Remove everything from the bathroom floor to give yourself an unobstructed space to work. Pick up bath mats, trash cans, scale models, and any storage bins sitting on the tiles. Sweep the floor thoroughly with a soft-bristled broom, making sure to pull dirt and hair out from the corners and baseboards. Follow the sweeping with a dry microfiber dust mop to capture fine grit that a broom might leave behind. If left on the floor, this gritty dust can scratch the tile glaze or turn into a muddy paste when you add liquids.

Next, inspect the grout lines for missing chunks or deep cracks. If you find areas where the cement has crumbled away, avoid scrubbing those spots aggressively, as water and cleaning solutions can seep into the subfloor beneath. Close the bathroom door if you want to contain any scents, and open a window or turn on the exhaust fan to ensure proper ventilation while you work. Tape off wooden baseboards or metal floor vents with painter's tape if you are worried about splashes or runoff reaching vulnerable surfaces.

Mix and Apply the Cleaning Paste

Combine ordinary baking soda with warm water in a small bucket or bowl until it forms a thick, spreadable paste. The consistency should resemble frosting so that it clings to horizontal and vertical surfaces without immediately running off onto the tile face. If your bathroom floor has stubborn discoloration, you can substitute hydrogen peroxide for the water to add mild lifting properties, though plain water is usually sufficient for routine maintenance.

Scoop small amounts of the paste onto your fingertips or use an old spoon to dollop it directly along the grout lines. Work in manageable sections, covering a square yard or two at a time so the paste does not dry out before you reach it. Ensure every inch of the visible grout is covered with a thick layer of the mixture. Let the application sit undisturbed for about ten to fifteen minutes. This dwell time allows the base to soften grease, oils, and soap residue trapped within the porous material, making the physical removal step much easier.

Work the Scrubber Along the Joints

Take your hand-held or long-handled scrubber and position the bristles directly over the paste-covered grout lines. Apply firm, steady downward pressure and move the tool back and forth in short, controlled strokes. If you are using a mechanical scrubber with a rotating head, let the weight of the device do most of the work while you guide it slowly along the path of the joints. Keep the bristles centered in the trench between the tiles to ensure the sides of the tiles do not take the brunt of the friction.

For stubborn spots where foot traffic has ground dark stains deep into the cement, pause the back-and-forth motion and make small circular passes with the bristles. You should notice the white paste turning a grayish-brown color as it lifts the accumulated dirt and grime out of the porous surface. Avoid pressing down with excessive force if the bristles are extremely stiff, as this can wear down the edges of the grout or scratch glazed tile finishes. Maintain a steady rhythm, working your way systematically from the farthest corner of the bathroom toward the doorway so you do not trap yourself in a wet corner.

Take a dry, clean towel and hand-dry sections of the floor, or use a dry microfiber mop to absorb the remaining moisture. Drying the floor immediately prevents suspended dirt from settling back into the wet pores of the freshly cleaned grout as the water evaporates.

Once the floor is completely dry, crouch down and inspect your work under good lighting. Look closely at the grout lines to see if any dark patches remain. If you spot areas that still look discolored, spot-treat those specific sections by repeating the paste application, dwell time, and scrubbing process just for those trouble spots.

When you are satisfied with the results, dispose of any leftover cleaning paste, empty your buckets, and rinse your scrubber thoroughly under running water to remove trapped grit and residue. Stand the scrubber up or hang it by its handle to let the bristles dry completely in a well-ventilated area before storing it away. Return your bath mats, scale, and other items to the floor only after the entire room is completely dry to prevent trapping moisture against the surface.
