The answer to 'how to clean grout' is to use a grout brush and a grout cleaning solution. Grout can become stained and discolored over time due to spills, dirt buildup, and mold growth. To clean it, start by sweeping or vacuuming the grout to remove any loose debris. Then, apply a grout cleaner or a mixture of warm water and baking soda to the grout lines and let it sit for a few minutes. Use a stiff-bristled grout brush to scrub the grout, working in small sections. Rinse the area with clean water and repeat the process if necessary. For tough stains or heavily soiled grout, you may need to use a stronger commercial grout cleaner or call in a professional cleaning service.
It's important to clean grout regularly to prevent it from becoming too stained or damaged. Neglecting grout cleaning can lead to the growth of mold and mildew, which can be difficult and costly to remove. If the grout is in poor condition or you're unsure of the best cleaning method, it's best to consult with a professional cleaning service for guidance.
