Supplied in the 20L size.

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.

APPLICATIONS

  • Patio Cleaner
  • Moss, Algae Remover
  • Bleaching Agent
  • Water Purification

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.

  34. andy purcell (verified owner) –

    Deep Blue is amazing stuff, and it really does work. Apply properly as per instructions and you will be genuinely rewarded later with clean paths and patios etc. It also discourages weeds on the way. Only given 3 stars as you need to watch the pricing from the Deep Blue Deep Blue Shop which is at May 2018 way above what Costco has it in store. Not unhappy, but Ill check Costco first next time.

  35. Evodevo s. (verified owner) –

    Patio is beautifully free of most and much safer as a result

  36. R Stiegler –

    I applied this about 3 hours ago and its working already Applied to sandstone patio which had morning shade and which had turned very green since Oct. It already looks much less green. Perhaps the weather conditions are perfect too.Im very impressed. I used a 5L pump garden sprayer and it was easy to apply. My only complaint is that the instructions are hard to read had to use a magnifying glass

  37. Andrew RS (verified owner) –

    Relying on previous reviews I purchased Wet And Forget. Just iver2 weeks ago I sprayed it liberally on part of my patio so that I could judge its efficacy. I regret that the area sprayed is insignificantly cleanerbrighter than the area I did not spray.I shall restart the area in question , but at this rate, even assuming it works this time, it is a rather expensive solution please forgive the unintended pun.The old adage if it seems too good to be true, it usually is is proved , at my expense, once again.

  38. Romane Donat –

    This is a fantastic product. We sprayed it in the left side of the patio and after less than 24 hours it already looked great in the 1st photo its not even dry and you can notice the difference. Full patio is now done and look as it should be 100 recommended

  39. RobinX (verified owner) –

    Does what it says on the can.

  40. kat30 –

    Didnt clear patio slabs as well as I expected

  41. Carol G (verified owner) –

    I tried Deep Blue Fluid first, but it needed a lot of heavy brushing after it was put on. But Deep Blue, is just that MAGIC. Just pour it on and hey presto, its magic. Just leave it and it is done and gets better as the days pass. Totally brilliant

  42. LinziC –

    Incredible product. Says what it does on the can. Patio is beautifully free of most and much safer as a result.

  43. Kirk Scott-James –

    Really pleased, great results so far, easy dosing, happy to order again.

  44. LoveLoveCushionsUK –

    Totally Brilliant

  45. I. Anderson (verified owner) –

    Certainly works, or it did for me. Our patio was very dirty with algae and moss and badly needed a spring clean. This would normally mean buckets of bleach and a lot of scrubbing. However, I followed the instructions to the letter on the container and it really worked. Its now three months later and there is still no signs of moss etc. I would really recommend you try it.

  46. M. Savage (verified owner) –

    Very good product

  47. Michaela F –

    Miracle product

  48. stacierenaye –

  49. P. Heuschkel –

    the patio paving slabs are looking much cleaner and fresher after using this product, it took about 2 days to see the effect, but it was easy to use and i am very pleased with my purchase. customer services are excellent, thank you.

  50. Mr Julia Smith (verified owner) –

    Noice works well pleased overall. Pleased overall.

  51. Ms M. F. Walker (verified owner) –

    Wouldn t recommend solid quality, did the job needs improvement.

  52. HBMum –

    The product arrived on time. It was good for getting algae of the fencing but didnt have much success with my decking or patio

  53. Hints (verified owner) –

    I applied the liquid at the weekend on a rather dirty, greenish patio and dark wooden decking and within 4 days the difference is amazing. Particularly on the paving at the shady side of the house the colour of the paving slabs is almost back to what it was when it was new. It is quick and easy to apply I used an ordinary watering can, a broom and for the tricky corners and any verticals, like low walls, I used a brush I would normally use for applying wallpaper paste.Cant wait to see how it will look in a couple of weeks. Job done and the pressure hose is redundant.

  54. Amir Russell –

    Item is fine, however it seemed lost until I followed up. Sorted eventually.

  55. Ms Mia Chapman –

    Okay cleaner with nice quality simple to apply, works okay.

  56. R. F. Jackson –

    This product is very good. It works over time.. the results are amazing. My decking was covered in green algae. I did a patch first to see if this product would work before I got the karcher out … and it works I did add more patio cleanerwater… but you dont have to jet wash …

  62. TheDon (verified owner) –

    Arrived in good time. I sprayed a water feature as soon as the Deep Blue arrived. Within two dull, damp days, the algae was gone. I have now sprayed all my patio and walls. The green went the next day, the black algae is taking longer but, fading every day. Brilliant and so easy.

  75. Stuart Ian Burns –

    After spending a small fortune last year one a new sandstone patio, i was horrified to see it gaining more and more green patches over the winter months, Now the cold weather has finally gone, i have treated the patio and fences and happy to say the green is now gone and a quick presure wash later, it is back to its former glory. I shall be applying another coat to all my fences, patio and flat roofs before autumn comes round.

  76. Miss S Edge (verified owner) –

    I have a brick patio that is a good size. With the very wet weather over the winter the algae, moss and mould have turned a large area green. After reading the reviews I decided to give this a try, I am so glad I did. The direction are very clear and easy to follow. I sprayed all the affected areas and just four days later the whole area was clear. I am totally impressed with this product and highly recommend it.

  77. Jackie foster –

    Excellent choice, strong chlorine cleaner dependable sanitising. Highly recommend.

  85. Burzler Nicole –

    Very strong bleach

  86. Margaret Last –

    Very straightforward to use. just spray on and let it dry in. works pretty well at killing off algae and moss. I used it after power spraying my patio and it seemed to do the trick. Not sure that it would be that effective on its own though, you still need something to remove dirt and thick moss.Deep Blues National Express delivery service is lousey. I live in central Edinburgh and when no one was in to take delivery, they left a note to arrange another day or pick it up at their depot in Livingston 15 miles away. Their only contact was an automated telephone answering service with no option to speak to anyone so I couldnt arange a time or to have it left with a neigbour. I wont use it again, small parcels only from Deep Blue from now on.

  87. Dr Sofia Chandra (verified owner) –

    So pleased, reliable and consistent, easy dosing, and it gives great results, would buy again.

  88. Routard66 (verified owner) –

    Purchased for cleaning the ageing patio. Used 5050 mix on highly soiled areas and 30 on less soiled. Left overnight. Great results the next day.

    Put this on the patio last August a very slight improvement noticed 3 months on husband hasnt noticed and is still talking about power washing next year

  90. DArcy M. (verified owner) –

    It was good for getting algae of the fencing but didnt have …

  91. Mrs Natasha MartinWorth –

    This certainly is magic,you put it on with a sprayer in a fraction of the time it takes to jet wash and it just works away for days,weeks,months even years and it is still working,havent had to reapply yet and it has been 3 years since I did both my patios and paths etc. Be patient as it doesnt do it all at once but gradually works on the terrible algae moss mould etc but eventually they sparkle. Also did a headstone from 1936 which looks absolutely amazing,just like new. Would and have recommended this product many times.Save your energy and your water and use this instead.

  96. Rob Cavill –

    I was a bit sceptical about believing this stuff would do the job, it did take some time, but gradually lm seeing a tremendous difference, the blackgrey dirt patio slabs are now a lovely dark cream colour again…how lovely that is, to just come out and find the cleanest patio its been for a long time…so go ahead and buy this if you need a clean patio to enjoy. I did, then l bought another litre of It to do the other patio slabs which for a path around the house to the gate….wonderful..

  102. Annie24 (verified owner) –

    Bought this a few years ago and was initially very disappointed to say the least. However, now after 3 years the black spot problem I had is virtually non existent and the patio remains cleaner for longer and yearly jetwashes are much much easier. Just jetwashed today and the stones are looking great. Took half the time they usually do. Im a real convert to the product and just about to order some more to keep my patio looking pristine Thank You Deep BlueEarlier reviewI have no idea what magic liquid these other reviewers are writing about It certainly ISNT this Biggest con Ive ever bought. Ive persevered with this product for months as I thought Id give it a fair chance and its expensive and it has made not a jot of difference. Very disappointed with this especially as I made enquiries directly with the company before I bought it about removing Black Spot Algae from Indian Sandstone paving. I used repeatedly as they suggested but see little change after 5 or more months of use.Biggest con. Perhaps Unicorn Urine might work better Im sure Ive seen some on eBayAvoid.

  103. KRayner (verified owner) –

    Powerful cleaner for patio

  108. Mike T –

    I used it for removing black spot from my patio Indian sandstone. It worked brilliantly. I used it undiluted. I used a small brush and applied it specifically to the black spot itself, so you have to be very careful, wear gloves etc and wash down the areas thoroughly afterwards so the solution is neutralised. I left it on for an hour or so before washing off and I tested it on a more concealed area first. It didnt remove every area and some needed a second application but the results were a considerable improvement. I imagine it wont work for every type of paving and you have to be very careful with it and test it first.

  112. michael lawson (verified owner) –

    So pleased with this stuff. Used on my indian sandstone patio which hadnt been cleaned for some years. Reluctant to use pressure washer as the last time some grout was removed. I used Deep Blue about a month ago bought a cheap sprayer and spent about an hour spraying the whole patio. I did this at night when I was sure my pet cat was safely inside and not about to venture out again until the morning as you must leave it to dry for at least 5 hours. Thats all it takes and slowly but surely Im seeing results the slabs are definitely appearing cleaner and brighter. They were a dirty grey before and I can see the original colour coming through. Highly recommend and can see me using this on a regular basis every year.

  113. Norbert Kzms (verified owner) –

    This product is wonderful.I have used it to clean our large patio area,the crazy paving in the front drive as well as removing the grime from all our fencing

  114. Lindsy –

    I had black mouldy spots all over my patio which no amount of pressure washing or other products would get rid of. I bought this in April and used it right away. Im really pleased as nearly all the spots have disappeared, but also the colour of the stone seems to have been enhanced. Because you dilute the chemical it will last for ages. It has taken time but the effects are worth the wait. Ill try and upload photos taken in April 2019 then June and October.

    If you need to remove algae from your fences and gates then Id have no hesitation in recommending this product. It works.However, if youre suffering from white spots on your patio, I think you may find this is not the answer. To give it a really good chance, I used heavily on one badly affected paving slab. I followed the instruction and waited. And waited. And waited.After a lot of waiting, I concluded that this is not going to work. So five stars for the wood, zero stars for the patio.

  137. Dee Chaddah –

    Used one of the two containers to clear black spot black lichen from my patio slabs. I had already pressure washed the patio but the black spots were still left. Mixed up a 5050 solution of this in a cheap hand pumped sprayer and it worked a treat, Only left it it for an hour and then pressure washed it to rinse the solution off and it was fantastic Highly recommend for removing black spot from patios.
