How to clean a bathtub with baking soda 

1. Sprinkle baking soda in the bathtub

First, fill a bucket of hot water before pouring the water all over the bathtub. Then, sprinkle baking soda generously over the bathtub, and leave for about 20 minutes. The combination of water and baking soda should start to fizzle, which means it is doing its job to lift scum. 

2. Scrub clean with soft cloth

Next, take a soft sponge or microfiber cloth to gently scrub the bathtub, and remove any soap scum or grime around the tub. Avoid using abrasive sponges, or cleaning materials that may scratch the surface. Fiberglass tubs in particular are prone to cracking, scratching, and fading over time. For stubborn stains, add a little baking soda to a toothbrush and gently scrub at the area to remove the stain.  

3. Rinse to remove grime

Once the bathtub is all clean, rinse the bathtub well with a hand sprayer or shower head to remove all traces of dirt and baking soda residue.

For a heavily soiled or grimy bathtub, put the plug in and fill the tub with hot water. Alternatively, you can just fill a spray bottle with a half-and-half solution of vinegar and warm water for mild stains.   

2. Pour vinegar into the bathtub

Next, pour two cups of white vinegar or 4-6 squirts of dish soap into the bathtub. Leave the mixture to sit in the tub for about 15-20 minutes to effectively lift the grime off. You can leave for a little longer, depending on how grimy your tub is. 

3. Drain tub and scrub well
