The answer to 'why is my tile buildup' is that tile and grout can accumulate dirt, grime, and mineral deposits over time. Common causes include regular foot traffic, spills, and hard water. Symptoms include discolored, dingy-looking tiles and grout that may feel rough or textured.
The good news is that tile buildup can often be removed through a combination of cleaning products and techniques. For light to moderate buildup, homeowners may be able to DIY with the right tools and cleaners. However, for heavy or stubborn buildup, it's best to call in a professional tile cleaning service to ensure the job is done thoroughly and safely.
