How to Remove Mould & Mildew from Shower Curtains Naturally

 

Introduction

Mould and mildew on shower curtains are more than just an eyesore—they’re a common bathroom problem caused by moisture, warmth, and poor ventilation. Studies show that over 70% of household mould growth starts in bathrooms, making shower curtains one of the most affected items. The good news? You don’t need harsh chemicals or expensive cleaners to fix it.

In this guide, you’ll learn how to remove mould & mildew from shower curtains naturally using safe, effective, and budget-friendly methods. These solutions work for plastic, vinyl, and fabric shower curtains, and they’re ideal for homes with kids, pets, or sensitivities to chemical cleaners.

Keeping your bathroom fresh isn’t just about surfaces—learning how to clean your shower curtain in the washing machine with vinegar helps prevent odours, mould, and bacteria buildup.

What Causes Mould & Mildew on Shower Curtains?

Before cleaning, it helps to understand why mould forms so easily on shower curtains.

Common causes include:

• Constant moisture from daily showers

• Warm bathroom temperatures (ideal for mould growth)

• Poor airflow or ventilation

• Soap scum and body oils, which feed mould spores

Mould spores can start growing within 24–48 hours in damp conditions, especially on plastic and vinyl surfaces.

Why Choose Natural Cleaning Methods?

Many commercial mould cleaners contain bleach or ammonia, which can:

• Release toxic fumes

• Damage fabric curtains over time

• Trigger allergies or respiratory irritation

Natural cleaning methods are:

• Non-toxic and eco-friendly

• Safe for regular use

• Cost-effective (most ingredients are already in your kitchen)

According to environmental health experts, vinegar and baking soda can kill up to 82% of mould species on non-porous surfaces.

How to Remove Mould & Mildew from Shower Curtains Naturally

1. White Vinegar: The Most Effective Natural Solution

White vinegar is acidic, making it highly effective at killing mould and mildew at the root.

How to use:

1. Fill a spray bottle with undiluted white vinegar.

2. Spray directly onto mouldy areas

3. Let it sit for 30–60 minutes.

4. Scrub gently with a soft brush or sponge

5. Rinse with warm water and air dry

Best for: Plastic, vinyl, and fabric shower curtains
Pro tip: Don’t rinse immediately—vinegar works better with time.

2. Baking Soda for Deep Cleaning & Odour Removal

Baking soda is a natural deodoriser and mild abrasive that helps lift stains and residue.

Steps:

• Mix ½ cup baking soda + warm water to form a paste

• Apply to mouldy spots

• Scrub gently

• Rinse thoroughly

For extra strength, combine baking soda with vinegar (expect fizzing—this is normal).

3. Lemon Juice: Natural Bleaching Power

Lemon juice contains citric acid, which naturally breaks down mould and lightens stains.

How to apply:

• Squeeze fresh lemon juice onto affected areas.

• Leave in sunlight for 1–2 hours

• Rinse and dry

Bonus: Leaves a fresh, clean scent
Best for: Light mildew stains and fabric curtains

4. Hydrogen Peroxide (3%) for Stubborn Mould

Hydrogen peroxide is a natural antifungal agent often used in eco-cleaning.

Method:

• Pour 3% hydrogen peroxide into a spray bottle.

• Spray mouldy areas

• Let sit for 10–15 minutes

• Scrub and rinse

This method can remove up to 90% of visible mould stains on non-porous surfaces.

How to Clean Fabric Shower Curtains Naturally

Fabric curtains trap moisture more easily, making them prone to mildew.

Washing machine method:

• Place the curtain in the washer.

• Add 1 cup white vinegar to the detergent compartment.

• Use warm water on a gentle cycle

• Air dry completely

Avoid the dryer—heat can damage fabric fibres and set stains permanently.

How to Clean Plastic or Vinyl Shower Curtains

Plastic and vinyl are easier to clean but still require proper care.

Natural hand-wash method:

• Lay the curtain flat in a tub.

• Sprinkle baking soda on mouldy areas.

• Spray vinegar on top

• Scrub gently

• Rinse with warm water

For maintenance, wipe the curtain weekly with diluted vinegar.

Common Mistakes to Avoid

Avoiding these mistakes can prevent mould from returning:

• ❌ Using bleach alone (it doesn’t kill mould roots)

• ❌ Skipping drying after cleaning

• ❌ Leaving curtains bunched up after showers

• ❌ Ignoring bathroom ventilation

Experts recommend keeping bathroom humidity below 50% to reduce mould growth.

How to Prevent Mould & Mildew from Coming Back

Simple prevention tips:

• Pull the curtain fully closed after each shower.

• Use an exhaust fan for 20–30 minutes.

• Wash shower curtains once a month.

• Spray vinegar weekly as maintenance

• Choose mould-resistant fabric or liners

Preventive care can reduce mould buildup by up to 60% annually.

Natural Cleaning Schedule (Recommended)

• Weekly: Vinegar spray wipe-down

• Monthly: Deep clean with vinegar or baking soda

• Every 6–12 months: Replace liner if needed

This routine keeps your bathroom hygienic and odour-free.

Health Risks of Mouldy Shower Curtains

Long-term exposure to mould can cause:

• Allergic reactions

• Asthma flare-ups

• Skin irritation

• Musty odours spreading through your bathroom

The CDC notes that mould exposure can worsen respiratory conditions, especially in children and older adults.

Conclusion: Clean, Safe & Chemical-Free

Learning how to remove mould & mildew from shower curtains naturally helps you maintain a cleaner, healthier bathroom without harsh chemicals. With simple ingredients like vinegar, baking soda, and lemon juice, you can eliminate mold, prevent regrowth, and save money—all while protecting your home environment.
