? I have tested all the combinations mentioned above, leaving them to sit in the grout for about 20-30 minutes. First, I have started with 30 minutes, but then I have shortened it to 20 minutes, and the results seemed similar. The findings were quite surprising.
