To clean a bathtub effectively, start by removing any debris or residue from the surface. Then, apply a suitable cleaner, scrub the bathtub using a non-abrasive sponge or microfiber cloth, and rinse thoroughly with water. For stubborn stains, consider using specialized cleaning products or natural remedies like baking soda and vinegar.

Create a paste out of baking soda and warm water. Spread it over the tub's surface, across the floor and up the walls. Next, soak an old towel in cleaning vinegar and cover the tub's surface.

If not cleaned regularly, the bathtub can build up with soap scum, bacteria, and even mildew, which can make it look dingy. Luckily, most bathtub materials, including porcelain, fiberglass, stone resin, and acrylic, can be cleaned using household ingredients like baking soda, vinegar, and water.
