How do you prevent bathtub ring?

To prevent bathtub ring, ensure you rinse the tub with clean water after each use and wipe it dry. Regularly clean the tub with mild, non-abrasive cleaners to remove soap scum and mineral deposits. Additionally, consider using bath oils or bubble baths sparingly, as these can contribute to buildup. Installing a water softener may also help reduce mineral deposits that lead to bathtub rings.
