The best way to shine porcelain tile depends on whether it is unglazed, glazed or textured. All three types benefit from regular sweeping and cleaning, but cleaning techniques to restore the original luster vary by type.
To begin cleaning, sweep porcelain tile with a soft-bristled broom, then vacuum with a brush attachment. Use a dry dust mop on glazed or polished tiles to ensure that as much debris as possible gets removed. If the tiles are textured, sweep them twice, with the second sweeping at a right angle to the first, and vacuum after each sweeping.
If the tile is unglazed or unpolished, continue cleaning by dividing the floor into sections of 2 to 4 square feet and saturating each section with a mix of vinegar and water or a commercial cleanser. Allow the cleanser to soak in for five to 10 minutes, but do not let the tiles dry out. Scrub any stained areas with a soft-bristled brush. Wipe away any dirt and rinse the floor with clean hot water before drying with a clean towel or microfiber cloth.
If the tile is glazed or polished, follow the dry dust mop with a damp mop, using hot water. Use a mix of hot water and vinegar or a commercial cleanser diluted to half strength to scrub stains, using a soft-bristled brush. After stain removal, mop the entire floor with the vinegar mix or cleanser,and then mop a second time with hot water. Dry the tiles with a clean towel or microfiber cloth, and then buff them to a shine using cheesecloth.
If the tile is textured, saturate the floor with vinegar and water or cleanser in the same manner as the unglazed tile. Scrub each section twice with a soft-bristled brush, with the second scrubbing at right angles to the first. Rinse the floor thoroughly with hot water, and then go over it with a damp mop. Dry the tiles with a clean towel or microfiber cloth.
