Nothing is as regrettable as a beautiful new floor tile or wall being marred by dirty, discolored grout. Grout is naturally porous, causing it to absorb dirt, grease, and limescale faster than the tiles themselves. Fortunately, with the right approach, you can clean your grout and make it shine like new again.
In this guide, we'll explain everything about cleaning grout: from tips on the best products to a handy step-by-step plan.
Why regular grout cleaning is important
Grout is the "glue" of your interior, but also the place where bacteria and fungi like to settle, especially in the bathroom. By regularly cleaning your grout, you prevent dirt from penetrating deep into the material and causing discoloration. This not only extends the lifespan of your tiling but also ensures a healthy and fresh environment.
Cleaning Grout: What you need
Before you start, it's helpful to gather the right materials. You don't need to immediately resort to aggressive products; you probably already have many of them at home:
- Grout cleaner or a powerful degreaser
- Cleaning vinegar (only for ceramics, not for natural stone)
-
A grout brush or an old toothbrush
- Bucket of warm water and a clean cloth or mop
- Optional: A professional grout cleaner for stubborn dirt.
Steps to gleaming grout
To achieve the best results, we have prepared a step-by-step plan for you:
- Make a cleaning paste: Mix baking soda with a small amount of water until a thick paste forms. Don't have this at home? Then use warm water with a good splash of degreaser.
- Apply the cleaning paste: Generously spread the paste on the grout with a brush or cloth. It's okay if some gets on the tiles.
- Let it soak: Let the mixture sit for about 15 to 20 minutes. This gives the product time to loosen the dirt from the pores of the grout.
- Scrub: Take the grout brush and thoroughly scrub the grout clean. Use circular motions to loosen all the dirt.
- Mop or wipe: Prepare a mild solution of all-purpose cleaner and hot water. Mop the floor or wipe down the wall to remove baking soda residue and loosened dirt.
- Rinse: Always rinse with clean water. This prevents a dull film from being left behind on your wall tiles.
Stubborn dirt: Limescale and mold
Sometimes a standard soap solution isn't enough. In specific areas, you have to deal with stubborn enemies:
Limescale in the grout (brown/yellow stains)
In the bathroom, limescale is often the culprit. This gives the grout a yellowish or brownish sheen. Use professional descaler or cleaning vinegar. Note: Always test this first in an inconspicuous spot, as acids can affect some grouts and natural stone.
Mold (Black spots)
Black spots on your grout often indicate mold due to high humidity. Use a special mold remover for this. Spray it on the grout, let it work, and rinse it thoroughly. Afterward, ensure better ventilation to prevent recurrence.
Prevention is better than cure: 3 golden tips
- Use a grout protector: After thoroughly cleaning the grout, you can apply an impregnating agent. This creates an invisible, water and grease-repellent layer over the grout, preventing dirt from penetrating.
- Ventilate your bathroom: After showering, open the window or let the mechanical ventilation run for an extra half an hour. The drier the room, the less chance of mold.
- Clean mop water: Regularly change your cleaning solution to prevent dirty water from being drawn directly into the grout of your new floor tiles.
