Sodium Hypochlorite patio cleaner is the quick and easy long term solution to cleaning and removing moss, algae and weeds from your drive, patio, walls, fences and brickwork. Sodium Hypochlorite patio cleaner is the worldwide number one product to use, and is commonly found in dilution in various other versions of patio cleaners. The Sodium Hypochlorite Solution we have available is highly concentrated and will remove the need for numerous applications, one treatment will provide a clean and moss free surface immediately.
Sodium hypochlorite patio cleaner is a chemical compound with the formula NaClO. It is composed of a sodium cation (Na+) and a hypochlorite anion (ClO−); it may also be viewed as the sodium salt of hypochlorous acid. When dissolved in water it is commonly known as bleach or liquid bleach. Sodium hypochlorite is practically and chemically distinct from chlorine. Sodium hypochlorite is frequently used as a disinfectant or a bleaching agent.
Sodium Hypochlorite Patio Cleaners are used for more stubborn stains as you need the EXTRA strength solution, which is 50% stronger than the heavy duty solution and may be diluted with up to 6 parts water and 1 part Sodium Hypochlorite 15%.
To use Sodium Hypochlorite Patio Cleaner as a Moss, Algae, Lichen, Weeds and Mould remover you can apply the solution and leave and within minutes you will begin to see results. Take the hard work out of cleaning your drive, block paving, fences, walls, brick work, stonework, paths, patios decking, gravelled areas and even roofs.
Use neat to shift old and stubborn growth or dilute for routine maintenance. Even when diluted Sodium Hypochlorite still outperforms the rest* and can treat up to 10m² per litre. Spruce up the grounds around your home this Spring and make your home the envy of your neighbours.

Unfortunately there is no such thing as a weed-free surface. If organic material is allowed to accumulate on a surface it will only be a matter of time before weeds and other plants begin to grow. Weeds grow on paving through the sand joints by using the sand as a base to begin. When using the sodium hypochlorite as a solution for weed control, pay additional care to the joints to ensure success. Sodium Hypochlorite Solution is regarded as one of the best patio cleaners because it will also control weeds and will deter re-colonisation for a period of weeks, even months.
Sodium Hypochlorite 15% is used for the routine control of bacteria and algae in swimming pools. For effective treatment ensure that the chlorine levels of the water are a level of 2-3mg/l (ppm). The levels must be maintained above 1.5mg/l (ppm) as a minimum. Once the chlorine has been applied the pH of the water must be adjusted to between 7.2 and 7.6 before use. We recommend these levels are routinely checked by using a pool water testing kit. When applying the Chlorine add at the point of best mixing, i.e. the water inlets and leave the filter running to ensure even distribution. All personal protective equipment must be used when handling this product.

I have used several stone and patio cleaners in the past, this is by far the best product on the market, used in a 50-50 mix it gets rid of the black spots that stone flags pick up from surrounding trees, in a 5-1 mix it kills moss in a few days and brings the original colour back to all patio surfaces.
Best product I have ever used.
My patio is like new. Put the power washer in storage and use this cleaner with care and it can stay in storage.
This product is incredibly good.Keeps our drive clear of weeds and moss for months. I would thoroughly recommend this for anyone who wants to keep their drive in good condition.
This is the best product you can buy if you really need the job to be done!!! Other products are far less efficient. Will buy it again
Magic stuff! Bought it to deal with lots of black spots (lichen) on patio paving slabs. These had refused to budge with power washing and all other products I'd tried. Eventually I came across a couple of Youtube videos by guys who make their living using this stuff to professionally clean their customers' patios. I was so impressed that I bought some, followed the instructions in the videos and, I'm pleased to say, achieved very similar results. The patio now looks almost as good as new. Very satisfying!
Used to clean my patio which was covered in years worth of black spots. Applied with a brush to the patio slabs and the black spots disappeared. A few areas that were really bad needed an extra treatment. Patio now looks like new!
Have successfully used this product two years in a row. It has been easy to apply with great results on my drive sets.
Great for cleaning patios, delighted with the results. Great service from Chemiphase, would highly recommend.
Good product for cleaning badly stained patio but wear old clothes & shoes .
