Bathrooms are naturally warm and humid, the perfect breeding ground for mildew, a type of surface fungus that thrives in damp spaces. While it may look similar to mould, mildew is typically lighter in colour (white, grey, or yellow) and flatter in texture.

Left untreated, mildew can leave stubborn stains, unpleasant smells, and even damage grout or paint. The good news? It’s easier to remove than deep-set mould if you act quickly.

This guide covers how to get rid of mildew in your bathroom, what causes it, and how to stop it from returning — with practical tips for every UK home.

1. What Causes Mildew in Bathrooms?

Mildew forms when moisture lingers on surfaces that don’t dry out properly.

Main causes include:

• Poor ventilation (no extractor fan or blocked vents)

• Condensation on tiles, ceilings, and windows

• Lack of regular cleaning or drying after showers

• Leaky taps or pipes creating damp spots

• Old grout or sealant that traps water underneath

💡 Mildew often appears first on grout lines, silicone seal, shower curtains, or ceilings above the bath.

2. How to Tell the Difference Between Mould and Mildew

💡 If it wipes away easily, it’s likely mildew; if it returns quickly or stains, it could be mould.

3. Step-by-Step: How to Remove Mildew in Your Bathroom

Step 1: Prepare the Area

• Open windows and turn on the extractor fan.

• Wear gloves and a face mask to avoid spores or fumes.

Step 2: Choose a Cleaning Method

Option A — Vinegar & Baking Soda (Natural Solution)

1. Mix equal parts white vinegar and water in a spray bottle.

2. Spray generously on affected areas and leave for 30 minutes.

3. Scrub gently with an old toothbrush.

4. For tougher stains, sprinkle baking soda on top of the vinegar and scrub again.

5. Rinse and dry the area thoroughly.

Option B — Commercial Mildew Remover

Use a specialist cleaner like:

• Dettol Anti-Bacterial Mould & Mildew Remover

• HG Mould Spray

Apply following the manufacturer’s instructions and wipe clean.

4. How to Remove Mildew from Grout, Tiles, and Sealant

Mildew often hides in grout and silicone around baths and showers.

• Use a grout brush or toothbrush dipped in vinegar or mildew remover.

• Let it sit for 10–15 minutes before rinsing.

• For badly discoloured or damaged sealant, replace it completely.

5. How to Prevent Mildew from Coming Back

Improve Ventilation

• Use an extractor fan while showering and for 15 minutes afterwards.

• Open windows whenever possible.

• Leave doors ajar to let air circulate.

👉 Book Electrical Services for extractor fan installation or upgrades.

Keep Surfaces Dry

• Wipe down tiles, mirrors, and shower screens after use.

• Shake out and wash shower curtains weekly.

• Remove damp towels from the bathroom quickly.

Control Humidity

• Use a small dehumidifier or moisture absorber in windowless bathrooms.

• Keep a regular cleaning routine with anti-fungal sprays.

💡 Maintaining airflow and dryness is the best way to keep mildew away permanently.
