Mould, a ubiquitous challenge many homeowners face, can be particularly prevalent in moisture-rich environments like bathrooms and kitchens. Beyond its unsightly appearance, mould can pose significant health risks, including respiratory issues and allergic reactions. Understanding how to effectively eliminate existing mould and implement preventive measures is crucial for maintaining a healthy living environment. This comprehensive guide delves into proven techniques to clean mould from kitchens and bathrooms and offers invaluable tips to ensure your home remains mould-free.

How to Clean Mould in Kitchens and Bathrooms

How to Clean Mould in Bathrooms and Kitchens?

Mould in bathrooms and kitchens is not only unsightly but can also pose health risks if left unchecked. Depending on how serious the problem is, we have the best 2 solutions for you below.

1. How to Use White Vinegar to Clean Mould

White vinegar, renowned for its acidic properties, is not only an eco-friendly cleaning agent but also particularly very good to use against mould. Its natural acidity works to penetrate and break down mould, making it easier to scrub away.

Step-by-step Process

  1. Preparation: Start by creating a solution of equal parts distilled white vinegar and water. Pouring this mixture into a spray bottle will make the application process smoother.
  2. Application: Target the mouldy patches and spray generously, ensuring the vinegar solution covers all affected areas.
  3. Waiting Period: Once applied, patience is key. Let the solution settle for at least an hour. This duration allows the acidic properties of the vinegar to weaken the mould’s structure.
  4. Scrubbing: After the wait, use a stiff-bristled brush or a robust sponge to scrub the mould away. Remember to apply some elbow grease for stubborn patches.
  5. Clean-up: Once you’ve scrubbed the areas, use a damp cloth to wipe away the mould remnants and any leftover solution.
  6. Reapplication: If you still notice mouldy patches, don’t hesitate to repeat the process. Sometimes, particularly stubborn mould might require a couple of rounds of treatment.

Safety Precautions

Mould isn’t just unsightly; it can be harmful. Hence, whenever you’re dealing with it, ensure you’re wearing protective gloves and a mask. These precautions will shield you from direct contact, potential allergic reactions, and inhaling mould spores.

2. Commercial Mould and Mildew Cleaners for Cleaning Mould

While natural remedies work wonders, some mould infestations require a stronger approach. Commercial mould and mildew cleaners, formulated with powerful ingredients, can be the solution for those stubborn and extensive mould patches.

Guidelines for Using Commercial Cleaners:

  1. Choosing the Right Product: A visit to your local DIY or home improvement store will present you with various mould cleaner options. Select one that’s best suited for your needs.
  2. Reading the Label: Before using the product, carefully read and understand all the instructions. This ensures you achieve the best results without inadvertently causing harm or damage.
  3. Safety First: Many commercial cleaners contain potent chemicals. Ensure you work in a well-ventilated area. Open windows, switch on exhaust fans or use the cleaner outdoors if possible.
  4. Following Manufacturer’s Instructions: Always stick to the recommended application procedure, duration, and clean-up method. Overusing or letting the cleaner sit for longer than suggested can sometimes lead to discolouration or damage to surfaces.

How to Prevent Mould in Kitchens and Bathrooms?

Drain unblocker chemicals can help to dissolve and break up stubborn blockages. However, these chemicals should be used with caution, as they can be harmful to the environment and may damage the drain if not used correctly.

1. Control Humidity Levels

Mould thrives in humid environments. By maintaining an indoor humidity level between 30 and 50 percent, you greatly reduce the chance for mould to establish itself. If certain areas of your home, such as bathrooms or basements, consistently feel damp or have a musty odour, it might be time to invest in a dehumidifier.

These devices help extract excess moisture from the air, making environments less favourable for mould growth.

2. Prompt Leak Repairs

Water leaks, whether from faulty plumbing or external intrusions, can lead to prolonged damp conditions. Such wet environments are prime real estate for mould to flourish. Regularly inspect areas around your plumbing fixtures, ceilings, and walls. If you notice any signs of leakage, it’s crucial to address them without delay.

Not only does this mitigate mould risks, but it also saves on potential repair costs in the future.

3. Ensure Proper Ventilation

Effective ventilation ensures a consistent exchange of indoor and outdoor air, effectively reducing moisture levels in your home. Areas that generate a lot of moisture, like bathrooms from showers or kitchens from cooking, particularly benefit from proper ventilation.

Household appliances, like clothes dryers, produce moisture during operation. Ensure these appliances vent outside your home to prevent an accumulation of indoor humidity.

4. Routine Cleaning and Maintenance

By maintaining a regular cleaning schedule, you can catch and address early signs of mould. Regularly cleaning surfaces with a white vinegar solution not only cleans but also acts as a preventive measure against mould establishment.

If surfaces begin to display mildew or mould, consider escalating your cleaning approach. A solution of one cup of chlorine bleach mixed with one gallon of water can effectively treat these early infestations.

5. Rethink Carpets in Damp Zones

While carpets offer comfort and aesthetic appeal, they can trap and hold moisture. In areas prone to dampness, this makes them breeding grounds for mould.

For bathrooms, basements, or other damp-prone zones, consider alternatives like tiles, vinyl, or specially treated wood flooring.

6. Insulation is Key

Cold surfaces can lead to condensation. When warm, moist air contacts cooler surfaces like pipes or poorly insulated walls, water droplets form, providing the moisture mould needs.

By properly insulating pipes, walls, and other potential condensation points, you remove the conditions mould needs to thrive.

7. Stay Vigilant

Mould is sneaky. Periodic inspections, especially in known problem areas, can help you identify and address potential mould issues before they escalate.

Discovering a mould patch during your inspections? Address it immediately. Swift action often results in easier cleaning and less potential health risk.


Mould can be both unsightly and detrimental to health. By employing both effective removal techniques and proactive preventive measures, you can ensure a clean, mould-free environment in your home, safeguarding your health and maintaining the aesthetic appeal of your interiors.

Frequently Asked Questions

What causes mould to grow in kitchens and bathrooms?

Mould thrives in moist and humid environments. Activities like cooking, showering, or even a leaking faucet can introduce excess moisture, making kitchens and bathrooms ideal places for mould to grow.

Is mould in my kitchen or bathroom dangerous?

Some mould types can produce allergens, irritants, or even toxins. Prolonged exposure can lead to respiratory issues or allergic reactions, especially in susceptible individuals.

How can I distinguish mould from mildew?

While both are fungi, mildew typically appears as a flat, powdery substance and can be white or grey. Mould, on the other hand, is often raised, fuzzy, and can appear in various colours, including black, green, or red.

Can I use natural products to remove mould?

Yes! A mixture of equal parts white vinegar and water is an effective natural remedy for many mould types.

Are commercial mould removers safe?

While they can be effective, many commercial mould removers contain strong chemicals. It’s essential to use them in well-ventilated areas, wear protective gear, and always follow the manufacturer’s instructions.

Why does mould keep returning to my bathroom?

Persistent mould often indicates an unresolved moisture issue. Check for undetected leaks, ensure adequate ventilation, and maintain dry conditions to prevent regrowth.

Can I paint over mould to hide it?

Painting over mould doesn’t resolve the problem; it merely hides it. It’s crucial to clean and remove mould first. Thereafter, you can use mould-resistant paint to prevent future growth.

How can I prevent mould growth in my kitchen and bathroom?

Maintain low humidity levels (between 30-50%), fix leaks promptly, ensure good ventilation, and clean regularly with mould-resistant products.

Is bathroom mould the same as the mould found on food?

While both are fungi, they usually belong to different species or strains. The mould you see on food is due to spoilage, while bathroom mould thrives on persistent moisture and organic materials like soap scum.

Do I need a professional to remove mould?

For small areas, DIY methods often suffice. However, if you’re dealing with extensive mould growth, especially in areas hard to reach, or if the mould returns repeatedly despite cleaning, it might be wise to seek professional help.
