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.
Important Notes:

To treat, simply apply a solution and leave to work. Usually a maximum 50% solution will be more than effective on these types of growth.
Sodium Hypochlorite Storage Requirements - Always store this product in a cool dry (below 24 deg C) location that is away from children and animals. Warm and exposed to sunlight conditions will have an adverse reaction to the product as the chlorine will vent naturally.
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.

Great delivery & service would recommend.
Wow just wow. Every year we bring out the power washer to clean our patios. It’s messy and cold and there are always bits that won’t clean. After being told to use this stuff I thought it can’t hurt to use it. Give it a go it can’t be any worse than the power washer. I can now confirm that my slabs look like new with absolutely no effort. I would definitely recommend this company too as I was kept informed of every step of delivery.
I used this on my patio which i have jet washed for the last 3 years since we moved in. I was amazed how well it brought my slabs up as all i did was spray on and then hosed off. They looked great. i then did the same on my concrete driveway and it did the same. So easy to use that i will always use this in the future.
Easy to use, no mess, no scrubbing. The reults are astounding
Tried it 50%/50% with water but this did not remove all black spots. Dabbing with the product undiluted did the trick.
Great product does what it states and at a much better price than branded products.. Instructions could be better and in bigger typeface.
I had previously tried mortar cleaner for my stone stairs and monoblock drive with no luck . The sodium Hypochlorite is amazing. You can watch as it removes the black stains withourt any brushing.
Safety Tip .
If you're cleaning a huge area please use safety glasses and mask to stop inhaling the bleach .
brilliant product
Brilliant! Cleared black algae spots off stone flags when nothing else worked. Don’t go for expensive “patio cleaner “ -use hypochlorite ( carefully )
Firstly, the advice and help from the lady in the office was outstanding.
The product arrived on the date requested..
Patio had a massive infestation of black spots that pressure washer had no effect on.
After using the product as recommended there was a dramatic improvement. I first jet washed to remove mould and dirt. Next day lightly wet patio applied cleaner and left fro two hours. Jet washed again and 95% of black spots had gone. Patio looks almost new. Highly recommend!
