How to get rid of mould safely and permanently? - Comparing DIY and Professional solutions

Mould growth on walls is a common issue in many homes and buildings, especially in humid environments like Hong Kong. Not only does it damage the aesthetics of your property, but it also poses serious health risks, such as allergies and respiratory problems. Addressing mould promptly is crucial to prevent extensive damage and mitigate these health risks. Regular maintenance and quick cleaning can help control mould growth effectively.

In this guide, we will explore effective chemicals for mould removal, top DIY solutions, and the benefits of professional mould removal services. Let’s dive in!

What Chemicals Are Effective Against Mould Growth?

Bleach

Bleach is a well-known powerhouse for killing mould on non-porous surfaces. It works quickly, disinfects, and leaves surfaces looking bright and clean. However, it's a harsh chemical that can produce toxic fumes, so it's essential to use it in a well-ventilated area and wear protective gloves and eyewear.

Bleach can also irritate the skin, eyes, and respiratory system, and it’s not effective on porous surfaces, as it can’t penetrate deeply. It’s a great option for tiles and glass but not so much for wood or drywall.

Hydrogen Peroxide

Hydrogen peroxide is another effective solution for killing mould and mildew. It doesn't produce toxic fumes and is safer for the environment, making it a gentler alternative to bleach. However, it can bleach or discolor some surfaces if not used properly and is slower acting than bleach. It’s also less effective on large mould infestations.

When using hydrogen peroxide, remember to wear protective gloves and eyewear, and store it in a dark, cool place to keep it from decomposing.

White Vinegar

White vinegar is a natural and non-toxic option, making it safe for use around children and pets. Its mild acidity makes it effective against mould, and it’s inexpensive and widely available. However, vinegar has a strong smell that some people may find unpleasant, and it may not be effective against all types of mould.

For severe infestations, you might need to apply it multiple times and still not as effective as chemicals. While generally safe, it’s a good idea to use vinegar in a well-ventilated area to avoid inhaling strong fumes.

Top 3 DIY Solutions to Remove Mould

Baking Soda and Vinegar Solution

Using baking soda and vinegar together is a natural and non-toxic way to tackle light to moderate mould infestations. Both ingredients are safe for most surfaces, but this method requires some elbow grease.

You’ll need to apply and scrub, and for more severe mould, you might find yourself repeating the process a few times. It’s a safe and effective method but be prepared for a bit of a workout.

Tea Tree Oil Spray

Tea tree oil boasts natural antifungal properties, making it a fantastic option for mould removal. It’s effective even in small quantities and safe for most surfaces.

However, tea tree oil can be on the pricier side, and its strong smell might not be to everyone’s liking. When using tea tree oil, it’s important to wear gloves to avoid skin irritation and keep it out of reach of children and pets.

Borax Solution

Borax is a reliable option for tackling mould and mildew. It not only removes mould but also acts as a deodorizer and cleaner. While it’s safe for various surfaces, it’s crucial to mix and apply it properly. Borax can be harmful if ingested, so wearing gloves and a mask during application is recommended. Also, keep it away from children and pets. Depending on where you live, borax might not be readily available.
