Certainly does what it said in the demo. Very pleased!

I find it an excellent weed killer. This is the best weed killer I have ever used. Sprayed on the weeds one minute and the next they're gone. Spear & Jackson - the best stuff out there!
— Jimda061, Verified Customer
Tried the product out on Monday and by Tuesday my stones had returned to their original colour and my patio flags were brighter

Used this in the morning and the weeds were wilting by the afternoon

Excellent, works very well. Even stubborn green has gone. Brilliant.
— Dovet1945, Verified Customer
Even stubbon green algae has gone within a few days that a jet wash did not remove!
— KHolmes, Verified Customer
I have used this product once so far. Couldn't believe how easy. And, a day later the green had turned white. Used it on my fences, decking and paths. Great as you don't need any elbow grease as I'm an oldie.

Within 1 day, 90% of algae has disappeared. Retreated on parts of sandstone patio and fence that I missed, and now 100% gone. Will be applying to conservatory roof soon, expecting same results.
— Aggiedaisy, Verified Customer
My husband applied Spray & Leave on the fence, patio and gravel in our garden and when I looked back 2 hours later I couldn't believe the difference. All the algae was gone. The product is brilliant and I would highly recommend it.

I have tried quite a few other brands and they aren't as good as this one.
— Laraine, Verified Customer
I was amazed to see the results of Spray & Leave. Within 3 days I saw results in colour chnages to moss and lichen. It has also killed weeds, plus seedlings of other plants that take over within the joints of paving. I am more than pleased, thank you.
— Silvergadget, Verified Customer
I have used other products that cost a lot more and they have no worked. Used Spray & Leave and I could see after a few hours the difference, with no scrubbing at all. It really works. Path looks good and it has even got rid of the weeds between the stones!
— Baskets, Verified Customer
Absolutely great. Easy to use and really does the job perfectly. I love using this product. It did my patio effortlessly and the results were outstanding!
— Haysue, Verified Customer
I used it first on my wooden garden furniture, it made a difference in two days and ready to re-oil in five days. Used it on the summer house, conservatory and block paving, even the cover of the BBQ. It goes such a long way using the spray. I would recommend this to anyone!
— Verified Customer
Treated fences first. Within 48 hours all green algae had turned white and died. Then onto the patio, again all green algae gone after a couple of days. Impressed so far!
