The Best Patio Cleaners of 2021 – UK Buyers Guide

Receiving guests or even just coming home from a day’s worth of work – nothing beats a clean patio greeting you with open arms. It’s not going to stay that way all the time, sadly, as the dirt, grime, and even plant growth can ruin the once-immaculate look of your patio. Damp weather can further algae, moss, and mildew occurrence on the surface, not only making it untidy to look at but posing the risk of slipping as well.

Luckily, it doesn’t take much effort to clean that gloomy, greenish look off your patio’s face today – patio cleaners and detergent solutions are widely available and can help greatly with minimal need for backbreaking scrubbing and the likes. These work fine with brushes and sprayers, and some are compatible with pressure washers, improving convenience by a significant amount.

Not all patio cleaners are made equal, however. Not every formulation has the same strength or efficacy to do the job. Worry not, however, as we’ve rounded up some of the best patio cleaners one can buy in 2021.

Best Patio Cleaners in the UK – Recommendations

Pro-Kleen Patio Cleaner

Want a hassle-free patio cleaning experience? The Pro-Kleen Patio Cleaner does that and more thanks to its ingenious formulation. This patio cleaner boasts a zero-bleach, non-acidic, and biodegradable formula that is safe to use even with plants around the intended area to be treated. The pH8 rating doesn’t only mean that it is gentle to plant life, but to your hands and any living thing it comes to contact with.

While the Pro-Kleen Patio Cleaner is gentle in that aspect, it’s absolutely unforgiving on patio grime and growth. By mixing one part of the formula with four parts of water, you’ll instantly have a formidable solution that can clean any hard surface with ease. More than patios, this cleaner can target outdoor furniture and fixtures, driveways, and even roofing for a comprehensive crackdown on grime. Since the formula is so powerful, you won’t even need to use a pressure washer to do the job – simply spray or splash the solution on the area you want to clean and watch as it takes effect in a few hours. Give it a few days, and there will be no trace of what was there before, although you can definitely give it a good scrub or two if you feel the need to.

For every five liter gallon, you get 25 liters of cleaning solution that’ll last you for a handful of uses. You don’t need to use it all in one go, though, as the Pro-Kleen Patio Cleaner has an unlimited shelf life. Simply stash it away once you’re done with the cleaning job and retrieve it as needed. Take that moss and dirt-crusted patio back to its glory days with the powerful yet gentle Pro-Kleen Patio Cleaner.

Wet & Forget - Moss Mould Lichen & Algae Remover

Another great option to go with for your patio problems is the Wet & Forget – Moss Mould Lichen & Algae Remover. As the name suggests, you can simply leave the solution on for a couple of hours to days to get the desired effect. It is also economical as a five-liter gallon can make up to 30 liters of patio cleaning solution, covering an estimated 100 to 300 square meters of area depending on the surface’s porosity. Speaking of surfaces, this patio cleaner isn’t only exclusive to patios, but services tarmacs, roofs, and tennis courts with ease as well. Say goodbye to mould, algae, moss, lichen, and more with this formula’s scouring power.

As for scouring, there is absolutely no need for it with the Wet & Forget – Moss Mould Lichen & Algae Remover. The formula is intended to do the job by itself to reduce or eliminate the damage caused by scrubbing and water abrasion, although one can definitely use a brush or pressure washer should you feel the need to. It also has a residual effect that lets certain ingredients stay active for some time to prevent premature contamination of the surface – perfect if you want none of that slimy green coating coming back soon.

The Wet & Forget – Moss Mould Lichen & Algae Remover isn’t based on bleach so you won’t have to worry about damage to plant and animal life while ensuring that the surface doesn’t suffer from chemical damage as well. The formula also has an unlimited shelf life, so feel free to store it once you’ve prepared the needed amount for cleaning. One slight con about it is it doesn’t act as fast as other cleaners, but it isn’t something you should really worry about as you literally don’t need to work for it.

Lichens are among one of the most annoying growths to clean on your patio or garage way due to its resilience. Fret not, however, as the Floorseal Patio Black Spot Remover Plus has a formula specialized to remove black spot lichen without the use of harsh chemicals and methods. The formula is effective on many kinds of surfaces, like Indian sandstone, York sandstone, and concrete, although the time it takes to remove discoloration and other growth may vary due to these surfaces. As such, the manufacturer advises users to carry out small test areas to determine the dwell time. They also strongly recommend keeping the area visibly wet to ensure continuous efficacy.

The Floorseal Patio Black Spot Remover Plus comes in different volumes, with the base one being a standard five-liter container that can cover up to 20 square meters. Its formulation is intended for black spot lichen removal and is more potent than its competitors in terms of efficacy, although you can definitely use it in tandem with a pressure washer if you deem it necessary. As it is intended to be left to take effect, prepare the area to be treated by pre-wetting it with water and continuously spraying the product to keep the process going. This should be strictly observed to achieve the best results.

As the Floorseal Patio Black Spot Remover Plus is specially formulated for black spot lichen, which is totally different from the usual moss and mould problems of patios, so it is understandable that the dwell time is much longer than usual. The manufacturer also recommends using the formula with their Sealer and Colour Intensifier to improve vibrancy and inhibit growth, or the Preventer Plus that prevents the return of black spot lichen.

Patio Magic! Concentrate

Our suggestions above aren’t offered in smaller containers, making them quite overkill for a small homeowner’s needs. For those that want to be economic in their patio cleaning needs, the Patio Magic! Concentrate comes in 2.5-liter containers instead of the standard 5 L offerings. Its formulation is one of the most powerful around as well, sold in concentrate form that needs to be diluted in water to maximize efficiency and surface area coverage – which is an amazing 85 square meters to boot.

To prepare the Patio Magic! Concentrate, mix one part of the formula in four parts of water. It can be applied via sprayer in its lonesome or used with a brush or pressure washer combination, whichever fits your cleaning needs. When applied, the solution takes about two to four days to fully manifest its algae, mould, and lichen removal effect. While it is inherently powerful thanks to the biocides in the formulation, it is fully biodegradable and breaks down in garden soil to prevent pollution and contamination. As with most cleaning solutions, one should take extra care in handling and preparing this patio cleaner as it is a potential irritant.

While the Patio Magic! Concentrate is a potent patio cleaner, the product’s formula is best suited to prevent algae, moss, and mould re-growth rather than a direct removal solution. As such, one can use another cleaner to thoroughly clean the surface and then apply the Patio Magic! Concentrate to prevent the growth of these patio menaces. The manufacturer also suggests using the solution on a sunny day to increase the effectiveness of the formulation. What’s amazing about the re-growth prevention capabilities of this patio cleaner is its lengthy coverage that lasts up to six months minimum and stretches up to nine months at max.

Jarder Spray & Leave

Revamping your patio’s look is effortless with the help of the Jarder Spray & Leave cleaner. It boasts a powerful formulation that has over 50% more active ingredient versus competing brands, making it an effective solution for removing mould, algae, and moss growth on the desired area of treatment. It comes in a five-liter container that can yield up to 30 liters of cleaning solution for maximum efficacy which can cover a whopping 240 square meter area with ease. For areas with lesser growth or dirt to clean, the dilution rate can even be ramped up to 1:10 to economize for the next cleaning period.

The Jarder Spray & Leave patio cleaner can be applied via a low-pressure garden sprayer or a watering can – it doesn’t need the harsh pressure washer method or be accompanied by scrubbing to take effect. Simply wait for 2 to 3 days for the results to show up. Apart from removing all the unwanted growth and dirt from your patio, this cleaning solution also prevents regrowth. The formula penetrates the surface you want to clean, providing a growth inhibitor for algae, moss, and mould for about six months.

Apart from patios, the Jarder Spray & Leave cleaner can also be used on various types of surfaces like roofing, aluminum and PVC windows, guttering, terracotta, solar panels, wood surfaces, and more. It is also quite effective with multiple stone types like sandstone, Yorkshire stone, limestone, and granite, among others. For maximum effectiveness, the Jarder Spray & Leave solution should be applied in dry weather, preferably when rain isn’t expected in an 8-hour period, although working under direct sunlight might cause the solution to evaporate prematurely. While the formula is non-caustic and biodegradable, avoid spraying near bodies of water or plants as it is toxic to them.

Kärcher Stone and Facade Cleaner

If you need a patio cleaner that can be used with a pressure washer safely, say no more. The Kärcher Stone and Facade Cleaner is formulated to be most effective when used with such application methods. While the formula performs optimally with Karcher’s own pressure washer line, you can also use it with any other pressure washer without problems. This cleaning solution has a 3 in 1 detergent formulation that helps scour and remove unwanted growths such as mould, algae, and moss fast.

The Kärcher Stone and Facade Cleaner’s formula claims to have an active dirt remover as well as added protection against the elements to keep your patio looking clean for a long time. Furthermore, one can use it on multiple surfaces like stonework, aluminum, and PVC, among others. This means added versatility when it comes to applications like using it on walls, the roof, and even your car.
