The answer to 'why is my grout stained' is that grout can become discolored and stained over time due to a variety of factors. Grout is a porous material that can easily absorb dirt, grime, and spills, leading to unsightly stains. Common causes of grout stains include food and beverage spills, soap scum buildup, mold and mildew growth, and improper cleaning methods.
To address grout stains, you can try DIY cleaning methods like using a grout cleaner or a mixture of baking soda and water. However, for more stubborn stains or if the grout is in poor condition, it's best to call in a professional cleaning service. They have the right tools and expertise to deep clean and restore the grout, ensuring a long-lasting, clean finish.
