To clean flour grout using baking soda and vinegar, apply a thick paste of baking soda and water to the lines, scrub gently with a brush, and then spray vinegar over the fizzing mixture before wiping the area clean. This simple kitchen pantry method breaks down stubborn grease, dark stains, and grime that settles deep into the porous mortar between tiles without relying on harsh chemical solvents or expensive specialized cleaners.

While the term "flour grout" usually describes traditional lime-based or cement-based grout that has taken on a dull, powdery, or chalky appearance from years of foot traffic and household dust, the technique remains identical for standard floor mortar. Over time, these recessed lines absorb cooking oils, tracked-in dirt, and moisture, turning a bright white or neutral shade into a dingy gray or brown. Using basic household staples allows you to lift the discoloration safely while preserving the structural integrity of the mortar lines.

Gather your supplies before beginning the task. You will need plain baking soda, white vinegar poured into a clean spray bottle, a soft-to-medium bristled scrub brush, a bucket of warm water, and several clean microfiber cloths or old cotton towels. Avoid using steel wool or metal-bristled brushes, as these aggressive tools can scratch the surrounding tile glaze and gouge the soft mortar, leaving behind permanent damage that traps even more dirt in the future.

Ensure every discolored section is covered with a thick, opaque layer of the paste. Do not worry about getting some paste on the adjacent tiles, as the baking soda will not harm standard ceramic or porcelain surfaces and will actually help clean any greasy film on the tile edges.

Scrub the Grout Lines Gently

Allow the baking soda paste to sit on the grout for about ten minutes to loosen surface oils and soften embedded grime. Take your brush and begin scrubbing the lines using small, circular motions. The physical friction of the bristles combined with the mildly abrasive texture of the baking soda will dislodge the trapped dirt without wearing away the mortar.

Spray the Vinegar to Activate Fizzing

Once you have scrubbed the grout lines, take your spray bottle filled with white vinegar and mist the paste generously. The moment the acidic vinegar contacts the alkaline baking soda, a chemical reaction will occur, producing a noticeable fizzing and bubbling sound.

This effervescence is entirely normal and helpful, as the rising bubbles help lift loosened dirt particles and organic residue out from the microscopic pores of the grout. Let the mixture fizz and rest for another five minutes. Do not let the solution dry out completely, as a dried crust is much harder to rinse away later. If the room is particularly warm and the mixture begins to dry too quickly, give it another light mist of vinegar or warm water to keep it workable.

Wipe Away the Residue

Take a clean microfiber cloth or cotton towel, dampen it with warm water, and wring it out until it is merely damp rather than dripping wet. Begin wiping away the slurry of baking soda, vinegar, and loosened dirt from the tiles and grout lines.

You will likely need to rinse your cloth frequently in the bucket of warm water to avoid simply spreading the muddy residue back across the floor.
