Moldy shower tray, how to fix it: just pour this

A moldy shower tray is every homeowner’s nightmare. The bathroom, in general, is one of the most challenging areas to clean—high humidity, soap residue, and limited ventilation create the perfect environment for mold to grow. Even with regular cleaning, it often feels like detergent and water alone just aren’t enough to keep it spotless.

Luckily, you don’t need harsh chemicals or expensive products to restore your shower tray’s shine. With a few natural ingredients that you probably already have at home, you can remove mold, eliminate odors, and bring back that fresh, clean look to your bathroom. Let’s see how!


Why Mold Grows on the Shower Tray

Mold thrives in warm, damp places—exactly the kind of environment a shower creates. Water splashes, soap residue, and poor air circulation lead to persistent humidity, which encourages mold spores to spread and cling to corners, joints, and surfaces. Over time, this buildup not only looks unpleasant but can also damage the surface of the tray and grout.

The good news is that natural remedies can work wonders in breaking down mold and disinfecting these areas, leaving your shower looking like new.


Step 1: The Power of Baking Soda

The first ingredient to reach for is baking soda, a timeless cleaning solution that our grandmothers used for its stain-removing, deodorizing, and sanitizing properties. It’s gentle on surfaces yet tough on grime and mold.

To create a powerful cleaning paste, mix four cups of water with one cup of baking soda. Stir slowly until you form a thick, creamy consistency.

Apply this paste directly to the moldy areas of the shower tray, spreading it evenly. Let it sit for at least 10 minutes to allow the mixture to loosen dirt and absorb moisture.

Then, using the rough side of a sponge, gently scrub the surface, especially in corners or crevices where mold tends to accumulate. Finally, rinse thoroughly with warm water.

After rinsing, you’ll notice that your shower tray looks cleaner, brighter, and fresher. This simple method is ideal for regular maintenance too—it helps prevent new mold from forming.


Step 2: Using Vinegar for Stubborn Mold

If the stains are more stubborn, move on to another natural cleaning champion: white vinegar. Vinegar is a powerful degreaser, disinfectant, and deodorizer. It’s often used to whiten laundry, remove stains, and neutralize unpleasant odors—and it works just as effectively in the bathroom.

To prepare the cleaning spray, mix equal parts of vinegar and water in a spray bottle. Shake well, then spray the solution generously over the entire shower tray, paying special attention to the moldy and dirty areas.

Let it sit for a few minutes so that the vinegar can break down the mold and mineral deposits. Then scrub gently with a sponge and rinse with warm water.

Not only will this method remove visible mold, but it will also help prevent it from coming back thanks to vinegar’s natural antifungal properties.


Step 3: The Citric Acid Trick

If you prefer a lighter scent and a more eco-friendly approach, citric acid is a great alternative to vinegar. Known for its cleaning and descaling power, it’s gentle on surfaces yet incredibly effective against limescale, soap scum, and mold.

Mix 150 grams of citric acid with one liter of water and pour the mixture directly onto the shower tray. Let it sit for about two minutes, then scrub using a non-abrasive sponge. This prevents scratches on the shower tray while lifting away dirt and stains.

Citric acid not only removes mold but also leaves a pleasant, natural freshness behind—perfect for regular cleaning routines.


Step 4: Lemon – The Natural Brightener

Another great natural cleaner is lemon juice. Lemon has strong degreasing and whitening properties, making it ideal for cleaning and sanitizing bathrooms. Plus, its refreshing fragrance gives your bathroom a lasting clean scent.

There are two effective ways to use lemon on your shower tray:

  1. Lemon and Baking Soda Paste
    Mix half a cup of lemon juice with four tablespoons of baking soda. The mixture will start to fizz slightly—this reaction helps loosen dirt and kill mold. Apply the paste directly onto the moldy areas and scrub using an old toothbrush to reach tight corners. Rinse thoroughly afterward.

  2. Pure Lemon Wipe
    Alternatively, squeeze the juice of one lemon and filter it. Soak a clean cloth or sponge in the juice and use it to wipe the affected areas. Leave it on for one hour before rinsing with plenty of water. This method is great for giving your shower tray a bright, polished finish.


Step 5: The Cotton Trick That Never Fails

Few people know this clever method, but it’s extremely effective—especially for deep mold removal. It involves using cotton balls soaked in a homemade disinfecting solution.

To prepare it, combine:

  • 400 ml of water

  • 2 tablespoons of hydrogen peroxide

  • 2 tablespoons of baking soda

  • 1 tablespoon of fine salt

Dissolve the salt and baking soda in water and bring the mixture to a boil. Once it starts bubbling, remove it from heat and add the hydrogen peroxide. Stir until smooth and allow it to cool slightly.

Soak cotton balls in the mixture—without squeezing them—and place them directly on the moldy areas of the shower tray. Leave them there for about one hour to allow the solution to penetrate and dissolve the mold. Afterward, remove the cotton, scrub lightly if necessary, and rinse thoroughly.

This method works wonders because hydrogen peroxide disinfects deeply, baking soda cleans, and salt helps lift grime. Together, they leave the surface sanitized and spotless.


A Fresh, Sparkling Shower—Naturally

With these natural, homemade solutions, your shower tray will regain its original shine and freshness without using any harsh chemicals. Each method uses simple, affordable ingredients that are safe for you, your family, and the environment.

Once cleaned, your bathroom will smell pleasant and fresh without the need for synthetic air fresheners. These eco-friendly remedies not only make cleaning easier but also help prevent mold from returning—keeping your shower area spotless, healthy, and inviting every day.

So next time you notice mold creeping into your shower tray, skip the store-bought cleaners and try one of these simple tricks. You’ll be amazed by how effective natural ingredients can be!
