Instead, let the paste sit undisturbed for a significant duration, typically ranging from thirty minutes to a couple of hours depending on how severe the mark is. Cover the paste with a piece of plastic wrap if you are worried about it drying out too quickly, which maintains the chemical activity of the mixture. As the paste rests, it draws the embedded pigments and minerals out of the tile pores and into the cleaning medium.

Scrub gently and rinse thoroughly

After the dwell time has elapsed, take a soft-bristored brush or a non-scratch nylon scrubbing pad and gently work the paste in circular motions across the stained areas. Pay special attention to textured tiles where the discoloration tends to anchor itself tightly within the grooves and depressions. Avoid using stiff metal brushes, steel wool, or harsh abrasive pads, as these can permanently scratch the glazed surface of porcelain tiles and create new crevices where dirt will accumulate in the future.

Once you have worked through all the stained spots, rinse the entire surface thoroughly with plenty of warm water to wash away the loosened debris and spent cleaning paste. Use a clean sponge or a wet cloth to remove any lingering residue, making sure no paste remains in the corners or grout lines. Finally, dry the tiles completely with a soft towel to prevent water spots from forming and to inspect your work under bright lighting. If a faint shadow of the stain remains, you can repeat the process, allowing the paste a slightly longer dwell time to draw out the final layers of discoloration.
