How to Get Rid of Moss, Mould and Algae Outdoors | Your Guide to Choosing the Right Cleaner

New Zealand weather can be great for the garden, but not so great for your driveway, roof, paths and outdoor entertaining areas!

Damp conditions and shady spots can encourage moss, mould, lichen and algae to take hold, leaving outdoor surfaces looking green, stained and a little worse for wear.

If you've been searching for the best moss and mould remover in NZ, wondering how to clean a mossy driveway or looking for an easier way to tackle outdoor growth, you're in the right place.

At Clorogene, we've got outdoor cleaning solutions to help you get the job done. From our bleach-based Clorodux range to our bleach-free Moss Boss treatments, here's how to choose the right product for your outdoor cleaning jobs.

Moss, Mould, Lichen or Algae: What's Growing Outside Your Home?

Before choosing a moss and mould treatment, it helps to know what you're dealing with.

  • Moss: Often appears as a green, soft growth in damp, shaded areas, including paths, paving and roofs.

  • Mould: Can appear as dark or discoloured patches on outdoor surfaces exposed to moisture.

  • Lichen: Often forms stubborn patches on stone, brickwork, paving and other exposed surfaces.

  • Algae: Can create green, slippery-looking or discoloured areas on damp outdoor surfaces.

Whatever the culprit, unwanted outdoor growth can make your property look tired and create extra maintenance work. Moss and algae can also contribute to slippery surfaces, so take particular care around paths, steps and driveways.

The good news? You have options.

Meet Moss Boss: Your Bleach-Free Outdoor Treatment

Looking for a bleach-free way to tackle outdoor moss, mould, lichen and algae? Meet Moss Boss, our range of slow-release outdoor treatments, proudly made in New Zealand by Clorogene.

Designed to keep working after application, Moss Boss is made for treating unwanted growth on a range of suitable exterior surfaces.

It's available in two formats, so you can choose the one that suits your job.

Option 1: Moss Boss Ready to Use — Attach the Hose and Go

Want to make a big outdoor cleaning job a little less of a mission?

Moss Boss Ready to Use comes in a 2.5L hose-end sprayer. Simply connect it to your garden hose and apply according to the product directions. No measuring or mixing required.

It's designed for treating moss, mould, lichen and algae on suitable outdoor surfaces, including:

  • Driveways and paths

  • Roofs and fences

  • Decks and paving

  • Brick, concrete and stone

  • Other suitable exterior surfaces

The slow-release formula is designed to keep working after application. Leave it on the surface to work as directed, rather than automatically rinsing it away.

Best for: Homeowners who want a convenient, ready-to-use option for outdoor areas without the extra step of measuring and mixing a concentrate.

Option 2: Moss Boss Concentrate — More Cleaning, Less Fuss

Got a large driveway, a number of outdoor areas to treat or a bigger maintenance job on your hands?

Moss Boss Moss & Mould Outdoor Cleaner is a concentrated, bleach-free treatment containing 99 g/L active ingredient. It is designed to kill and control moss, mould, lichen and algae on suitable exterior surfaces.

Unlike the ready-to-use hose-end product, the concentrate is diluted with water according to the level of contamination and intended application.

It is designed for use on a range of suitable outdoor surfaces, including concrete, paving, brick, stone, tiles, wood and other exterior materials.

Best for: Larger outdoor cleaning jobs, repeat treatments and customers who prefer the flexibility of a concentrate.

Clorodux: The Strong One for Outdoor Cleaning

Moss Boss isn't the only option in the Clorogene cleaning cupboard.

Clorodux The Strong One is our bleach-based cleaning option for suitable applications where a bleach cleaner is appropriate.

It can be used to tackle moss and mould on suitable outdoor surfaces, following the product label directions. Clorodux also has other cleaning applications, making it a versatile product to consider for the right job.

The key difference? Moss Boss is bleach-free and designed as a slow-release outdoor treatment, while Clorodux is a bleach-based cleaner.

Your choice will depend on the surface, the type of growth, the product's intended use and your cleaning preferences.

Always check the label before use to ensure the product is suitable for the surface you're treating.

How to Get the Best Results When Treating Moss and Mould

Choosing the right product is only part of the job. How and when you apply it matters, too.

1. Check the weather

For Moss Boss, choose cool, dry conditions and avoid applying if rain is expected within 24 hours. This gives the treatment a better opportunity to remain on the surface and work as intended.

2. Check your surface

Always test an inconspicuous area before the first application, especially on painted, delicate or unusual surfaces. Take extra care around plants, pets and surrounding materials, and follow the label precautions.

3. Apply according to the directions

For Moss Boss Ready to Use, connect the hose-end sprayer and follow the selector and application instructions on the product page and label.

For Moss Boss Concentrate, dilute according to the product directions and the job you're treating. Ensure the affected surface is thoroughly saturated.

For Clorodux, follow its own label directions. Don't assume that the application method for one product is suitable for another.

4. Give the treatment time to work

Moss Boss is designed as a slow-release treatment. Leave it on the surface as directed and don't rinse unless required. Heavily affected areas may need a second application.

Remember, results can vary depending on the surface, the level of growth and the conditions.

5. Help prevent future growth

Damp, shaded areas can be particularly prone to recurring growth. Where practical, improve drainage, remove accumulated debris and encourage sunlight and airflow.

Regular checks can help you spot problem areas before they become a much bigger job.
