The answer to 'when to clean tile' is that tile should be cleaned on a regular basis, typically every 6-12 months, to maintain its appearance and prevent buildup of dirt, grime, and stains. Proper tile cleaning helps extend the life of your tile and grout, and keeps your floors looking their best.
Regular tile cleaning involves sweeping or vacuuming to remove loose dirt, followed by mopping with a mild, pH-neutral cleaner designed for tile and grout. You may also need to use a stiff-bristle brush or grout brush to scrub the grout lines. For heavily soiled areas or tough stains, you may need to use a tile-safe degreaser or acidic cleaner.
