Use as a Tub Cleaner
Cleaning your tub requires just a few materials, which are likely already available to you. Eliminating soap scum is a straightforward task. For a fiberglass tub, you can concoct a paste using baking soda, dish soap, and water.

Spread the paste over the entire surface. According to Joshua Wakeford, a senior product associate at American Standard, you should “allow the paste to sit for at least 30 minutes before scrubbing the surface to remove the dirt, and then rinse with cold water.”
