Sodium Hypochlorite

Sodium hypochlorite is one of the most widely used chemicals in exterior cleaning and softwashing. It is highly effective at killing and bleaching organic growth such as algae, mould, lichen and black spot on render, roofs, cladding, paving and natural stone, often removing staining that pressure washing cannot reach. Our sodium hypochlorite range includes Sodium Hypochlorite 15% for contractors who prefer to mix their own solutions, plus the ready formulated Nu-Clear Pro, Nu-Clear Gel Pro and Nu-Clear Fallout Pro, which are designed to make application easier and more consistent on site.

Getting the dilution right is essential. Too weak and the growth will return quickly, too strong and you risk damaging plants, paintwork, metal fittings and some sensitive surfaces. Please read each product description carefully for recommended dilution rates and suitable surfaces, and always test a small area first. A surfactant can help the solution cling and penetrate, while a scent mask makes it more pleasant to work with. Wet and protect surrounding plants and lawns before you start, and rinse thoroughly afterwards. Sodium hypochlorite should never be mixed with acids or ammonia based products. Wear chemical resistant gloves, eye protection and suitable protective clothing throughout. Store containers upright, sealed and out of direct sunlight.
