Mould on bathroom tiles is a common yet frustrating problem. Not only is it unsightly and unhygienic, but it can also cause respiratory issues and trigger allergies. The good news? You don’t need a full renovation to get rid of mould — just the right tools, methods, and a bit of elbow grease.
In this article, we’ll show you the most effective and safe ways to remove mould from bathroom tiles, both naturally and with store-bought cleaners. 🧽✨
🦠 Why Does Mould Grow on Bathroom Tiles?
Mould thrives in damp, warm, and poorly ventilated environments — a perfect description of most bathrooms. Tiles, especially the grout lines, tend to absorb moisture, which encourages mould spores to grow.
Common causes include:
-
Lack of ventilation
-
Frequent hot showers
-
Leaking pipes or taps
-
Dirty or unsealed grout
🛠️ What You’ll Need
Before you start, gather these essentials:
-
Rubber gloves 🧤
-
Old toothbrush or grout brush
-
Spray bottle
-
Microfiber cloths or sponge
-
Mould remover (store-bought or DIY)
-
Protective mask 😷 (optional but recommended)
🧪 Method 1: Use White Vinegar (Natural & Effective)
✅ Steps:
-
Pour white vinegar (undiluted) into a spray bottle
-
Spray directly onto affected tiles and grout
-
Let it sit for 30–60 minutes
-
Scrub with a brush in circular motions
-
Rinse thoroughly with warm water
-
Wipe dry with a clean cloth
💡 Tip: Repeat once a week for prevention.
🧂 Method 2: Baking Soda + Water Paste
A gentle yet powerful solution for light mould.
✅ Steps:
-
Mix baking soda with water until it forms a thick paste
-
Apply to mouldy areas with a brush
-
Scrub in and let sit for 10–15 minutes
-
Spray vinegar over the paste — it will fizz 🔬
-
Scrub again, rinse, and dry
🧼 This method is great for regular maintenance!
🧴 Method 3: Hydrogen Peroxide (3%)
Stronger than vinegar and baking soda, peroxide kills mould spores at the root.
✅ Steps:
-
Pour 3% hydrogen peroxide into a spray bottle
-
Spray affected areas and let it sit for 10 minutes
-
Scrub with a brush, rinse, and dry
⚠️ Avoid using hydrogen peroxide and vinegar together — it can be unsafe.
🛒 Method 4: Commercial Mould Removers
There are many products on the market specifically for bathrooms, such as:
-
HG Mould Spray
-
Tilex Mold and Mildew Remover
-
Cillit Bang Black Mould Remover
✅ Steps:
-
Apply product as per instructions
-
Let sit for recommended time
-
Scrub if needed, rinse thoroughly
-
Ventilate bathroom during and after use
⚠️ Use gloves and ensure proper ventilation when working with chemicals.
🧱 What About Re-Sealing Grout?
Sometimes, cleaning isn’t enough. If grout remains stained or crumbles, consider:
-
Removing and replacing grout
-
Sealing new grout with a water-resistant sealant
-
Using mould-resistant grout in humid areas
🛠️ This ensures long-term protection and a fresh look.
🌬️ How to Prevent Mould from Returning
-
✅ Use an extractor fan during and after showers
-
✅ Keep a window slightly open when possible
-
✅ Dry tiles and grout after use
-
✅ Apply anti-mould spray weekly
-
✅ Wash shower curtains and bath mats regularly
🚫 What NOT to Use
-
❌ Bleach alone – while it kills surface mould, it doesn’t always kill spores
-
❌ Metal brushes – can damage tiles and grout
-
❌ Mixing cleaning agents (e.g., bleach + vinegar or ammonia) – creates toxic fumes
💬 Final Thoughts
Removing mould from bathroom tiles doesn’t have to be overwhelming. Whether you prefer natural remedies or heavy-duty cleaners, consistency is key. With regular maintenance and proper ventilation, your bathroom can stay clean, fresh, and mould-free! 💧🛁
