Take your stiff-bristled brush and scrub back and forth along the lines. Apply firm, steady pressure, letting the tips of the bristles dig down into the recessed channels. You should see the cleaning solution change color as it lifts trapped dirt out of the porous mortar.

Work systematically across the room, section by section. Hold your brush or applicator steady and trace the lines carefully. You do not need to worry about being messy on the edges; a little bit of overlap onto the actual tile face is completely normal and expected at this stage.

Wipe Excess Pigment from the Tiles

Allow the applied colorant to sit for the duration specified by the instructions on your container, usually around thirty to forty-five minutes. Do not let it cure completely hard before addressing the excess, or removal will become difficult.

Take a damp sponge—wrung out so it is moist rather than dripping wet—and gently wipe across the tiles. The moisture softens the excess pigment that landed on the tile surface during the application phase. Wipe diagonally across the lines rather than parallel to them, as moving parallel risks catching the edge of your sponge in the recessed joint and wiping away the fresh pigment you just applied.

Rinse your sponge frequently in a bucket of clean water. Change the water as soon as it becomes cloudy. As you wipe the tiles, check your progress to ensure the pigment remains inside the joints while the tile faces emerge clean and shiny.
