How To Get Rid of Black Mold in Shower

Black mold in your shower isn’t just an unsightly nuisance; it’s a health risk and a very clear sign of a bathroom with poor ventilation, high moisture levels, or both. If you’re wondering how to get rid of black mold in the shower quickly and effectively, you’ve come to the right place.

This guide from AquaBliss breaks down everything from what causes mold growth to the most effective mold removal techniques and preventative measures. So, let’s talk through how to eliminate and prevent bathroom mold so that your bathroom is sparkling clean and it no longer poses a health risk.

What Causes Black Mold in Shower?

Black mold, especially Stachybotrys chartarum, thrives in damp environments. Showers provide the perfect conditions: steam, heat, limited airflow, and lingering moisture. Combine that with soap scum and body oils on shower walls and grout lines, and you've got prime breeding grounds for mold species.

Common causes of bathroom mold include:

• Poor ventilation (no exhaust fan or window)
• Excess moisture on bathroom surfaces
• Leaky plumbing or dripping fixtures
• Infrequent cleaning, allowing mold spores to settle
• Humid climates and warm water use

Bathrooms without an exhaust fan or with a closed bathroom door trap steam, allowing moisture levels to stay high, which is ideal for mold spores to take hold and multiply.

What Materials and Tools Do You Need for Mold Removal?

Getting rid of black mold isn’t as simple as a quick scrub and you’re done - not if you want it permanently eliminated anyway. You need proper cleaning supplies and protective equipment to keep you safe as you clean it.

You’ll need to wear:

• Protective gloves
• N95 mask or respirator to avoid inhaling airborne spores
• Protective clothing and safety goggles

The cleaning supplies you’ll need:

• Spray bottle (at least 3 — one for each solution)
• Scrub brush or old toothbrush
• Soft cloth or sponge
• Warm water
• Baking soda
• White vinegar or cleaning vinegar
• 3% hydrogen peroxide
• Chlorine bleach (for serious mold stains)
• Commercial mold remover (optional)

You’ll also need to make sure your bathroom is properly ventilated. Make sure you keep your windows open or turn on the extractor fan (or both) while you clean. And, always make sure surfaces air dry completely when you’re done.

How Do You Get Rid of Black Mold in the Shower?

There’s no one-size-fits-all solution for black mold. The cleaning solution you use will depend on the severity of the mold, the type of surface, and your preference for natural or chemical methods. Below are four effective ways to clean mold.

How to Get Rid of Black Mold with Chlorine Bleach?

Chlorine bleach is ideal for nonporous surfaces like bathroom tiles and shower walls.

Steps:

1. Mix a bleach solution: 1 cup of bleach to 1 gallon of water.
2. Pour the solution into a spray bottle.
3. Spray directly onto the affected area.
4. Let the solution sit for about 10–15 minutes.
5. Scrub with a scrub brush or an old toothbrush.
6. Rinse with warm water and allow the area to air dry.

Caution: Never mix bleach with vinegar or ammonia. Bleach can discolor grout and damage silicone caulk if used excessively.

How to Get Rid of Black Mold with Hydrogen Peroxide?

Hydrogen peroxide is an excellent alternative to bleach, especially for porous materials like grout or tile grout.

Steps:

1. Pour 3% hydrogen peroxide into a spray bottle.
2. Spray the moldy area generously.
3. Allow the solution to sit for at least 10 minutes.
4. Scrub using a stiff-bristled brush.
5. Wipe clean with a damp cloth and let it air dry.

This method is great for killing mold spores without harsh fumes. Repeat the process for the remaining discoloration.

How to Get Rid of Black Mold with Distilled White Vinegar?

White vinegar is a natural and affordable option that kills up to 80% of mold species.

Steps:

1. Pour undiluted white vinegar into a spray bottle.
2. Spray directly onto moldy areas and let sit for about an hour.
3. Scrub with a brush and rinse with warm water.
4. Wipe dry with a soft cloth.

Vinegar is safe for frequent use and great for cleaning mold on bathroom tiles, shower curtains, and walls.

How to Get Rid of Black Mold with Baking Soda or Borax?

Both baking soda and borax are non-toxic and safe for children and pets. Baking soda is especially effective for light mold and lingering musty odors.

Steps:

1. Mix 1/2 cup baking soda with a few tablespoons of water to form a paste.
2. Apply to the moldy area and scrub gently.
3. Rinse with warm water and reapply as needed.
4. For extra power, combine baking soda and vinegar and let the foam lift the mold.

Borax can be mixed 1 cup per gallon of hot water for a stronger cleaning solution.

Health effects include:

• Allergic reactions (sneezing, runny nose, skin rashes)

Frequently Asked Questions About Shower Mold

Can mold grow behind shower walls?

Yes. If there are leaks or moisture buildup behind your shower tiles or wall panels, mold can grow unseen. You might notice a musty odor, discoloration, or soft drywall. In these cases, contact a professional mold remediation company to inspect the affected area.

What’s the difference between mildew and black mold?

Mildew is a surface fungus that’s usually white or gray and easy to wipe off. Black mold is darker, more stubborn, and potentially more harmful. It embeds itself into porous materials and requires more thorough cleaning.

Can a dehumidifier help in the bathroom?

Absolutely. Dehumidifiers help reduce moisture levels, especially in bathrooms without windows. Lower humidity makes it harder for mold species to grow.

Should I paint over black mold?

Never paint over mold. Paint can seal in moisture and provide more nutrients for mold to feed on. Always clean mold thoroughly first. Then, if needed, use mold-resistant paint on dry, clean surfaces.

How often should I clean my shower to prevent mold?

At least once a week. Use a mold-killing cleaner or a white vinegar spray. Wipe down surfaces daily if possible and wash your shower curtains monthly.
