How to clean and lighten grout using a scrubber

Last updated: October 27, 2026 8:00:00 AM

You can easily brighten dingy floors by scrubbing the recessed lines between your tiles. This step-by-step method helps you lift stubborn stains and restore a fresh look to your surfaces.

To clean and lighten grout using a scrubber, start by mixing a basic paste of water and baking soda, apply it along the lines, and scrub the surface firmly in circular motions. Finish the process by rinsing away the loosened residue with clean water and wiping the area completely dry with a towel.

Grout is porous, meaning it readily absorbs dirt, spills, foot traffic, and natural oils over time. Because it sits lower than the surrounding tile surface, it naturally becomes a collection point for debris. While routine sweeping and mopping keep the top layer of tile looking presentable, they often push dirty water directly into the recessed grout lines. Over the months and years, this trapped grime darkens, making even the cleanest floors and walls look dingy. Refreshing these lines requires a mechanical approach—using a scrubbing tool combined with safe, effective cleaning agents to lift the stubborn embedded discoloration.

Gather Your Simple Supplies

Before beginning, collect the necessary items to handle the task efficiently without damaging the surrounding tile. You will need a stiff-bristled scrubbing tool, which can be a handheld brush with firm bristles or a specialized tool designed specifically for narrow crevices. Avoid metal brushes, as they can scratch delicate tiles and tear up the grout surface.

Prepare a bucket of warm water, clean rags or microfiber towels, and a pair of rubber gloves to protect your skin. For the cleaning solution, plain baking soda is an effective, non-abrasive option that helps lift stains. Having a spray bottle filled with white vinegar or plain water is also useful for rinsing and activating paste solutions.

Sweep and Vacuum the Surface

Start by clearing away all loose dirt, dust, and hair from the floor or wall. Use a broom with soft bristles to sweep every corner and crevice, or run a vacuum cleaner equipped with a bare floor setting over the area. If you are cleaning a shower wall or a kitchen backsplash, use a dry microfiber cloth or a soft brush to sweep away loose particles.

Pay special attention to the corners where walls meet floors, as dust tends to accumulate heavily in these hidden spots. Once the entire area is free of loose dirt, take a damp cloth or mop to quickly wipe down the tiles so you can clearly see the discolored areas that need the most attention.

Apply the Cleansing Paste

Create a thick paste by mixing baking soda with enough water to form a spreadable consistency, similar to frosting. Spoon or smear this mixture directly along the discolored lines, ensuring every dark stretch is generously covered. For exceptionally stubborn grease or heavy foot traffic stains, you can substitute hydrogen peroxide for water in the paste mixture to boost its whitening capabilities.

Allow the paste to sit undisturbed for a period of time, typically ten to fifteen minutes. This resting phase gives the mixture time to penetrate the porous surface of the mortar and loosen the bonds holding the trapped grime in place. If the paste begins to dry out too quickly in a warm room, lightly mist it with water from a spray bottle to keep it active.

Scrub the Lines Firmly

Take your scrubbing tool and place the bristles directly into the treated lines. Apply steady downward pressure and move the tool in short, firm circular motions. The friction created by the bristles, combined with the gentle abrasive action of the baking soda paste, will begin to break down the embedded dirt and lift it out of the pores.

Do not press so hard that you flatten or snap the bristles of your tool, but use enough force to feel the friction working against the surface. If a particular spot remains dark, apply a little more paste and give it a second round of scrubbing.

Rinse and Wipe Away Residue

Once you have finished scrubbing a section, it is vital to remove the dirty slurry before it settles back into the porous gaps.

Change your rinse water frequently as it becomes cloudy. Continue wiping and rinsing until the water runs completely clear and no gritty residue remains on the tiles or the mortar. If any white baking soda powder dries on the surface, it will leave a hazy film that dulls the finish of the tile, so be thorough during this rinse phase.

Dry and Inspect the Results

Take a dry towel and thoroughly dry the entire area, pressing firmly into the lines to absorb lingering moisture. Inspect the results under good lighting once the surface is completely dry. Keep in mind that wet grout always appears darker than dry grout, so waiting for it to dry entirely is the only way to accurately judge the color improvement.

If certain areas still show signs of discoloration, you may repeat the process on those specific stubborn spots.
