High Strength Liquid Chlorine: Sodium Hypochlorite Patio Cleaner Solution

This is a fresh, high quality product supplied by the UK’s largest chemical manufacturer. Every batch is certified for proper concentration, so you are not getting a diluted imitation, and it arrives in tough courier drums that hold up far better against leaks and knocks in transit or storage than the flimsy clear plastic drums sold by others.

Orders go out on a next day delivery service, so you can get started on the job without delay.

For clearing moss, algae and weeds from drives, patios, walls, fences and brickwork, Sodium Hypochlorite High Strength gives you a fast and lasting fix. It ranks as the world’s leading patio cleaner and turns up, diluted, inside many other cleaning products on the market. Because our Sodium Hypochlorite Solution comes at a relatively high concentration, you shouldn’t need repeat treatments: a single application leaves surfaces clean and free of moss right away.

Sodium hypochlorite is a chemical compound with the formula NaClO, made up of a sodium cation (Na+) and a hypochlorite anion (ClO⁻); it can also be thought of as the sodium salt of hypochlorous acid. Once dissolved in water it’s generally known as bleach or liquid bleach. Chemically and practically, sodium hypochlorite is distinct from chlorine, and it’s widely used both as a disinfectant and as a bleaching agent.

Guidance for using Sodium Hypochlorite Patio Cleaner & Moss Remover

SUPER FAST : MOSS, ALGAE, LICHEN, WEEDS & MOULD – REMOVER!

Sodium Hypochlorite Patio Cleaners are used for more stubborn stains as you need the EXTRA strength solution, which is stronger than standard solutions and may be diluted with up to 6 parts water and 1 part Sodium Hypochlorite High Strength.

Applied as a moss, algae, lichen, weed and mould remover, this solution starts showing results within minutes of being left on the surface. It takes the effort out of cleaning your drive, block paving, fences, walls, brickwork, stonework, paths, patio decking, gravelled areas and even roofs.

Use neat to shift old and stubborn growth, or dilute it for routine maintenance. Even diluted, Sodium Hypochlorite still outperforms the rest* and can treat up to 10m² per litre. Give the outside of your home a Spring refresh that turns heads on the street.

Important Notes:

– This product is not for use on lawns, flowerbeds, vegetable plots or around trees and shrubs.

– Keep people and pets away from the treated area for 2 days.

In general the following precautions should be taken:

  • When using chemicals, protective clothing such as gloves, goggles, boots and overalls should be worn.
  • Adequate ventilation is required when using chemicals in confined spaces.
  • When using flammable materials; cigarettes, naked flames and other sources of ignition should be carefully controlled.
  • When diluting acids, always add acid to water and not water to acid.
  • Any clothing that is contaminated with chemicals should be disposed of safely.
  • When using any chemicals, care must be taken not to damage, contaminate or stain any adjoining materials, landscaping or finishes.
  • Care must be taken to protect personnel operating in the area of the cleaning from any injury or hazard created by the cleaning. The appropriate First Aid must be available.
  • Before undertaking any cleaning operation, a trial should be carried out on a small, preferably inconspicuous area, to determine the effect of the chemicals before treating a large area.
TYPES OF ORGANIC GROWTH ON SHADED AREAS
  1. Algae – appears as a green film or powdery coating on paving stones and stonework.
  2. Lichen – often grows on timber structures and paving stones, ranging in colour from orange to silver with a scruffy appearance.
  3. Moss – turns up on all kinds of surfaces and can form very dense clumps of growth.

To treat these, apply the solution and let it work. A maximum 50% solution is usually more than enough to deal with this kind of growth.

Weed Control using Sodium Hypochlorite Patio Cleaner

There’s no truly weed-free surface: once organic material starts building up, it’s only a matter of time before weeds and other plants take hold. On paving, weeds typically establish themselves in the sand joints, using the sand as their base. When you’re using sodium hypochlorite for weed control, give those joints extra attention for the best result. It’s one of the most effective patio cleaners around because, alongside cleaning, it also controls weeds and slows re-growth for weeks or even months afterwards.

Guidance for using Sodium Hypochlorite – Pool Chlorine

Sodium Hypochlorite High Strength 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.

  28. Greg Ashley –

    This stuff is remarkable For years Id struggled with a patio that goes blackgreen and slimy and needed scrubbing at least twice a year, even with jet washing. Id tried every type of patio cleaner I could find and nothing worked well or lasted. A friend recommended this, so I gave it a try. The immediate results were good but not overwhelming but over the following weeksmonths, my patio continued to brighten up and has stayed incredibly clean ever since… and that was over 2 years ago Ill likely give it another spray this winter because there are slight signs of darkening but this is no longer a daunting or backbreaking task. I diluted it a bit further and sprayed it on my motorhome roof, which is also still gleaming white after 2 years without a proper wash. Anyone with a camper or caravan will know how remarkable that is. Im so impressed and would definitely recommend Deep Blue.

  29. Martina Brill –

    Superb cleaned like magic

  30. mary collins (verified owner) –

    it is absolutely FANTASTIC. Its the first thing I use in my …

  31. Steven D. –

    I bought my first Patio Macic from Deep Blue, and was amazed how the product cleaned my algae in no time at all. This recent purchase is to keep in stock for the future.I have recommended it to my friends at my bowling club, and they too are very happy with the results.Very well done. Thank you Mr. R.W.E. Cherry.

  32. J Browne (verified owner) –

    Patio cleaner worked well on my paving block. However l did do a little experiment as wellMy house brickwork has salt stains on the brickwork this is like white chalk marks. Putting some of this cleaner into a small bucket then with a good size paint brush gently apply to the salted brickwork marks. I found this works a treat l just left to dry out. Next day the salt marks had been completely removed. I will definitely use this again should the need arise.

  33. Debbie Murray –

    Cleans algae off the patio and protects from further discolouration. I used a sprayer to apply, as per instructions.

    Deep Blue Green Mould and Algae Killer…Good product needs to be left to work on the stains or use a stiff brush and plenty of water and it gets good results. Just follow what it says on the label. Enjoy.

  42. linamalie (verified owner) –

    For the last two years my beautiful northfacing patio was turning grey and black with streaky mould. Using a bleach kitchen product hardly touched it even with a tremendous amount of scrubbing. Researched and read the reviews for this and decided to give it a go. Used a dilution of 6 parts water to 1 part SH. Used a hand sprayer to apply. You virtually see the mould, algae, moss, lichen, black little spots disappear in a matter of minutes. It has resored my patio to new. A fraction of the price of similar branded products. 10 10

  43. Skoobz –

    Our new patio had gone green in places over the winter just used watering can to apply and completed removed noticed a difference the next day will order moreVery pleased with product

  44. Rush Radio –

    I wanted it to remove rust spots on concrete patio tiles. It had no effect whatsoever but it did a fairly good job on algae and black spots.

  48. Krzysztof –

    Applied this a week ago to block paving at front and patio at rear. Didnt work overnight but had bit of rain and starting to notice the difference. Love to know how this works my patio is now spotless And the block paving is looking Cleaner each day. No more steam hose for me love this product. Would definitely recommend this well worth money.

  49. Chris Delgado (verified owner) –

    This stuff works. My patio had been jet washed several times over the years but black spots remained. I diluted this equal parts with water and sprayed it on. It was incredible to watch the black mould spots that have made my slabs look grey and shabby for years disappear before my eyes in 1 to 2 minutes. The greyness and black spots vanished. My slabs are a buff colour again. I was shocked and delighted how effective and quick it was. Do be careful though. This stuff bleached my trousers and hurt when splashed on my skin. Be safe.

  57. Mr. A. J. Dandy –

    Originally purchased approx 1 year ago, used on my block paving and patio slabs, initially used a strong dose to start with and I am more than happy with the progressing results. Follow the instructions on the tub, Success wont happen overnight but within a few weeks you will see a difference and it will keep on working through the months. I gave it a topup after six months. Im now using the 2nd tub and the dilution rate works well. My block paving was very dark and had a white spot lichen, it is now back to a pink colour and virtually lichen free with no power wash and no scrubbing. I saved quite a bit of money and enjoyed doing it myself. Would highly recommend.

    Nothing Better for Patios and Drives

  75. laurence gillespie –

    fantastic product for killing removing green from concrete, patios, paths, timber etc. Easy effortless to use and incredibly effective, leaving a clean as new surface within days. I tried so many products that claimed to do all of the above and they were all next to useless. This seems expensive but is incredibly good value and well worth every penny. no scrubbing or elbow grease just dilute it and pour it into the surface with a watering can and watch the transition over the next few days.

  76. Mrs David White (verified owner) –

    Good purchase

  77. Amir (verified owner) –

    Does remove algae and moss. I was hesitating to buy this product, I needed something really good to take care of my 5 year neglected patio. Originally wanted to use jayes liquid or caustic soda, but decided to go for Deep Blue as it promised to be biodegradable. Didnt want to risk life of my newly settled garden plants that grows on verge of the patio. No results after coating, but 48 hours later all green algae are gone, the only remnant are darker patches on the slabs. How they would go away after 7 days as promised on the label. Otherwise it will be scrubbing fun with some heavy duty chemicals. Make sure there is no rain within 7 hours of the coating.

  78. Euan (verified owner) –

    Purchased after we finished out maintenance on our yorkshire stone patio, having researched into various ideas, and spending time , money and effort on re grouting, and cleaning, some on the slabs are 5thick so we needed too make sure we get it right the first time. Purchased this and it was so easy too apply, but as I only applied in in May 2015, I cant comment on the durability, I will update my review after the winter of 2015 hopefully there will be no moss, or algae too report and it will be a positive comment too be added

    We have a shady courtyard garden in central London and the brick pathways can get very green and slippery with algae growth. I used Deep Blue at a 41 concenrate. The results over the next few days were quite amazing. All the growth onbetween the bricks was killed off and the product kept on working over time. This initial use was over 8 weeks ago now and I still have clean brickwork. Its very easily applied with a watering can and does no damage to the old reclaimed London brick.

  98. Marie P. –

    Order arrived earlier than thought, product excellent does what it says, no fuss or bother, woulddefinitely recommend, used on decking and patio both came up looking great.

  101. Gillian Anderson (verified owner) –

    I was really hoping this would be all it claims to be, but sadly it doesnt look promising. Ive used it in 3 different areas over a couple of months they claim it can take several months to show full results, the only thing that seems to happen is that the moss turns brown. Dont know if it will eventually die back completely or not. As for removing lychen or anything for that matter, it has been singularly disappointing. Neither brick patio nor paving slabs for my path have shown any improvement since treatment. Some slabs Ive treated twice still nothing. Am currently pondering whether to keep it as a moss killer or to return for a refund. There must be cheaper moss killers out there thoughUpdate Dec 2017 lychen algae have indeed been removed, but has taken several applications over many months a couple of seasons. So patience is likely to be rewarded, especially for areas where pressure washing is either unsuitable or simply ineffective. Upgraded to 4 stars from 2.

  102. Matthew TylerHowells (verified owner) –

    I waited and waited for a dry day but once it came I treated the whole of our patio. The product said it would take time to work but within a few days all the green had gone. I even have half the product left for repeat applications when needed. Highly recommend.

    Patio Macic

  122. Gemma Prince –

    Used this to remove blackspot from the rear patio. Power washed the whole area first to get rid of the last years grime, then sprayed the Sodium Hypochlorite at a 5050 water ratio on approx 3sq yards at a time, left it for 30 min and washed off, excellent result. Then repeated over whole patio at similar sized areas and could not fault it. Have only used about 8 of the 20 litres that I ordered so will be ready for next year, if the blackspot returnsTBH I think I could have done the whole patio in one go and not waited the 30 min however the problem of continually shifting garden furniture pots and plants made that a tad impractical.Dont have a before after image but this shows how clean it is, almost like new

  123. Cristiano vaianella (verified owner) –

    Very good value for the money . My brother in law told us how good this was .Have used it on the patioit looks great now.

    Used this for patio which I usually power wash. This is 99 better than power washing and not hard work. Have ordered more for next year. The difference is like night and day. Back to original colour. We used to power wash 2 times a year but wont have to this now

  125. Ross Reed (verified owner) –

    Top product, takes the hard work ot of cleaning my patio.

  130. BevD –

    This product is totally amazing. It does exactly what it says on the tin My drive and patio have never been this clean. We used to spend hours jetwashing every year, not no more. I would recommend this product to anyone.

  131. Rebecca Bailey (verified owner) –

    Not bad cleaner with consistent performance works as described, works okay.

  132. jeane easterbrook (verified owner) –

    It does what it professes to do.

  133. T.A.B. G. –

    This stuff is amazing I must admit to being a little sceptical about well this would work but I neednt have worried. It exceeded all of my expectations I simply sprayed the liquid all over my blockpaved patio and driveway, and even on the bits of my roof that I could reach. The results were remarkable to say the least. Within days the moss had turned brown, then black, then it was just washed away by a couple of heavy rain showers like the blurb said, I just had to wet and forget. Would highly recommend.

  134. Walbs –

    Very sceptical about whether anything would actually clean the green from my patio tiles. Just one application using half the tub and still looks brilliantly clean 8weeks later. Definitely worth every penny and recommend to anyone with green slimy paths.

  135. Zoey (verified owner) –

    Strong

  136. Vittorio Beggi –

    Speedy delivery and easy to use. I had quite a lot of moss growing between the patio flags and within 2 days of spraying it turned yellow and died. It also removed the green staining on my concrete fence bases which no other cleaner has done before.

  137. Gurpreet G. Kelly (verified owner) –

    Easy to install works well pleased overall. Would buy again.

  138. Freeman North East (verified owner) –

  139. Barbara Bentley –

    … used this the begining ofthe year patio still looking good

  140. MR E KERINS (verified owner) –

    This stuff is BRILLIANT BUT you MUST wait for it to work. The first time I used it, I thought it was useless. Some months later I noticed that ALL the lichen that was staining my patio and paths and which even the most powerful Karcher washer couldnt shift had completely disappeared Sprinkle on with a watering can and wait. There is nothing to match this product, its simply fantastic, but you just have to be patient.

  141. mnb123 –

    This product is amazing it really does work. I was always having to remove moss and power wash the drive and patio but not anymore. You need to buy a sprayer we have a large drive, path and patio and 5 litres covers everything. Sprayed 6 months ago and no moss has come through yet. All areas also look very clean.

  142. Ms Cian Douglas –

    So pleased, good value overall, easy dosing, and it gives great results, no issues so far.

  143. Claudia Megdad –

    Amazing effect on our patio. 18 months after original application and patio still very clean.

  144. Jay90hayden –

    Cleaned patio and killed moss on drive easily on 1 application. Keeps on working for months. Would definitely buy again.

  145. Cat Gordon –

    Done a good job of patio

  146. LJB –

    Used on patio. Was quite worried as it went very brown. But within 2 days it started to brighten and now all algae gone and it is now quite bright and clean. Bought from Deep Blue as was good price. Would definitely buy and use again.

  147. Linda Leeming –

    It really works but be patient

  148. Stelios –

    Love it. Used it on patio, caravan roof and conservatory roof. Cleans the patio wonderfully, without stripping the surface, like my pressure washer did. Brilliant on the caravan roof, which had the algae of 7 summers and winters on it. Hard to clean area, as the roof is wide and long and hard to access. Sprayed all over with Wet and Forget then forgot about it. a few weeks later and the roof was clean as new. And we can now see out of the conservatory roof. I would recommend to anyone who has mucky, hard to reach areas and cant get anyone else to do the hard work

  149. dashingtons (verified owner) –

    Absolutely brilliant product you just have to wait for the results.

    Very easy to use. Good result on our patio and also used on a very green parasol and fence. May need a 2nd treatment to get it all clear.

  152. michael gibney (verified owner) –

    This product is the best stuff Ive ever used on my patio and drive.Both are block paved. Bricks came up like new.5050 mix with water, spray it on, leave it over night, and the results are amazing.On the patio, I power washed first, and then sprayed the Sodium Hypochlorite. The bricks changed before my eyes.The drive, I sprayed first, and then power washed. Both results were fantastic.

  159. Sri Semmelrock –

    Have so far used on a fairly new sandstone patio which was already going green in places that sit in shade and it worked in a couple of days. Also some teak furniture in the same location, back of the house, and some concrete steps. Ill get busy with other areas once the weather improves. Really impressed.

  160. Gail Rowe (verified owner) –

    If I could give this more stars, I would. Ive been using this product now for about 7 years …. it is absolutely FANTASTIC. Its the first thing I use in my garden to start my spring cleaning. I use it on my pressed concrete drives, my garage doors, my indian sandstone patio, my rattanglass top garden furniture, the outside of my glass house, my railway sleeper retaining walls and steps and just about anything that get covered in the green slippy stuff over the winter months it seems to me that the very mildwet autumnwinters are doing us no favours and just creating slippery hazards everywhere in the garden. Its now 27.03.17 and my gardenfurniture and everything that was treated a week ago is now ALL CLEAR using the 15 ratio. My sprayer is round my sisters at the moment, so I just used a watering can to administer the solution. Works a treat. Im not sure why those with low ratings have not had success with this product as it really does do what it says on the tin …. theyre either making the solution too weak or perhaps not buying the genuine item …… in all the years Ive bought it, its worked first time every time with GREAT SUCCESS …. I would point out that this product is NOT A GENERAL CLEANER, ie it doesnt remove general dirt … please read the product description before buying to ensure that its the right product for your requirements those people that say bleach works just as well clearly dont have the slippery stuff to get rid of. ………….. next for me will be the fence and wood preservative for all the wood that has been treated a job for Easter methinks.

    Item promptly delivered. Now Ill have to wait and see Applied 5 litres as directed in suitable conditions on a rather grubby patio. Will now wait for the magic to happen, but after 24 hours too early to tell. Not convinced at this point, but hoping to be proved wrong,

  169. Mrs Dawn Jenkins (verified owner) –

    Was recommended this to clean up patio flags, had read mixed reviews but decided to give it a go. It worked really well, every day they got a little cleaner. Within a week they were good as new

  170. RB3535 (verified owner) –

    My 2 yaer old Yorkshire stone patio was looking dreadful and dark green. I was contemplating buying a power washer as this was obviously going to be an ongoing problem. I didnt really expect much from this product to be honest but decided to give it a go. I brushed the patio first and then sprayed it with the product. 1 part product to 4 water. It says it works within 4 to 5 days . Well within 2 hours 90 of the staining and algae was completely gone. I paid 70 last year to get it jet washed so this is a bargain, and this time it hasnt damaged the black pointing. I will seal it on the next dry day. Im very pleased..understatement
