The answer to 'grout cleaning tips' is to start by sweeping or vacuuming the grout lines to remove any loose dirt or debris. Then, use a grout brush or a small scrub brush to gently scrub the grout with a mild detergent or grout cleaner. Rinse the area thoroughly with clean water and let it dry completely. For heavily soiled or discolored grout, you may need to use a grout haze remover or a grout whitener.
It's important to clean grout regularly, typically every 6-12 months, to prevent buildup and discoloration. If the grout is in poor condition or you're unable to get it clean, it's best to call a professional cleaning service for a deep cleaning or grout restoration.
