Patio Cleaner - Jeyes Fluid
Discussion
Jet washed the patio but still lots of green algae, so tried Jeyes All in One Cleaner.
Applied via a spray bottle that I use for pre-washing the car. Waited 30mins. Scrubbed with stiff yard broom. Rinsed off.
Nothing. Literally removed nothing.
So figured maybe it needs to go on thicker. Coated another section with a more concentrated nozzle. Waited 30mins. Scrubbed with stiff yard broom. Rinsed off.
Again, nothing.
So then literally poured neat onto a single paving stone. Agitated with brush. Waited an hour.
Again, nothing.
Am I missing something? All the reviews claimed that it worked almost immediately, but I'm not seeing any reaction at all. Does it need to be left much longer, like overnight (days) or is there a better product I should use?

The Nuclear option is 15% Sodium Hyperchlorite (Swimming pool bleach). It gets rid of everything on patios/drives, including white spots. White spots take a while to go, but they do go. My drive was really bad and this was the only thing that worked. It's available on Amazon.
Probably over kill for a bit of alge though

OP - what did you jet wash it with if it made no difference? A water pistol?
I did some parts of our garden with diluted Sodium Hypochlorite last year - I put some pictures on this thread:
https://www.pistonheads.com/gassing/topic.asp?h=0&...
My issue with getting more of the patio and walkways done was finding a good time to do it when the cat wasn't around (as he'd want to help) and I didn't want to kill any plants by sloshing it around too much. A few weeks back I tested my 20+ year old Karcher and was surprised it still worked, so I've been working my way round the garden cleaning everything with that.
I have used it on recently laid patio with Flowpoint pointing and it's not noticably damaged that. The rest of the patio is getting repointed this spring, so the gaps where I've already knocked out the old pointing has equaled many face fulls of grit and wet trousers. It's made a huge difference though without worrying about killing plants.

I had the same problem with millboard decking due to the trees that we had.
This was their recommendation and you just spray it on and leave it and it destroys the Algae. Did it twice a year looked new every time

Cheap too £10!

As above, BAC50 is the stuff you need
Exactly this. See the results in a day or so. It dilutes to 40:1 which is still really effective and a 5 litre container from Amazon will keep you going for ages. I did mine a couple of years ago and the transformation is ace...

I thought you didn't rinse jeyes off?
I used it a few years after we moved in, the patio was filthy and had lots of lichen.
I mixed some up, poured it on and brushed it around with a broom then left it.... Nothing... Then over a few days/weeks it seemed to just clean itself!

Rinse with water
Let dry before using the surface
Just a copy/paste of something from last year on a similar thread where I got some professionals in to do my driveway and bits round the back. Subsequent to having it all done I’ve gone over it again last month with a 40:1 solution of BAC 50 in a 20 litre backpack which took about 20 mins and anything even mildly green disappeared in a day.
I’ve avoided getting it on the grass but it shouldn’t really matter. I’ve got 2 dogs so have sprayed it in the evening but obviously it’s all dried up by morning.

so....
Driveway, parking bit and some paths round the side of the house
They used diesel pressure washers. They connected up to a fire hydrant thing in the street to make sure they had enough water pressure. Can't remember how many litres/min the flow was but it was a multiple of what my little Karcher was.
Pressure Washing was followed by covering the area with Sodium Hypochlorite (so 15% bleach) and it was left for an hour then low pressure washed off. In my case it was diluted at 1:4 but apparently they do use it neat when things need it.
I also had a couple of bad rust stains from where the previous house owner had parked a skip for ever and a small area where I'd spilled fertiliser which had left a stubborn stain. These stains were additionally treated with something called Smelly Gel Pro which was left on for about 90 mins. It's a purple gloop and you can see it in one of the pics and was washed off after that time.
The results are great. They have to come back tomorrow, weather permitting, to re-sand the blocks and they are going to re-treat the rusty skip marks again just to get rid of any remaining bits. They are also going to leave me a batch of the Gel incase it needs a follow-up treatment.
The bit of path in the pic never sees sunshine so might do with a quick spray of BAC 50 as well.
Ongoing, they were recommending trying to keep on top of things on a 6 monthly basis using a biocide spray, so BAC-50 at 20:1 seems to fit the bill, on the basis that it's the green stuff that causes most of the issues rather than surface dirt so less need for pressure washing and subsequent re-sanding of the joints.
I'll see if I can get some better pics once the re-sanding has been done
