HOW TO SAFELY USE BAKING SODA IN YOUR BATHROOM
Baking soda is an eco-friendly alternative to harsh chemical cleaners. While it is generally safe for use on most surfaces, caution should be exercised due to its mild abrasive properties. Below is an overview of surfaces that are generally considered safe for baking soda use, alongside those that should be avoided. It is advisable to perform a spot test prior to usage.
Safe Surfaces:
- Porcelain (toilets, sinks)
- Ceramic tile
- Glass shower doors
- Grout lines
- Chrome fixtures (when used gently)
- Plastic shower curtains
- Vinyl flooring
Surfaces to Avoid:
- Natural stone (marble, granite, limestone)
- Wood surfaces
- Unsealed grout
- Antique or gold-plated fixtures
- Deeply scratched surfaces
REQUIRED INGREDIENTS
Baking soda. Also known as sodium bicarbonate, baking soda is a powerhouse ingredient that isn’t just for baking or removing unpleasant odors – it’s a natural cleaning superhero that can transform your grimy tubs and streaky sinks into sparkling surfaces.
Liquid castile soap. Unlike harsh chemical cleaners that strip everything in their path, castile soap maintains a delicate balance: tough enough to dissolve bathroom scum but gentle enough to preserve the natural oils in your skin if you get some on your hands. It is super concentrated – a little of this soap goes a long way!
Essential oils. I tend to use my trusty lemon essential oil (for degreasing and fresh scent). Feel free to substitute with drops of your favorite essential oil.

DIY BATHROOM SCRUB RECIPE
Reminder: Avoid using this scrub on natural stone surfaces like marble or granite as the baking soda can be too abrasive for these materials. Always test on a small, inconspicuous area first.
- 1/4 cup baking soda
- 1 tablespoon liquid castile soap (unscented)
- 4 drops lemon essential oil
- cool water (as needed, to achieve desired consistency)
INSTRUCTIONS
HOW TO MIX UP DIY SCRUB
- In a small bowl, combine the baking soda and liquid castile soap
- Add the essential oils
- Gradually add small amounts of water while stirring until you reach a smooth, thick paste consistency (similar to cake frosting)


APPLICATION INSTRUCTIONS
- Dampen the surface you want to clean
- Apply the scrub with a damp sponge or scrub brush using circular motions
- Let sit for 1-2 minutes
- Scrub gently
- After cleaning, rinse surfaces thoroughly with clean water to prevent any residue from building up
- For best results, wipe any faucet handles or spouts with a clean cloth to avoid remaining water spots

I have this electric spin scrubber that I absolutely love for cleaning my tub/shower. It has a handle that extends, making it simple to get into those hard-to-reach areas.

OPTIONAL VARIATIONS
- If you do not have liquid castile soap on hand, substitute with a natural dish soap instead.
- Include washing soda alongside baking soda (in a 50/50 ratio) for enhanced cleaning power.
- Add hydrogen peroxide to increase disinfecting properties and whitening power.
PRO TIPS
- For stubborn stains or mineral deposits, allow the soda paste to sit on affected area for 10-15 minutes before scrubbing gently in a circular motion.
- Never mix castile soap with vinegar – choose one or the other. When combined, the vinegar breaks down the castile soap back to its original oils. Instead of getting a super-cleaner, you end up with a goopy, curdled mess that looks somewhat like cottage cheese floating.
- While baking soda is generally safe, using too much pressure when scrubbing can damage any surface, so always start gentle and increase pressure only if a little extra scrubbing power is needed.
- This recipe makes a sufficient amount to clean the double sinks, bathtub surface, and shower walls in our bathroom. Mix up just enough to clean your bathroom so there is zero waste. I do not recommend making large quantities of the mixture and storing for future use.
- It is also a great homemade cleaner for a stainless steel kitchen sink or garbage disposal.
Isn’t it amazing how such simple ingredients can make the best household cleaners? In today’s world where we are bombarded with countless harmful chemicals, it’s important to take a step back and consider natural alternatives. And when it comes to cleaning our bathrooms, there’s no need to turn to harsh chemicals when a simple and effective DIY solution exists.
