Before You Start

Step-By-Step: How To Clean A Bathtub With Baking Soda

Rinse the tub with warm water to loosen soap scum and soften grime.
Sprinkle baking soda generously on damp surfaces, focusing on stained or discolored areas.
Prepare a light cleaning paste by mixing baking soda with a small amount of water until a thick consistency forms.
Use the non-scratch bath scrub brush to scour circular motions over the paste, applying moderate pressure.
For stubborn stains, let the paste sit for 5–10 minutes before scrubbing again with the abrasive sponge scrub pad.
Rinse thoroughly with warm water, ensuring all baking soda residue is removed from corners and drains.
Wipe the tub dry with microfiber cloths to prevent water spots and streaks.
Inspect for remaining grime. Repeat the process on any persistent spots as needed.
For grout lines, apply a small amount of paste to the vertical surfaces and scrub gently with the brush.
Finish by a final rinse and dry to maintain a bright, clean appearance.
Optional: alternate with a mild vinegar spray for extra deodorizing before the final rinse.
Store baking soda and cleaning tools in a dry, accessible area for quick future touch-ups.
