The best patio cleaners for effortless cleaning 2025

For use on patios, decking, fencing, brick, and more, Jarder Spray and Leave patio cleaner will make all your outdoor areas look brand new, easy breezy. Designed to be diluted, one five-litre bottle of Jarder Spray and Leave makes around 30 Litres of solution capable of covering a 240 square metre area. This is sold in both single and great value multipacks.

There's no need to scrub or pressure wash, simply mix, spray on and leave for results that'll show in a matter of days and last for up to six months. It'll also prevent regrowth of mould and algae and is totally safe once dry around children and animals.

Tried and tested by Modern Gardens Commerce Content Writer Amy-Mae Turner: "I've always been reluctant to use chemicals in my garden but I was persuaded to try this Jarder solution as it's biodegradable, non-caustic, and doesn't contain any acid or bleach.

One of the levels in my garden is a horrible concrete area that rain water pools on and I've always struggled with keeping it clear of algae. My usual course of attack is soapy water and a stiff brush, so I was curious to see if a special solution would make life easier.

I used this neat (you are supposed to dilute it to 1:5) as I only wanted to test a small patch. I simply tipped some solution directly on the ground, leaving the areas around it untreated to work as a control comparison. As you can see from the image this has completely got rid of all the algae where I applied it. Jarder says this can take two to three days to work, but it worked for me in a matter of hours.

I'm now tempted to invest in a pump action garden sprayer so I can use this cleaner - to the recommended dilution levels - to finish cleaning the concrete and to use in other areas of my garden."

Tried and tested by Modern Gardens Commerce Content Writer Amy-Mae Turner: "I tested this Resolva cleaner in various areas of my garden and it worked well on concrete, bricks, terracotta, and paving - eventually. This option requires patience as it certainly doesn't give overnight results, but crucially the results do come as you can see from the image above. I sprayed this solution on the top brick and you can clearly see the difference between that and the untreated brick beneath it."

"I loved that this was a spray-on solution so I didn't have to fuss with any kind of dilution process. The convenience of the spray application is balanced by the fact you're not going to want to use this on large areas - your hand would get seriously tired! It should be noted that this is available in a larger bottle with an integrated spray applicator for large patios.

I recommend this Resolva spray patio cleaner for spot cleaning problem areas, for smaller spaces, for plant containers, and for use on weathered garden furniture."
