How to Clean a Bathroom with Baking Soda (Every Surface Guide)

Baking soda is a gentle abrasive and natural deodorizer that cleans, scrubs, and deodorizes bathroom surfaces without scratching. Here's how to use it effectively on every bathroom surface.

What You'll Need

• Baking soda (sodium bicarbonate)
• White vinegar (to combine with baking soda for fizzing action)
• Dish soap (to make a scrubbing paste)
• Amazon Basics Non-Scratch Sponges
• Foxtrot Living Grout Brush
• JohnBee Spray Bottles

How Baking Soda Cleans

Baking soda works in three ways: as a mild abrasive that scrubs without scratching, as a base that neutralizes acidic odors, and as a mild alkali that breaks down grease and organic matter. It's safe for all bathroom surfaces including acrylic tubs and colored grout.

Baking Soda Uses in the Bathroom

Bathtub and Shower

Sprinkle baking soda generously over the wet tub or shower floor. Add a few drops of dish soap and scrub with a non-scratch sponge. Rinse thoroughly. For a no-scrub method, mix baking soda with dish soap into a paste, apply, let sit 30 minutes, then rinse.

Toilet Bowl

Pour 1 cup of baking soda into the bowl. Let sit 30 minutes. Scrub with the toilet brush and flush. For extra cleaning power, add 1 cup of white vinegar after the baking soda and let fizz before scrubbing.

Sink

Sprinkle baking soda over the wet sink surface. Scrub with a damp non-scratch sponge. Rinse thoroughly. Baking soda removes toothpaste stains, soap scum, and light mineral deposits without scratching porcelain or ceramic.

Grout Lines

Make a thick paste of baking soda and water. Apply along grout lines. Spray with white vinegar — it will fizz. Let sit 5–10 minutes. Scrub with the grout brush. Rinse. Effective for yellowed or grey grout.

Drain Deodorizing

Pour ½ cup of baking soda down the drain. Follow with ½ cup of white vinegar. Cover the drain and let fizz for 15 minutes. Flush with boiling water. Do weekly to prevent drain odors.

Toilet Seat Stains

Make a paste of baking soda and water. Apply to yellow stains on the toilet seat. Let sit 15 minutes. Scrub with a soft cloth and rinse. Baking soda gently whitens without damaging the plastic.

Shower Curtain

Sprinkle baking soda on the curtain, spray with white vinegar, let fizz 10 minutes, scrub with a sponge, rinse. Or add ½ cup of baking soda to the washing machine when laundering the curtain.

Deodorizing the Bathroom

Place an open box or small bowl of baking soda in the bathroom to absorb ambient odors. Replace every 1–3 months. Particularly effective in bathrooms without windows.
