Jarder Spray & Leave 4 x 5 Litre Concentrate Cleaner - Patio Fencing Decking - Green Mould & Algae Killer (20L)

Used this last year on patio, bench and fencing. Still no signs of green algae at all, so lasted through the winter and still going strong. I used it neat with a sprayer for fast results. Great stuff, never even needed to use my power washer at all last year.

Used on paving and extension roof. Wire brushed and swept worst affected areas first and then applied using watering can with rose fitted instead of sprayer. Doesn’t go so far but doesn’t dry out so quickly. Also avoid applying in hot sun. Results aren’t instant but seems effective

Absolutely brilliant stuff, I’ve just bought a pack of 4 for the eighth time, I cleared our back patio, swept up the leaves and made a late afternoon application yesterday mixed 1 to 4 with water as usual. Large areas are already showing a distinct improvement and having used up the last drum today, I’ve just sat down to order more….I’d give it ten stars if I could! Bonus is that it doesn’t leave a smell of vinegar like some others do.

The cleaner seems to work just as expected and the four pack is pretty good value.

Great product but dreadful delivery service. Drive left the package on the roadside and just drove away without telling anyone

Works well take a couple days to clear but does a good job, especially on black mould

Good product

Have both these patio cleaners a few times now, they work brilliantly, well worth the money and fast delivery
