How to clean grout in a shower safely depends on the grout type and surrounding tile. Cement grout, epoxy grout, natural stone, ceramic, and porcelain can require different care.
Start with a cleaner recommended by the grout or tile manufacturer. Use a nylon grout brush, rinse thoroughly, and dry the area after cleaning.
Step-by-Step Method
- Ventilate the bathroom and rinse away loose soil.
- Apply a grout-compatible cleaner according to its label.
- Brush the grout with moderate pressure.
- Rinse completely with clean water.
- Dry the joints and improve ventilation.
