How to remove mould from grout

With Christmas and the holiday season fast approaching, so are those long-awaited guests and there’s nothing nicer than having a beautifully clean home ready for them. If you’re struggling to remove mould from the grout in your bathroom, follow this simple advice.

Why remove mould from grout

Moulds have existed for millions of years, according to the Centers for Disease Control and Prevention (CDC) – but that fact doesn’t make mold safe to have around. A good rule of thumb is if you see or smell mold, remove it.

As a fungus, mould thrives in moist spaces and can grow both inside and outside. Our teams across the UK constantly see mould in bathrooms, kitchens, laundry rooms, basements and even garages so we have the tips you need to get rid of it safely and effectively.

Why mould develops on grout

One of the most common places to find mould is between tiles, because the porous nature of grout is highly susceptible to microscopic growth. Whether part of a kitchen backsplash or bathroom detail, tiles usually see a ton of moisture. Rarely do we take the time to dry tiles or the grout between them completely after we cook or wash. If a damp room has inadequate ventilation and you don’t run a fan or dehumidifier, it quickly becomes the right environment for mould. Removing mould from the grout between tiles can be tedious, but it’s well worth it to avoid mould-related illnesses.

How to remove mould from grout

Fortunately, there are several cleaning agents that work to remove mold froum the grout between tiles. When cleaning the grout between tiles, first check to make sure the cleaning agent you use won’t cause any damage to that specific kind of tile. Some tiles should not come into contact with bleach or abrasive agents like baking soda.

Safety first. Always work in a well-ventilated space with an open window or operational fan. Wear non-porous gloves to protect your skin, and don’t forget safety glasses to protect your eyes from splash-back while cleaning.

Chlorine bleach. Regular chlorine bleach works well to remove mould from white grout. Avoid bleach if you have colored grout, since it can cause fading, and never mix bleach with other cleaners. Wear a mask along with your other protective gear to keep from inhaling the bleach. Work in small sections and scrub the bleach directly onto the mouldy grout using a stiff bristle toothbrush. Let the bleach sit for at least 30 minutes (keep the exhaust fan running), then rinse with warm water. Repeat as needed.

Distilled white vinegar. Vinegar is a great, natural cleaning agent and generally won’t cause grout discoloration or deterioration. Using a spray bottle, saturate the mouldy area with white vinegar. Let it sit for 30 minutes and then scrub with a bristle brush, being careful not to chip away at the grout itself. Spray again and let sit for another 30 minutes. Rinse with warm water, and repeat if necessary.

Baking soda paste. Baking soda is a stellar lifting agent. To make a paste that you can spread over mould to lift it, stir together 1/2 cup of baking soda and several teaspoons of water. Adjust the combination until you have an easily spreadable consistency. Apply the baking soda paste directly over the mouldy grout, let sit for 10 minutes, then scrub the mould away with a bristle brush. Rinse with water, and repeat as needed.

Baking soda plus hydrogen peroxide. Apply a thick baking soda paste to the area affected by muold. Spray or carefully pour hydrogen peroxide over the baking soda paste so it begins to fizz, which will help loosen the mould further. Scrub the fizzing paste using a stiff bristle brush, then rinse the paste and mould away with water. Repeat as needed.

Tip: If there’s mould on the sealant that seals around your bath, taps, sink or toilet, the safest thing to do is remove the sealant. Sterilize the area with bleach or distilled white vinegar and dry it thoroughly before replacing the sealant. Opt for a mildew-resistant sealant to inhibit the growth of future mould.

Some mould problems can’t be tackled with home remedies or commercial cleaning produts found at your local supermarket. If you’re facing stubborn grout mould or too much mould to handle alone, call the pros at Merry Maids for complete mould removal from any area of your home.
