The answer to 'tile stained' is that tile can become stained for a variety of reasons, including improper cleaning, spills, hard water buildup, and natural wear and tear over time. Tile stains can appear as discoloration, dark spots, or a dull, cloudy appearance.
Common causes of tile stains include food and drink spills, soap scum, mineral deposits from hard water, mold and mildew growth, and tracked-in dirt and grime. Symptoms may include unsightly discoloration, a rough or uneven surface, and an overall loss of the tile's original luster and shine.
For minor stains, homeowners can often DIY with a tile-safe cleaner and some elbow grease. However, for more stubborn or widespread staining, it's best to call in a professional tile cleaning service. They have the specialized equipment and expertise to safely and effectively restore your tile to its former glory.
