The Science Behind Baking Soda Cleaning
Baking soda is a mild alkaline powder. That means it reacts with grime and soap scum to break it down without harsh chemicals.
According to the American Cleaning Institute, it’s safe for most bathroom surfaces if applied gently. Unlike bleach, it won’t release toxic fumes.
The trick is using soft sponges and light pressure, which prevents micro-scratches and keeps acrylic and fiberglass shining like new.
How to Safely Use Baking Soda in Acrylic Showers
I sprinkle a little baking soda on a damp microfiber cloth, then rub in small circles over soap scum.
It’s amazing how even a few gentle swipes can lift grime. Rinse with warm water and dry with a soft towel.
The first week I did this, I was shocked at how clean the shower looked. Soft cloths + baking soda = no scratches and a sparkling shower.

How to Safely Use Baking Soda in Fiberglass Showers
Fiberglass often gets those stubborn yellow stains. I make a paste with baking soda and warm water, and spread it on the problem area.
Let it sit for 10 minutes. Then, gently wipe with a soft sponge and rinse. Fiberglass has a gel coat finish, so scrubbing hard ruins the shine.
Doing it gently keeps it clean and shiny. After trying this, I finally understood why people rave about baking soda.
How Often Should You Clean Acrylic and Fiberglass Showers?
Weekly cleaning works best. Daily wipe-downs with a microfiber cloth prevent buildup.
Baking soda is perfect for deeper cleaning every 2–3 weeks. Statista (2024) reports that 42% of homeowners clean bathrooms weekly, and they save hours in the long run.
I make it a habit after every shower to wipe the walls, and it’s a total time-saver. Your shower will stay fresh with minimal effort.

Safer Alternatives to Baking Soda
If you’re nervous about abrasives, mild dish soap and warm water are great for daily cleaning.
A vinegar-water solution works on mineral stains, but not when combined directly with baking soda.
Hydrogen peroxide tackles mildew safely. For stubborn grime, use cleaners labeled “safe for acrylic or fiberglass.”
I like to switch between baking soda and these alternatives. It keeps my shower sparkling without risking scratches.
Preventing Stains Before They Build Up
Prevention is a game-changer. After each shower, I rinse the walls with warm water and use a squeegee to remove droplets.
Soap scum forms when water evaporates. Consumer Reports found that daily rinsing cut deep cleaning time by 50%.
Doing this simple step prevents buildup and keeps cleaning quick. Trust me, once you make it a habit, your shower will stay shiny with no effort.
How to Make a Baking Soda Cleaning Routine
My routine: daily wipe with a microfiber cloth, weekly baking soda scrub, and monthly focus on grout and stubborn stains.
It keeps my acrylic shower sparkling all year. Once you establish a routine, cleaning feels effortless.
You’ll notice less buildup, fewer scratches, and more shine. It’s surprising how small, consistent steps save hours and stress later.

Baking Soda vs. Commercial Cleaners
Commercial cleaners work faster on tough stains but often contain harsh chemicals like bleach or ammonia.
These can damage acrylic or fiberglass over time. Baking soda is slower but much safer and eco-friendly.
Use an alternate week of baking soda for routine cleaning, and an occasional safe commercial cleaner for stubborn spots.
This balance keeps the shower clean without chemical exposure or scratches.
Can Baking Soda Scratch Acrylic or Fiberglass?
Technically, yes, but only if you use too much pressure or rough tools. Acrylic and fiberglass are softer than tile, so micro-scratches can appear.
Using a soft sponge or microfiber cloth prevents damage. I made this mistake once and learned that it’s not the powder but the way you use it.
Proper technique keeps surfaces scratch-free while still cleaning effectively.
Baking Soda for Odor Control in Showers
Baking soda neutralizes odors, too. Drains and damp showers often smell musty.
Sprinkle baking soda in the drain, leave for 15 minutes, then rinse with hot water. NSF testing shows baking soda removes up to 80% of musty odors.
I use this trick weekly, and my bathroom always smells fresh. It’s a small step that makes a huge difference.
