- In this episode of the Garden Ready for Summer Series, I’ll be showing you How to Remove Green Algae. I'll be tackling all of the green growth that we have on the brickwork and wood in the garden.
The back of the house doesn’t get much sunlight during the winter so things stay wet and then we get a covering of green growth on most of the hard surfaces.
I'll be testing out some White Vinegar against Killrock Pro Mould & Algae Remover, to see if a cheap alternative can compete with the proper product.

Check out my new upload - cleaning the path & patios - major transformation!
A little tip for you Dan. When pouring from a 5 litre container like the Kilrock PRO you used, turn the container so the outlet is at the top. You then don’t get that glug,glug splash problem and have perfect control of the liquid with a smooth pour.
Good tip, cheers 🙌🏼
I guess that you have not read the safety data sheet on this product. It’s highly corrosive and should be applied using full personal protection. It is also hazardous to marine life
That's primary school dynamics
Especially good advice when it’s a 20litre container. Doesn’t have to be fully upside down. Hold it so the opening is at the side. You’ll find the sweet spot and it pours smoothly.
That's a Huge tip. Simple and so obvious why it works. 80 years and Now they tell me! Thanks.
Well done Dan, nice to see how good a product is without buying it first and wasting money and then trying something else
Thank you 🙏🏼
Given it'll be back in a few months no matter what you do it's a total waste of time and money anyhow.
@@lksf9820 that’s a strange way of looking at it. Do you not bother cleaning your house because it will get dirty again? 🤣
😳
i was thinking what i should use to treat algae on my garden tiles and this popped up on my feed - cheers!
Glad it helped 😃
Good to know!!
😊
Looks great ❤❤❤
Thank you 😊
Great video mate! Thank you.
Thanks 🙌🏼
Great video for an age old problem. I get loads here. I will be trying the Kilrock after this but have also had success, on concrete, with Jeyes Fluid used with hardly any dilution. Thanks again for the video.
I’ve only used Jeyes Fluid for getting rid of bad smells in the yard, never actually tried it for cleaning.
Great comparison thank you so much !
Thank you 😊
I’ve been using caustic soda. Instant results and turns even old decking into a lovely honey colour. That said I applaud you for trying.
Caustic soda will degrade the surface of the wood & shorten its life.
What ratio do you use???
The Greening of Garden Timber and Concrete products seems to be more Intense last couple of Years 🤔 or is it me? ☺️
Not sure where you are, but we’ve had so much rain over the last year or so, that the timber constantly seems to be wet and growing algae
I use Wet and Forget for cleaning block paving, fencing and brickwork. Never had a problem and ive not used a pressure washer on the paving in 10 years
I’ve heard lots of good things about wet and forget, will definitely have to try that out in future.
This is amazing! I need to do this on our garden fence, it’s horrendous 😫
It’s dead easy to do, I’d use the killrock over the vinegar to make it easier. Just spray it on and let it do it’s thing.
Yeah I’ll definitely be investing in some of that, the results were brilliant!
Nice video , Ive been using a glug of bleach in a bucket of water , I pre wet the wood first before brushing it on . Not the most environmental solution ( and the opposite of your vinegar ) and the place smells like my old school hall afterwards but it works
Thank you. I use sodium hypochlorite on the patio which is just strong household bleach, it works wonders on that, comes up like new! That video is out on Sunday and a pretty satisfying transformation!
Thank you - I shall get some Kilrock - but can I use it on painted surfaces in the garden? Tne gates etc.and wooden benches in the garden,
Yes, it should work on any hard surface, including paint
Nice video thanks, where did you buy the garden sprayer and can it be used for spray painting fence panels?
Thank you. I’ve had it a few years, I got it from toolstation I think. I know you can get a ronseal version which is for spraying fences but I’m not sure I would use something like this for fences. You’d have to thin the paint loads to spray it well. For fences I use a Wagner sprayer, you can get cheaper versions now for around £20 which would be a better bet for spraying fences.
@@Renovation-Dan brilliant thank you, liked and subbed
@@darattaqwa thank you, I appreciate that 🙌🏼
Wet and forget from costco is a great product for the job.
Heard lots of good stuff about it. Will definitely have to try it out
Couple of bottles of neat bleach - JOB DONE!
You could add a bit of salt to the white vinegar solution to.
I've just sprayed the shed and it's killed the algae in a few days.
BTW white vinegar is acetic acid and some commercial eco 'remover' products will have this in their ingredients.
It's used because it's biodegradable.
Thanks for the tip. Someone else said they add salt and spray their driveway with it and it works really well.
@@Renovation-Dan
It also works as a weak weed killer, although it only really damages the leaves, it doesn't reach the roots.
@@Paul-yh8km it probably works quite well on block paving to prevent weeds before they grow in the gaps
Jet wash cleans it in minutes. Ive tried all sorts of stuff a bit of bleach in a bucket also works fine.
This particular wood is a nightmare to clean with a pressure washer, it either streaks or at higher pressure starts to damage the wood fibres. The bricks and pointing are 130 years old, so I won’t use a pressure washer on them as it damages them and pulls the lime mortar out.
I use Patio Magic like wet and forget just spray on and leave very good product
Not one I’ve tried before but I imagine most of the spray and leave products are fairly similar
Bleach 50/50 in a sprayer 👍🏻🙋🏼♂️🏴
Washing powder mixed in water works aswell
That’s not one I’ve heard before, I’ve heard of people using fabric softener for cleaning artificial grass and removing smells, but not washing powder for getting rid of green algae
Biological washing powder.
👍
Can you use this on painted fences and brickwork?
Yes it shouldn’t be a problem
Hi. Do you think the Kilrock would kill moss on tarmac?
I’ve used it on moss before and it does work but it takes a while. In the next video I clean the patios and use sodium hypochlorite to remove stains etc. Theres some moss on the edge of the patio where there is a sleeper and brick border and the sodium hypo kills it pretty much instantly. If you haven’t used it before, it’s pretty strong stuff but it will get rid of moss at a fairly diluted solution.
I look forward to that video. Cheers.
@@bobi2582 thank you. It goes live on Sunday.
White vinegar is about 30p a pint in Tesco, about 1/4 the price of paying for 5L on Amazon
I’m not sure what you want me to do with that comment… It’s a bit late to take send it back and swap it now 😂
@@Renovation-Dan I’m fairly certain I’m not the only person who reads comments on videos like this, I might save someone some cash if they decide to go down the vinegar route. There’s plenty of other uses for it aswell…
@@cjsutcliffe I would say I’d stick to just putting it on fish and chips but I don’t even like it 🤣
Not sure why you did not mention the vinegar strength, but it's usually 5%.
You can buy vinegar for much cheaper, just look further down, you can get like 20l for near same price. Vinegar can be used to clean pretty much anything so don't buy expensive. A few more washes and it can do the same, I reckon.
I’m not sure there’s many places selling 20 litres for near £8.95
Great idea but Wickes is the only place to sell it. You can't get it here in Northern Ireland and Wickes won't deliver it either. 😢
I didn’t realise it was only wickes that supplies it. I’ve had a quick google and can’t see anywhere else. I’ve had a few people recommending “wet and forget” as a similar product with good results
Is there a need to clean it beyond looking better? Does the algae cause harm?
Some algae can be harmful but to be honest I have no idea about the different types. I doubt these ones are harmful to humans or pets (other than being slippery) I do it for the looks and to prevent the wood potentially rotting sooner
All overkill, just use a 50/50 water bleach dilute in garden sprayer, soak all the green stuff then hose away a day later - just be careful with the run off around plants.
That’s more effort than the killrock, which you just dilute, spray on and leave. I wouldn’t want to leave bleach on the surfaces in the garden having a dog either.
@@Renovation-DanJust read the data sheet for Kilrock, it is no better than bleach.
Love a home brew solution but it seems like it’s worth paying for the proper stuff this time 🤔
The vinegar did work, but doesn’t really work out any cheaper and the proper solution is definitely better
From experience use Wet & Forget algae and mould remover, boom, one spray and done, has been incredible on my decking!
Lots of recommendations for wet & forget, so I’ll have to try it some time
You could just fill your sprayer with water and add a couple of cups of thick bleach to it. Cost about 25p per sprayer container full. btw bleach does not harm bricks or mortar.
I’ve heard a lot of people (including lime suppliers) say that the sodium in bleach reacts with the lime in lime mortar causing damage. Cement mortar would be fine though.
@@Renovation-Dan I've heard that you can get salting when used on lime mortar, I think this is more cosmetic than affecting anything structural. But most mortar nowadays is just made with sand and cement and doesn't contain lime.
@@caparn100 a lot of the stuff I’ve seen doesn’t really specify the damage, so it may just be cosmetic. The mortar on our house is mostly original lime mortar, other than the various patches that have been repointed over the years with sand and cement. The patio always gets cleaned with sodium hypo bleach and it works a treat!
@@Renovation-Dan For my patio, a couple of times a year I use a bucket of water with about 1/4 of a bottle of bleach and just brush it over and leave it to dry. It does a good job , and every couple of years I jet wash it. It's quite dilute so doubt you will get much salting, you could try it on an inconspicuous part of your house and see how it goes, maybe make a video of it. I found that jet washing does the most damage particularly if you have the pavers that are concrete with a coating to make the look like sandstone. The jet wash wears away the surface and exposes the concrete paver if used too much.
@@caparn100 there’s a video on the channel cleaning our patio, it’s sandstone so pretty tough but I know a lot of people make a right mess trying to jet wash stuff. I’ve seen a few decks people have tried to jet wash and made them look 10 times worse!
I use jeyes fluid
I had another comment from someone who uses jeyes, I’ve never tried it for something like this though
I P1SS myself laughing every year at the Woman / Family next door, she'll jet wash her driveway about 72 times from Now till Oct - maybe even a few in November.
I do mine ONCE, and with No Jet wash.
Vinegar Concentrate, 1 cup of salt & about 20 mil of washing up liquid, I mix up one of those big ''Water at Work bottles'' then add to an old watering Can that holds 5L, Usually the Big ''Water at Work bottle'' is enough for the full driveway, I done it about May last year and even now it still looks fine, zero weeds, zero moss, but I will still do it again in a few weeks just to keep next door guessing lol 😉
Vinegar Concentrate - 30% is plenty strong.
cup of salt
20 ml of washing up liquid
Shake well and apply, large spray bottle or watering Can
BOSH!
Ya welcome.
I do mine once per year and that’s plenty for me 🤣 crazy that she hasn’t asked you for some tips!!
Thanks, I’m going to try this method 👍
Diluted sodium hypochlorite does the job of killing/removing moss in seconds.
I use sodium hypochlorite to clean the patios and path in the next garden video. Great stuff.
Good to know 👍🏻
@@Renovation-Dan In a very diluted state, it does wonders on fences and furniture also.
Make sure to soak any areas where it touches plants/grass afterwards otherwise it'll kill it.
@@MrSmith_agreed, also soak wood and plants before spraying as it won’t damage the wood fibres and will run off plants and grass on contact.
Vinegar is highly, highly overrated as a home cleaning remedy. First off, it's an acid and should not be applied to a myriad of materials that it will damage. Those galvanized hinges on your bins will suffer from being exposed to vinegar. Unfinished wood will not fair well in the long term after vinegar exposure. Additionally acids are not completely removed by water rinsing unless you apply huge amounts of water for a very long time. Neutralizing the acid with a sodium bicarbonate solution would be a good idea, but even that might not get into all cracks and crevices. Side note - don't put vinegar in your clothes washer or dishwasher as it can damage rubber and plastic parts. The only thing I use vinegar for generally is killing weeds - it's pretty good at that.
At least you can use any left over vinegar on your fish 'n' chips!
It has to be malt vinegar for a chippy… although I don’t actually like vinegar 😅
What's a worinan?
I have no idea??
Brinton's is your Boy for this it works wonders and you can even spray it on your annoying neighbour's cat that visits your property to leave you special presents 😶
I’m intrigued as to wether it’s the neighbour who is annoying, or their cat 😂
@@Renovation-Dan Brilliant reply and the truth is they are both equally annoying 😀
@@Mike_5 I hope it’s just the cat leaving you special presents then! 😬
@@Renovation-Dan Yes that opens a whole new world of possibilities to consider
Thought this was an old video as Kilrock is now unavailable 🤷🏻♂️
It’s still in stock in our local wickes. Apparently wickes is the only place to stock it now though
It’s still in stock in our local wickes. Apparently wickes is the only place to stock it now though
Have been using sodium hydrochloride 15 for many years most farm suppliers stockists sell 25lt for 28£ just mix 5 to 1 with water use a spray or a watering can all the other products are a rip-off
I’ve just cleaned the patios with sodium hypo, which is the next video. Great product.
Vinegar might be the best of a bad lot.
I’d say the killrock solution was quite a bit better than the vinegar.
KilrockPRO Mould & Algae Remover is like gold dust, out of stock everywhere near me😒
I didn’t realise until someone else commented how hard it was to get hold of!
No vinegar on lime mortar - it will disolve it!
To be honest the vinegar wasn’t worth the extra effort, so I won’t be using that again anyway.
white distilled vinegar….
Just use wet & forget simple !
Lots of comments recommending wet & forget, I’ll have to try it some time
@@Renovation-Dan little tub 1 litre goes a long way not cheap but used it on my outside walls that were north facing and greener than the lawn…came back a few days later and the walls were whiter than a vergins
@@1664smudge I looked at it a while ago and I think the prices must have been up, because when looking this time round it seems to have dropped a lot from what I remember. I think I’ll get some to spray our roof, I had someone else saying it worked really well for roof cleaning
Bleach, caustic soda, biological washing powder! ☹️All these are bad for the environment and aren’t recommended for first choice as cleaners because of residual damage to good organisms. Dan is right. The Killrock is safe and works well when diluted as instructed with no environmental damage.
Buy hypochlorite from a farm supply store, £20 for 20 litres, apply to green moss and algae, ten mins later …. Gone !
The next video is cleaning the patios and path, I’ve used sodium hypo on that which works well. I got the slabs second hand and they were pretty much black with lichen and the hypo had them looking like brand new again.
Is it ok on all surfaces, tarmac and plastic etc
why not just use hard brush and water? These chemicals may or may not destroy wood. who knows, i'am not a scientist, but better to be on a safe side if in doubt.
A few reasons, on this particular wood it doesn’t scrub off, it’s quite a fibrous soft wood so the green staining gets right into the wood. I would normally pressure wash hard surfaces like brick, but the pointing on the bricks I did (outbuildings) is in fairly poor shape and would be damaged by a pressure washer or a hard brush. A modern Portland cement pointing would be fine to scrub.
The best way is just to leave it alone and accept that's the way it's supposed to be in Winter. Splashing chemicals around is a complete waste of time and money and bad for the environment. The green will go soon on it's own and return next Winter. You're effectively chasing your own tail and filming it which is akin to admitting you have the intelligence of an animal.
I’d rather spend my time keeping my house in good shape than commenting pointless comments on RUclips 🤷🏻♂️
Well here we are at the beginning of May and my composite decking shows no sign of 'improving'. Granted it doesn't get as bad as wood, but with the foreseeable weather forcast not amounting to many sunny days I cant see the algae disappearing anytime soon. So I will be jetwashing in order to have a pleasant area to sit in. I only need to use a small amount of washing up liquid to help the job along, but I do not blame people for wanting a clean and pleasant area to relax in😊
You've got some green growth on your body too, are you aware how toxic they really are.
I sprayed the killrock on but it didn’t seem to budge them 🤷🏻♂️
Just use a biocide and leave it on... No need to scrub.
That’s effectively what the killrock pro solution is. You just spray that on and leave it.
No need for all this product. Just use bio washing powder in the normal ratio with water.
We use non bio pods, so would have had to have bought bio. Maybe next year I’ll do a comparison of all the suggested options in the comments
Please try and keep blogs real. Your footwear was not suitable for either chemical spraying or pressure washing. X
They aren’t waterproof but thankfully my feet are, so no issues 😅
I think you should K-render you back of house - look better.
Unsure if that’s a serious comment or not but there’s no way I’m rendering over original Victorian brickwork, that would be sacrilege!
You need to get a shave , grow some hair and scrub the ink that’s poisonous to your 🩸 bloodstream off first. 😊
I’ll get straight on with that now, sorry for my disappointing life choices, I’ll try not to let you down in future 🥲
@@Renovation-Dan excellent 👌🏻
Wet n forget
What a load of rubbish - just buy some spray bleach / £1.99 from Tesco - for bigger jobs including large patios / wet the patio and squeeze the domestos out all over it and brush it in - results a near new patio outcome / these people online our online wouid would have you buying a jcb to dig a hole to plant a flower / 😂
That works out more expensive than the killrock pro. Even if you buy Lidl bleach that costs 60p per litre, it adds up to £30 to make 50 litres worth, more than twice the cost of the killrock pro. For cleaning the patio I use sodium hypochlorite but using bleach isn’t as pet or kid safe and you obviously need to be very careful around plants.
Thanks for the tip I only have a small area to do so this is ideal
Bleach is very effective BUT is a dangerous and Caustic substance to be spraying about.....
