- A demonstration on just how few tools are required to do a decent job cleaning a concrete drive way using SH - HYPO - No power washer or expensive tools required.
ALWAYS EXERCISE EXTREME CAUTION WHEN USING HYPO AND NEVER MIX WITH OTHER CHEMICALS - IF YOU ARE UN-SURE DON'T DO IT!
I’m a 57 year old woman and I used sodium hypo. I was dressed like something for breaking bad in my PPE which cost 12 quid for the two of us. 1:4 ratio. Less noise, less damage, less water. Quite easy. Worked with husband. Used snow shovel to protect lawn. Strict caution though on using as it burns and damages. It’s brilliant stuff no more need for blokes wreaking the patio or drive. Made liquid up in a bucket and brushed in. Quite therapeutic.
Breaking Bad is a classic.
Great Video. Shows how easy it can be. Out of all my videos the time I went with my brother to do a Softwash job is the most watched. 🤷♂️
I love your effort! increase your SH to 5:1 and you won't have to brush the surface and it will rinse pretty clean. Im Devin I'm the owner of WashWorks Power Washing in Foxborough, MA. USA. I love the UK and Jeremy Clarkson.
and let it dwell on the surface for 10-15 minutes
Jeremy Clarkson.... Possibly the best motoring Journalist........... EVER. 🤣😜
Fantastic job well done 👍👍👍
Thank you for your video! 🙂
Great vid Darren.
Good Info , thanks
Excellent explanation. Thanks.
You are welcome!
Well put together video, unlike some others that faff on for ages. Just so happens that I used this stuff last year on block driveway using the exact same method. Came up a treat. Only difference was I used a pressure washer to rinse it down afterwards and "walk" the crap into an area for disposal. One interesting thing I learnt from this video was that once it had reached its expiry date it only degrades to 10% and is still usable. That's great news as I have around ten litres left over from last year. Thanks. Hope that sneeze wasn't covid!
LMAO.... That sneeze is 100% Old School.. I got trapped in SE Asia when they invented COVID and to this day I am still here. 🤣
Hi Darren, Thank you very much for the first-class info, have been a great help. Can you advise on a start-up water-fed pole system for a one-man operation?
Talk to Adam at the Cleaning Warehouse in Wolverhampton -
A great video and as always showing that money isn't spent on silly equipment
Wow really.....not. You cant use hypo near ponds streams waterways and other delicate areas so we spent our money on a silly steam washer...@~+*
@@stuartrussell891 no one forced you to spend loads on equipment and we are not all tree huggers and snowflakes
@@AW-Services it has nothing to do with tree hugging man. For most places it's the law and you can be fined huge amounts
That does a VERY good job mate
Yes and a lot less hassle than power washing too I find.
@@Darren-Green
Hello does these chemical harm animals?
@@Smith6265 It can yes - hence all precautions must be followed.
i had a bad patio, algae, lychen( however you spell it) used roughly 3-1 mix and left it for an hour. came out perfect, only a few bits i had to go over with a brush and another mix.
Glad it worked. 20 - 30 mins is long enough as solution becomes inactive after a while. But you got a result and that's all that matters.
Brilliant, very helpful that
Thank you Kelvin
Good video, ... I've used Sodium Hypochlorite for years cleaning stone and concrete driveways with oil stains, works wonders, .. Even cleaned with Sodium Hydroxide (drain cleaner), you can't beat chemical cleaning, forget all the crap in the shops, they are all to diluted to do a proper job .... My advice is if you need to wear protective gear then it will work! ;-)
Can we clean our water tanks with sodium hypochlorite liquor, please advise.
Yes you can
Yes but a very weak dilution, the make sure to flush at least twice with pure water.
Hi just starting up on my own came across youe post spot on what boots are those you are wearing cheers
How to clean that lichen over there? seems to be a dark patch make it perfect clean . loved your DIY .lots of ❤️❤️❤️❤️❤️❤️ From India
Bloody hell ! Amazing !
Used this myself its great stuff...
It sure is.
thanks
Powerful old stuff that.
Great thanks very much
You're welcome!
Appearantly over here i can only get natrium hypochlorite can i use that aswell?
Helps alot
Glad to be of help
Brilliant Darren. I will be taking on this task next weekend, the solution arrived last week. Your video was comprehensive and easy to follow, actually made the task a lot simpler than i thought it would so thank you. One question how long would you suggest leaving the solution on for please?
A few minutes - literally 4 or 5 mins is all it should take - remember though better to do 2 applications than try to overpower it in one.
@@Darren-Green Many thanks for your swift response Darren. I'm rather excited!!!! Cant wait to see the finished result. I will be cleaning my 85 year old father's patio. He adores sitting out in the sun for hours on end so his wonderful daughter (lol) will be making the experience a much nicer one. I planted some wonderful plants, have already moved them onto the lawn, Ive painted his fence and shed so this is the last bit to do before the summer (that I hope we get)!!!! Thanks again
@@Darren-Green Will do do applications, great tip
@@Hope-uq1vn Thanks Hope
Bless you, sounds like an algergy to me...
Great video. Can it hurt flower beds or lawns if the pavement is close to them? TIA
Yes it can burn the plants. The trick is to literally soak the edges, grass plants etc to saturation with water prior to starting. That way the plants literally stop drinking for a while and as the peroxide is inactive after about 15 mins it prevents the plants consuming the harmful parts.
This was an interesting video and informative talk at the end. Did you wear a face mask when using this stuff. Looking to clean roof tiles, path and patio.
All the best from Old Kilpatrick, near Glasgow
Cool video. Where do you get the cleaning stuff from?
From a farm shop
@@Darren-Green thanks for you need licence to use it and how much do you need for a standard watering can?
Good Info !! Thanks for Posting .
PS - What happens if accidentely mixed with Biocide ???
If I recall, some type of nasty mustard gas type stuff
hi great video does this impact grass surrounding plants trees etc
Yes. Be sure to water all immediately surrounding grass to saturation point prior to treatment. Proceed with cleaning. The saturated grass won't absorb any more water or solution. The solution will be ineffective after 30 minutes.
excellent suggestion. Although this is easy solution but everyone seems to try to sell pressure washer. is it due to Hypo being unsafe or they just want to sell an expensive pressure washer?
Of course they want to sell you an expensive power washer, that's their job! :)
Yes Hypo can be dangerous if you are not cautious and follow the instructions properly.
I have a poured concrete pathway (not pavers as your video), i have sealed the concrete so it doesn’t dust. Will the hypo damage the concrete sealer i applied?
Will this remove old oil stains from a block paving drive? Tried most products nothing really works elbow grease from b&m faded it slightly.
No it wont remove oil stains. Sorry.
Will this remove efflorescence off patio slabs? If not, do you recommend anything for it? Every slab in my garden is stained
Eff requires hydrochloride acid - be very careful with it
How much do you charge per sqm for cleaning drives mate
£10 here in the midlands.
Hi there! Great job. Can I use a soft wash surfactant on a tarmac tennis court? Can you please recommend a product? Thank you!
You can but I would use it in weaker dilutions. The key to tarmac is a stiff brush and elbow grease. Always best to clean tarmac after a hot couple of days in summer when the moss is dried out and brushes off more easily.
Okay but what happens when you put grass into the situation does it kill it? I imagine so a jet wash wont
Like anything, if used incorrectly it will do damage. If you are using it around grass or foliage pre soak the foliage thoroughly, this will prevent the grasses from soaking up more liquid, they wont absorb more than they can handle. Then apply Hypo, hypo will only remain active for about 20 mins before breaking down far enough that it can be rinsed off. Any real power washer (not the Karchers or Black and Deckers you use to wash the car type but commercial grade power washers can destroy the grass a hell of a lot faster than Hypo can. It's all about correct usage regardless of the tool.
Great name, can you write down what he just said at the start?
Not sure what you mean 'Darren the window cleaner, Green Pro Clean Nottingham and Derby' ??? That's what I said at the start.
@@Darren-Green its big, just that, doubles down as a slogan
@@Darren-Green and asked to write down because i didnt understand, i am not english, thanks for the answer btw
Can too strong a mixture of sodium hypochlorite damage paving? In my case Indian sandstone - I been mixing 1 part 15% with 4 parts sometimes 3 parts water.
and has it been damaged?
If you are diluting it that much you could just use supermarket bleach which is often available in concentrations up to around 5%. More convenient for the DIY'er who doesn't want to buy a massive quantity for a once a year job.
Typically supermarket brands are 3.25% and yes will work. In the US many softwash companies go straight for Colorox.
Buy swimming pool chlorine, available at most big box home material stores.
@Darren-Green I can assure u no soft wash pros/anyone really use clorox in the US
Would this work in a spray bottle on a crematorium slab? I have hypo in shed.
Theoretically it should. I once had a conversation with a headstone company and they told me how they do it and there's a amount of permission you need from cemetery or church etc. Not as straight forward as you may think.
when you have small weeds in the bloc paving , is it best to remove weed first , or would this instantly kill weeds without having to weed manually , how would you approach that situation , my thanks in advance
This will kill the leaves but not often the root so best to weed first in my opinion.
Green Pro Clean Ltd is it best to mix a professional weed killer in it as well, doing both jobs at once?
Plus adding the surfactant (fairy liquid) will help both the bleach and the weed killer?
Rock salt
Will the solution kill grass? I have grass on both side of pathway.
Soak the grass well, before and after.
As long as the grass is thoroughly soaked (clean water) prior to application of Hypo it will be fine as long as you also soak the grass again immediately after application.
could this be used on galvanise fire escapes?
Hypo is highly corrosive, so be sure to rinse very thoroughly and do not let the hypo dry on the surface. Keep misting the surface if there is a danger of drying.
Yes but as above do not allow to dry and be sure your rinse is 💯%
What soap can you use with hypo Darren
Really anything but the thicker the better as it helps adhere to the surface more.
I've got a tub of the stuff, going to do my drive/garden soon, how long do I leave it/how many times do I need to wash off the chemical before my dogs can go on it safely?
Put it on leave 10 mins, rub with soft brush and rinse 5 mins after brushing
Can I spray Hypochlorite with the detergent hose in the pressure washer? I have a petrol pressure washer that has a little sucking hose to feed from a bucket, the PW also has a sprinkle tip to work as a normal hose.
You can BUT the hypo is harsh on the internals of your machine so be sure to run a good 20 or 30 liters of clean water through it AS SOON as you are done.
Spray through a 2 gallon pump sprayer. You will be able to control your overspray somewhat better. Use a course spray. The wind will carry a fine spray where you don’t need or don’t want. And he is correct, wet doesn’t all foliage in the area before spraying and after. Also basic Personal Protective Equipment is more than a good idea.
Can this be used on brick walls as well?
Yes, I have used on brick without issue,.
@@Darren-Green Thank you, any advice on not having it splash everywhere?
Is it safe for charcoal coloured pavers?
Honestly, test patch on discrete area first
Can this be used to kill moss on house brick?
Yes. But you would be better to use a BaC 50 based biocide.
@@Darren-Green should the same precautions be used with bac 50? Can't find much information about it, and what dilution ratio would you recommend for moss on brick work. Thanks
Did you wear a mask or just eye protection please?
I just use Tide detergent
In the United States sodium hypochlorite goes by the name of bleach and you can buy it at any grocery store by the gallon.
Yeah.... Close but not quite. Sodium Hypochlorite is the ACTIVE INGREDIENT in bleach.... Not actually bleach itself. Most bleach has a SH content between 0.75 and 3.0% dependant on intended usage.
Will hypo remove latex paint from concrete?
I do not think so - you need to find the brand of paint, then in it's info sheet (manufacturers website) it will give you removal agent options.
@dee 1987 sure.... give me £5k pllus for the machine and I will use it
How you dilute
spit in it
does it work on block paving?
Yes mate
Looks the business
Thanks
Does it hurt grass?
yes, it can, always soak the grass thoroughly prior to using it near the grass this will help prevent damage.
It does not matter how much you wet the grass. It will kill the roots.
Did he say in the intro that if you're watching this you shouldn't bother? Lol
Nope. He (I) said if youre asking me instead of Google you shouldn't bother. Please quote verbatim amd not just three words from a sentence out of context in efforts to exacerbate an inflammatory post mate. 👍🏻
@@Darren-Green I couldn't hear what you said so how am I supposed to quote you verbatim? Absolute fucking moron.
I think your rude reply suggests that it’s you who is the F moron. I heard it fine, but then I have a brain 😎
Not bad but you really should be mixing a surfactant into the solution I.E washing up liquid it helps it stick to the surface and speeds the job up 3-4 times
Yes and no. On a flat surface not really important. On walls and roofs though for sure.
Buy PPE if you want to be safe.
Very very wise words - PPE is a lot cheaper than the potential results from not having it.
I think that's mold, not algae. green mold. "Mold is stubborn and much harder to remove, making it a more costly endeavor. More importantly, the greatest difference is in the way they affect your health and the health of your family. Algae growing anywhere on your home, while unsightly, will not do any harm to your health or the health of your family." Oh so that's why it got removed so easily - it is algae and not green mold.
You are totally correct - I have been to many homes with my job where the homeowner has black spots of mould all over the windows and I explain about the health factor - If I go back the next day I can guarantee it's already gone.
@@Darren-Green "Sodium hypochlorite is most often encountered as a pale greenish-yellow dilute solution referred to as liquid bleach," - so instead of renting a power washer - I just poured bleach and scrubbed it in. The smell is very strong. I think it's 7.5% concentration. So the black mold is totally gone. I had used vinegar earlier - which got rid of the green mold on top. I think I breathed in chlorine gas from the vinegar bleach reaction. oops. haha. So I could smell it through my bed room window - since I didn't insulate that window. But I survived the night and just finished off the bleach bottle on the patio. Need to get another bottle of bleach to finish the job. Cheaper and more effective than a power washer. Then there's some rust stains now underneath the black mold. So I'll have to switch back to vinegar to get rid of the orange color. I can wait - wash it off first of course. thanks
@@Darren-Green litchen
_Can I drink it tho?_
If you're a grown adult (and i'm guessing from the dumbass remark your probably a prepubescent boy trying to be clever) then you can do what you like. I am not your mom nor you consciousness. If it doesn't kill you let us know the long term problems you will face for the rest of your days because I guarantee there will be several, and if it does kill you, i'll catch your obituary in the Darwin Awards.
Good heavens if that is just 10% Sodium Hypochlorite I won`t want to see a 100% look like.
Allergies might be coz you're using chemicals a lot
Might be but having suffered hay fever on and off for 35 years I am pretty sure it was simply the high pollen count that week. :)
Bleach does the same job
That's probably because Sodium Hypochlorite is the active ingredient in bleach mate.
What ratio of bleach to water are you using Dave
@@franceslombard6751 hypo is either 10 or 15% in strength. Then you dilute that to where you want it to be.
'Bleach' such as clorox or domestos etc is around 3% strength so once you dilute that even weaker.
Bleach active ingredient is the Hypo content the rest is surfactants etc.
In short if you use domestic bleaches instead of hypo you will have to wait a lot longer for it to work.
many thanks
@@franceslombard6751 you're welcome
Sweeping up the path rather than across does,nt waste the cleaner
It's an OCD situation 😝
Vinagar
What about it?
It’s too much of a proses. A power washer would of left if Super Clean without Clorox or other chemicals.
No. A pressure washer will not kill off the microbial spores unless you use steam i.e. water above boiling temp.
Domestos is 4.5% w/w
Then it runs into the drain and into a river and poisons everything in sight. That aside it's great stuff..
At such low dilution and applied by watering can it's inactive after about 7-10 minutes. This is why I laugh when I see people saying 'leave dwell for 30 mins blah blah' Also at the dilution used it has less active ingredient than the Clorox or Domestos type products you use in you home but you still flush those down the drain don't you? 👍😁
Thought Rick may all was dead
Use sh my lord 😬
yikes!
Sorry, didn't mean to startle you Hwn.
Whats the concentration of sodium hypochlorite
The neat concentration is usually 10% - you can buy 12.5% with a shelf life of 6 months but it slowly deteriorates and settles at 10%
