Understanding the Differences Between Mould, Lichen, and Algae

At Wet & Forget, we often discuss the impacts of mould, lichen, and algae on your living spaces, but what exactly are these organisms, and how do they differ from one another? Let’s dive into the specifics of each, so you can better identify and manage them in your home or outdoor areas.

What is Mould?

Mould is a type of fungus that thrives in damp, humid environments. It can be found indoors, particularly in areas with poor ventilation, such as bathrooms and basements, or near leaky windows. Mould can be dangerous to your health, especially when it triggers respiratory illnesses.

How to Identify Mould:

• Appearance: Mould can appear in various colors, including black, green, or white. It often has a fuzzy texture.
• Smell: Mould is typically associated with a musty odor.
• Common Locations: Bathrooms, kitchens, around leaky windows, and in any area with high humidity.

Health Risks: Exposure to mould can lead to symptoms such as coughing, sneezing, nasal congestion, and in severe cases, respiratory infections. Early detection is crucial for minimizing these risks.

Solution: To effectively remove mould from your home, consider using our Indoor Sanitising Cleaner. This powerful solution is designed to eliminate harmful mould without harsh scrubbing.

What is Lichen?

Lichen is a unique organism that forms through a symbiotic relationship between algae and fungus. You’ll typically find lichen on outdoor surfaces like rocks, wood, and even roofs. Unlike mould, lichen doesn’t require much to survive—just air and sunlight.

How to Identify Lichen:

• Appearance: Lichen is usually pale green and can sit flat on surfaces or appear more textured and ‘hairy’.
• Common Locations: Outdoor surfaces such as rocks, wood, and rooftops.
• Fun Fact: There are over 18,000 species of lichen, and while most are harmless, some, like ‘wolf lichen,’ are poisonous.

Solution: When lichen starts to cover your roof or other hard-to-reach areas, our Wet & Forget Rapid is the perfect tool for easy and effective removal.

What is Algae?

Algae are photosynthetic organisms that thrive in moist, shaded environments. If you notice a greenish tint on your patio, driveway, or pathways, you’re likely dealing with algae. These organisms can appear year-round, especially after rainfall.

How to Identify Algae:

• Appearance: Algae often show up as green spots or a thin film on surfaces.
• Common Locations: Shaded areas of patios, driveways, and pathways.
• Growth Conditions: Prefers moisture-rich environments with limited sunlight.

Solution: Say goodbye to algae without the need for harsh scrubbing or jet-washing by using our Outdoor Mould, Lichen & Algae Remover.

FAQs

What is the difference between mould, lichen, and algae?

Mould is a fungus that grows in damp indoor environments and can be harmful to health. Lichen is a symbiotic organism found on outdoor surfaces, combining algae and fungus. Algae are photosynthetic organisms that grow in moist, shaded areas outdoors.

Can mould, lichen, or algae damage my home?

Yes, mould can cause structural damage and health issues if not addressed. Lichen can degrade outdoor surfaces over time, especially on roofs. Algae can make surfaces slippery and unsightly.

How can I prevent mould, lichen, and algae growth?

Ensure proper ventilation indoors to prevent mould. For lichen and algae, regularly clean and treat outdoor surfaces with appropriate products like Wet & Forget to prevent growth.
