1. What is sodium hypochlorite?

Sodium hypochlorite (commonly known as hypo) is a powerful oxidising agent, commonly known as liquid bleach. It’s widely used in exterior cleaning for removing algae, moss, lichen, mould, and organic staining on driveways, patios, roofs, and render. When diluted and used correctly, it’s one of the most effective surface cleaners available.

2. Is sodium hypochlorite cost-effective for exterior cleaning?

Yes—sodium hypochlorite is one of the most cost-effective solutions for exterior cleaning due to:

• Low price per litre

• High dilution ratio (often mixed 4:1 or more with water)

• Fast-acting results, reducing labour and time

• Large coverage area per use

One 25L container can clean hundreds of square metres, making it significantly cheaper than pressure washing or many off-the-shelf patio cleaners.

3. What surfaces can hypo clean?

It’s highly effective on:

• Block paving

• Concrete

• Natural stone (non calcite stones only)

• Garden walls and render

• Decking (with care and instruction)

It’s often used in soft washing systems to clean without aggressive pressure.

4. How do you use it safely and effectively?

1. Dilute correctly depending on the level of contamination (commonly 3:1 or 5:1 with water).

2. Apply with low-pressure sprayer, avoiding direct contact with plants.

3. Allow 15–30 minutes dwell time, do not let it dry on the surface.

4. Rinse thoroughly with clean water.

5. Protect plants and pets during application—cover foliage and rinse before and after.

5. Where can I buy high-quality sodium hypochlorite?

You can purchase premium hypo in 25L sizes directly from Cleaning & Sealing. Their professional-grade solution is trusted by exterior cleaning companies across the UK.
