Mould loves to grow and spread around grouted areas in bathrooms given the damp and moisture-rich environment.
Grout’s porous nature means it readily absorbs water, steam, or soapy remnants, creating perfect conditions for mould.
While bleach and white vinegar are two common go-to items for cleaning mould stains, their harshness and potential to damage tiles have people seeking alternatives.
Andrew Saladino from Kitchen Cabinet Kings suggests a gentler yet effective method using household items.
He explained: “Baking soda is an alkaline substance. Mould doesn’t like that. Mould prefers to grow in slightly acidic environments instead. Because of this, you can use baking soda to kill mould.”
The beauty of baking soda lies in its high absorbency, which not only kills mould spores but also prevents them from scattering.
For an even more potent homemade cleaner, Andrew recommends adding hydrogen peroxide, a natural disinfectant with anti-fungal qualities that eradicates mould and other bacteria lurking in the grout.
Andrew said: “Hydrogen peroxide is also a good way to kill mould. You can apply it directly to mouldy tile grout and let it sit then rinse.”
Firstly, ensure you’re dressed appropriately when tackling mould, as it can pose a health risk. Put on rubber gloves, a long-sleeved top, and if available, a mask.
Next, combine the baking soda or borax with a touch of warm water until it forms a paste.
Apply this paste to the mouldy grout and leave it untouched for at least 10 to 15 minutes.
Then, pour the hydrogen peroxide straight onto the paste, which will instantly start to foam.
Andrew said: “Watch as it bubbles and fizzes. This will loosen more mould spores in the grout and allow you to remove the mould more easily.”
Use an old toothbrush that’s no longer needed and a clean cloth to wipe away the cleaning solution. Be mindful not to use a scrubbing brush as you could risk damaging your tiles.
Andrew added: “Remember, baking soda is abrasive. You should avoid scrubbing your tiles directly with a baking soda mixture. If you’re going to use this cleaning agent, use a thin brush or toothbrush.”
After rinsing the tiles with clean water, your grout should be gleaming clean and entirely free from mould.
