Bathrooms are a great breeding ground for mold because of the moist atmosphere and lack of ventilation. This ugly greenish or dark-brownish spot in the grout between tiles and drywall won't just spoil the look of your walls but also can impact indoor air quality and trigger allergy symptoms. But getting rid of mold on bathroom walls doesn’t have to mean using toxic chemicals and costly equipment – it just requires the right method.

Why Does Mold Grow on Bathroom Walls?

The reason why mold occurs is moisture. Each time you use hot water while taking a shower, it turns into vapor and settles on surfaces in the bathroom. In case there is no exhaust fan that could draw the vapor out or there are any leaks from the bath or pipes, this moisture will stay trapped inside. Additionally, organic materials, such as soap and dust, will create favorable conditions for mold spores to proliferate.

Step-by-Step: How to Remove Mold from Bathroom Walls Safely

As soon as you have everything you need, go about cleaning the mold in an organized way and not by simply scrubbing randomly, which may damage both your wall and lungs.

Step 1 — Protect Yourself First

Always wear rubber gloves and a mask before cleaning the mold-infested surface, as the fungi are released into the air as soon as they are disturbed.

Step 2 — Apply a Natural Cleaning Solution

Spray the area with a cleaning solution of 50 percent white vinegar, 50 percent water. For tougher mold growth, try spreading a paste of baking soda over the area. Vinegar is slightly acidic and will kill the fungi at the roots without any harmful fumes.

Step 3 — Let It Sit

Let the cleaning solution sit on the stained area for 10-15 minutes to penetrate the mold in the hard-to-reach places such as grout and unsealed drywall.

Step 4 — Scrub Gently

Gently scrub the areas covered with the cleaning solution with a brush or toothbrush in order not to disturb the painted drywall.

Step 5 — Rinse and Dry Thoroughly

Clean the treated surface with a wet microfiber cloth and then thoroughly dry it. Excess moisture will be the main reason why mold will return after cleaning.

Natural vs. Chemical Mold Removers

Vinegar and baking soda are both excellent for daily cleaning and surface mold. Products containing bleach will work for tougher molds; however, you need to be careful and not mix them with ammonia. It’s always better to begin by using something natural and using harsher products only when it’s absolutely necessary.

How to Prevent Mold from Coming Back

Turn on the exhaust fan while you’re in the shower and after for 20-30 minutes

Use a squeegee on the shower walls and any glass surfaces after using them

Have any leaks fixed immediately when you spot them

Clean the shower curtain or liner and bathmat frequently

Seal any grout and redo caulking when it begins to crack

Regular bathroom cleaning will prevent moisture and soap buildup, which prevents a lot of the material that mold needs to survive.

When to Call a Professional

Not all mold situations can be easily tackled over a weekend. Mold that spreads to an area larger than three feet in size, that persists no matter what you do to stop it, or that is causing health problems such as asthma in a member of the family requires professional help. It seems like more property owners are combining the DIY cleaning approach with regular bathroom cleanings by a reputable company.

That's where the advantage of using professionals like Maids 2 Sparkle becomes apparent. Our bathroom cleanings address any moisture problems and sanitize the grout lines, preventing any mold from developing.

Frequently Asked Questions

1. Is it safe to remove bathroom mold myself?

Small surface mold on tiles, grout and such can usually be safely cleaned at home with gloves and a mask and proper ventilation. For large mold, especially in wall cavities, it’s best to hire professionals.

2. Does bleach kill mold permanently?

Bleach kills mold on nonporous surfaces like tiles, but not the roots in porous materials like drywall and grout.

3. How often should I clean my bathroom to prevent mold?

Regularly cleaning the bathroom every week, in addition to wiping down after each shower, makes it much harder for mold to take root.

4. Can mold come back after cleaning?

Unless you fix the moisture source, yes. Deep clean all you want, any leaks, poor ventilation and excess humidity will bring mold back.

5. What's the difference between mold and mildew?

Mildew is flat and powdery, and can be easily wiped off. Mold is fuzzy and slimy and can get through the surface material and be difficult to get rid of.

6. When should I hire a professional instead of doing it myself?

When mold keeps returning, is over a large area, or is affecting someone’s breathing, it’s time to call in the professionals to handle the problem.
