Apply the paste to the grout lines
Spoon or smear the baking soda paste directly along the discolored grout lines. You do not need to cover the entire tile surface unless the tiles themselves need cleaning, but focusing specifically on the recessed channels where mold, mildew, and body oils accumulate is key.
Use a gloved finger, an old spoon, or a small spatula to press the paste firmly into the grout joints. Ensure that every darkened or discolored section is completely covered by a visible layer of the mixture.
Let the mixture sit undisturbed for a specific duration to give the ingredients time to break down the organic bonds holding the dirt in place. Depending on how heavily soiled the grout is, leaving the paste in place for ten to twenty minutes is usually sufficient. During this time, you may notice the paste bubbling slightly as the ingredients react with the dirt and oils trapped in the porous grout. Do not let the paste dry out completely, as a dried-out crust is much harder to reactivate and scrub away later. If your bathroom is particularly warm or drafty and the paste starts drying too quickly, mist it lightly with plain water from a spray bottle to keep it workable.

Take your stiff-bristled brush and position the bristles directly inside the grout channel. Apply moderate downward pressure and move the brush back and forth in short, vigorous strokes along the length of the joint.
The physical action of the bristles flexing against the porous surface is what truly dislodges the embedded grime. Rather than just skimming across the top of the grout, angle the brush slightly so the outer rows of bristles push deep into the V-shaped or U-shaped recessed groove.

As you scrub, you will likely see the white paste turn gray or brown as it lifts the accumulated soap scum and dirt out of the grout pores. Pay extra attention to high-traffic areas, such as the floor directly in front of the shower entrance or the lower rows of wall tile where moisture lingers the longest. If you encounter stubborn spots that do not lighten immediately, add a tiny bit more dry baking soda directly onto the brush bristles and scrub that specific area again with a circular motion.

Once you have scrubbed all the targeted grout lines, it is time to remove the dirty residue. Fill your bucket with fresh, warm water and grab your clean cloths or towels.
Dip a cloth into the warm water, wring it out slightly so it is damp rather than soaking wet, and wipe away the grey paste from the tiles and grout. Rinse your cloth frequently in the bucket of clean water to avoid simply smearing the dissolved dirt back across the surface. For vertical walls, wipe from the top down so the dirty water flows toward areas you have not yet cleaned or directly down to the floor. For floors, use a freshly rinsed mop or a damp towel to pick up the remaining baking soda slurry.

Inspect the results and dry the space
Take a close look at the grout lines under bright bathroom lighting to check your work. While scrubbing without bleach may not alter the original, permanent dye lot of aging grout, it should successfully remove the surface layer of dirt, dark mildew spots, and greasy buildup, leaving the lines significantly brighter and more uniform in color.
If you find small patches that still look dark, you can repeat the paste application and scrubbing process specifically on those isolated spots rather than redoing the entire room.
Finally, take a dry microfiber towel and thoroughly dry the entire surface. Drying the area removes excess ambient moisture that would otherwise encourage mold spores to settle back into the damp, newly cleaned porous grout. Leaving the bathroom well-ventilated by turning on the exhaust fan or opening a window for a while will help the room dry completely and keep your newly cleaned grout looking fresh for a much longer time.
