Mould in the bathroom isn’t just an eyesore—it’s a health hazard. It thrives in damp, poorly ventilated spaces and can cause respiratory issues, allergies, and structural damage over time. But the good news? You can treat bathroom mould yourself with a few smart strategies and some basic supplies.
Let’s walk through effective DIY tips for removing mould from bathroom walls and preventing it from coming back. 🧼💪
🚨 Why Does Mould Appear in the Bathroom?
Bathrooms are mould’s favorite place for three main reasons:
-
High humidity levels (especially after showers or baths)
-
Poor ventilation
-
Constant moisture on walls, ceilings, and tiles
If not cleaned and ventilated properly, mould spores multiply fast—often showing up as black, green, or brown patches on paint, grout, or even ceilings.
🧰 What You’ll Need:
-
Protective gloves and mask 😷🧤
-
Scrub brush or sponge 🧽
-
Spray bottle
-
White vinegar or hydrogen peroxide
-
Baking soda (optional)
-
Bleach (for severe mould only)
-
Microfiber cloth or old towel
-
Bucket of warm water
🔧 Step-by-Step: How to Treat Mould on Bathroom Walls
1. Protect Yourself
Before starting, open windows and wear gloves and a mask to avoid inhaling spores.
2. Choose Your Cleaning Solution
-
White vinegar – Natural and effective. Spray it directly on the mould, let it sit for 1 hour, then scrub.
-
Hydrogen peroxide (3%) – Spray on mould, wait 10 minutes, and scrub gently.
-
Baking soda & water – Create a paste for scrubbing smaller patches.
-
Bleach solution – Mix 1 part bleach with 10 parts water for tough mould. Use only in well-ventilated areas and never mix with vinegar or ammonia!
3. Scrub the Area
Use a sponge or brush to remove the mould. Don’t just wipe the surface—make sure to get into pores and cracks.
4. Rinse and Dry
Wipe the wall with clean water and dry it thoroughly with a cloth or towel.
🛑 Don’t Skip Prevention: How to Keep Mould Away
Treating the mould is half the job. Preventing regrowth is key:
✅ Improve Ventilation
-
Install or upgrade your bathroom extractor fan
-
Open windows or doors after bathing
✅ Keep Surfaces Dry
-
Use a squeegee on tiles after showers
-
Dry walls and mirrors with a towel
✅ Use Mould-Resistant Products
-
Choose mould-resistant paint
-
Use silicone sealants that contain anti-fungal properties
✅ Regular Cleaning
-
Clean your bathroom weekly with vinegar spray or anti-mould cleaner
🧼 Natural vs Chemical Solutions: Which is Better?
-
Natural options (vinegar, baking soda) are safer for kids, pets, and the environment.
-
Chemical cleaners (bleach, mould sprays) are stronger but require careful handling.
Choose based on the severity of the mould and your household preferences.
⚠️ When to Call a Professional
If mould keeps returning or covers a large area (more than 1 square meter), it may indicate:
-
Hidden leaks
-
Poor insulation
-
Structural issues
In such cases, it’s best to contact a mould remediation specialist or builder.
