The answer to 'why is my tile dirty' is that there are several common causes, including improper cleaning, buildup of dirt and grime, and damage to the tile or grout. Symptoms may include discoloration, stains, and a dull or hazy appearance.
To address a dirty tile floor, you can try DIY cleaning methods like sweeping, mopping with a tile-safe cleaner, and scrubbing with a stiff brush. However, for more stubborn dirt, deep cleaning, or tile restoration, it's best to call in a professional tile cleaning service.
