GreenBlade Green Guard 5 Litre is a concentrated enzyme gel for artificial grass laid over concrete, paving or decking. The thicker formula clings to grass fibres to help tackle pet odours where drainage is limited. Choose the larger size for bigger lawns, kennel runs or repeat treatments.
Check the base beneath the turf. Use the hard-base dilution for artificial grass over concrete, paving or decking. Use the traditional-base dilution where applicable.
Measure a batch to suit the area. For a smaller hard-base mix, combine 500 ml of Green Guard with 1 litre of water to make 1.5 litres.
Remove solid pet waste and loose debris. This helps you distribute the treatment evenly.
Brush the fibres upright first. This helps the solution reach the grass and backing.
Apply close to the grass. Work evenly across the whole area, including edges and pet toilet spots.
Choose a cooler time to apply. Avoid hot, direct sunlight.
Check the Green Guard label. Follow the instructions for your installation and read the safety precautions.
Prepare the grass. Remove solid pet waste and debris, then brush the fibres upright.

Green Guard has a Watermelon Breeze fragrance.
Green Guard 5 Litre is an artificial grass cleaner for turf laid over concrete, paving or decking. Its thicker bio-enzymatic gel helps the treatment stay in contact with the grass fibres where drainage is limited, so it can work on residue associated with pet odours.
Keep Green Guard on hand if your artificial lawn is used regularly by dogs or you look after a larger area, such as a kennel run. GreenBlade also lists suitable indoor turf installations such as gyms. After application, the Watermelon Breeze fragrance leaves the treated grass smelling fresh.
One container holds 5 litres of concentrate. For artificial grass over a hard base, mix one part Green Guard with two parts water. A full container makes 15 litres of diluted cleaner at this ratio. For a traditional artificial grass base, use one part Green Guard to five parts water, which makes 30 litres from the full container.
Measure smaller batches at the same ratio whenever you need to treat a smaller area. Apply evenly with a watering can or suitable pump sprayer, brush through and leave the grass to dry fully.

Fresh enzyme cleaner that removes pet odours from artificial grass This cleaner has a fresh scent and uses enzymes to break down odours effectively, especially in areas used by dogs. It sprays evenly and rinses away cleanly without leaving residue or dulling the grass.It’s ideal for keeping artificial lawns hygienic and fresh, and it noticeably reduces pet smells after just one use. A reliable cleaner that helps maintain a bright, clean outdoor space.Verified
Working well in initial testsWorking well in initial tests This is a little on the pricey side for the amount you get but it does dilute quite a lot so goes a reasonable way.Easy to use by just adding it to water and pouring it over with a watering can.It smells nice but that doesn't last too long or get overpowering which I feel is a good thing.It does seem to lean although my major test is yet to come at a holiday home so should there be any issues I will update this review.Seems good quality and cleans well so hoping for good results when I treat a much larger area.Verified
AstroTurf cleaner Minty scented. Easy to use and dilute to desired strength.The upper end of the price for the quantity you receive - I diluted this with a 1 part liquid 5 parts water and I could smell the fragrance for a few hours but with the hot weather the urine smells promptly came back. Have used almost the whole bottle over two applications so it's quite expensive but for smaller areas may last longerVerified
GreenBlade Green Guard Artificial Grass Cleaner & Odour Remover, 1L 1 Pack My ExperienceRight, morning everyone! Now, if you keep dogs, you know the struggle in winter or when it’s absolutely tipping it down outside—the ruddy dogs only want to go out if you give them a gentle little nudge on the end of your foot (only joking, of course, just a little budge with the boot!). Because of that, I set up a dedicated patch of astroturf for them near the house so they can do their business quickly without getting bogged down in the mud. It works smashingly well, but the smell gets right on your nerves!And I’ve got to say, this stuff is proper job!What I really like is the thick gel consistency. Unlike all sorts of other watery cleaners I’ve used in the past that just wash away in a flash, this gel actually feels like it’s clinging right to the "blades" of grass and backing so the bio-enzymes can get to work. I’ve used it on the main path as well as the astroturf patch, and it works equally well on both. It definitely removes the lingering wee smell completely rather than just masking it, leaving behind a nice fresh Watermelon Breeze scent. Ideal bit of kit for keeping the yard smelling fresh!The ProductThe GreenBlade Green Guard Artificial Grass Cleaner & Odour Remover (1L Bottle). Made in the UK, featuring a thick probiotic bio-enzyme gel formula with a Watermelon Breeze fragrance. Specifically engineered to cling to artificial turf fibers on hard-standing bases (concrete, patios, decking) to eliminate dog urine and pet odors at the source. Safe for pets and children once dry.The Ideal User / Deal BreakerAn essential buy for dog owners, pet keepers, and homeowners who have artificial grass laid over hard surfaces like concrete or patios and need a thick cleaner that won't immediately drain away. The deal breaker is if you need a pre-attached hose-end spray bottle for a massive multi-acre field, as this concentrated gel requires manual dilution in a watering can or sprayer.SummaryA remarkably effective, thick probiotic gel cleaner that clings where it's needed and completely neutralises stubborn pet odours. It does a fantastic job keeping the dog patch and path fresh, keeps the yard setup running smoothly, and gets 5 stars from me!Star Rating: 5/5Verified
Fresh effective cleaner that removes odours from artificial grass This cleaner has a fresh scent and works well on artificial grass, especially in areas used by pets. It removes odours effectively and leaves the surface looking cleaner without residue.The area cover depends on what surface you have under the artificial grass, if it’s concrete it’s a much smaller ratio so doesn’t cover as much area. I have a small courtyard and had to buy another bottle to get the proper coverage. It is overall a helpful product for keeping artificial grass fresh.Verified
Really Handy for Keeping Our Artificial Grass Fresh. I bought this because we have artificial grass and, with having a dog, it can get a bit smelly, especially when the weather is warm. I wanted something that would help get rid of the smell without using anything too harsh.I've been really happy with this so far. It's a thick gel, so it doesn't just disappear into the grass as soon as you put it down. It's easy to spread around and doesn't make a huge mess while you're using it.The main reason I bought it was for the dog urine smell, and it has definitely helped. After using it, the grass smells much fresher and the usual doggy smell is noticeably reduced.I also like that it doesn't have that really strong chemical smell that you get with some outdoor cleaners. The 1-litre bottle is a good size too, and I think it should last me quite a while.I've also used a bit on the patio where the dog tends to walk after going outside, and it's been useful there as well.Overall, I'm really pleased with it. It's easy to use, doesn't smell harsh and has made a noticeable difference to keeping our artificial grass smelling fresh. It's definitely something I'll keep using, especially during the warmer months.Verified
Very effective - nice smelling too I’m a recent convert to the world of artificial grass, having been inspired by a neighbour who got a patch for her dog to use. Our back garden is all stone flags and raised beds so it’s not welcoming for our little dog when she needs to answer a call of nature at short notice. In most cases our regular walks are enough for her needs, but occasionally she needs to go outside and it just won’t wait. Artificial grass is the answer to that problem and this cleaner is the solution to the problem that arises afterwards.It’s more than just a general cleaner that uses an anti-surfactant to remove dirt, although it does have that element. In this product there’s an enzymatic element that breaks down the stuff that causes odours: that detritus has attached itself to the inner pile of the artificial grass and as it decays it produces the odour. This cleaner helps to break that down rather than just trying to release it so it can be washed away.It really does work well and I’ve found it best to use it last thing at night and let it sit until morning. There’s a fresh odour that adds to the general feeling of cleanliness and makes the grass much more pleasant to be around.It’s not cheap so you’ll have to make up your own mind about whether it’s good value for money. I can say that it definitely works though, and perhaps that effectiveness is worth paying for.Verified
Leaves a nice smell GreenBlade Active Max Artificial Grass Cleaner for Dogs is a useful solution for keeping artificial grass fresh, clean and more pleasant around pets. The bio-enzymatic formula is designed to tackle dog urine odours rather than simply covering them up, making it particularly suitable for areas that are regularly used by dogs. The Cool Mint scent leaves a fresh fragrance after application without being excessively overpowering.The 1L bottle provides a reasonable amount of cleaner, especially because it can be diluted at a 1:5 ratio. This makes it practical for treating larger areas of artificial grass while keeping usage economical. The cleaner is straightforward to incorporate into a regular garden cleaning routine and can help maintain a fresher-looking and better-smelling lawn.The product is especially convenient for households where artificial grass receives frequent use from dogs, as unpleasant smells can otherwise become noticeable during warmer weather. The mint fragrance gives the grass a clean, refreshed feel after treatment. Overall, GreenBlade Active Max combines odour control, a pleasant scent and a concentrated formula in a convenient 1L bottle, making it a practical artificial grass cleaner for dog owners looking to keep outdoor areas hygienic and fresh.Verified
Safe, UK-made gel for artificial grass and patios If you’ve ever spent a summer wondering if your garden is a dog loo in disguise, this GreenBlade Green Guard cleaner is a bit of a revelation for artificial grass and patios. I picked up the 1L bottle after trying a few “fresh scent” sprays that just left the lawn smelling like a perfumed kennel. This one’s a thick probiotic gel, which means it actually breaks down the source of the pong rather than just layering on a fragrance. The science bit is simple: good bacteria munch away at the nasties, so you’re left with genuinely neutral grass, not a chemical cloud.I used it neat on the worst patches (thanks, spaniel) and diluted for a general spruce-up. The instructions are a bit vague on ratios, so I played it by ear, but it worked well both ways. The lack of a strong scent after use was a surprise – it doesn’t leave your garden smelling like a lemon grove, but it does mean you know the odour’s actually gone, not just hidden. The 1L bottle covered my small lawn and a couple of high-traffic patio spots, but if you’ve got a big garden or a pack of dogs, you’ll probably need more than one bottle for a deep clean.What I hadn’t expected was how safe it felt to use – no gloves needed, and I didn’t worry about the kids or the dog rolling around straight after. It’s UK-made, which is a quiet reassurance if you’re fussy about what goes on your grass. The gel consistency means it clings to the blades rather than running straight off, but it does take a bit longer to rinse out of a watering can than a thin liquid. For anyone with a shared garden or a communal play area, it’s a relief to know you’re not leaving behind anything harsh or toxic.One thing to keep in mind: there’s no lingering “clean” smell, so if you’re after that just-mown fragrance, you’ll be disappointed. Also, the lack of detailed dilution guidance means you might use more than you need at first, which could get pricey if you’re treating a large area regularly. Cleaning up is easy – just a quick brush and rinse before applying – but the bottle does get a bit sticky if you’re not careful with the cap.For the price, it’s good value for small to medium lawns, especially if you’re fed up with chemical sprays that don’t actually solve the problem. If you’ve got a massive garden or want a strong scent, you might want to look elsewhere, but for most pet owners, this is a practical, genuinely effective fix. 4 stars – it does what it promises, is safe for the whole family, and finally lets you enjoy the garden again without holding your nose.Posted on Google![]()

Our artificial grass was looking a bit tired and we weren’t sure what to do with it as it’s in a commercial setting in our pub restaurant premises so has a lot of footfall, spilt food and drinks. My friend recommended giving Green Blade Cleanse a call and I’m so glad I did. They recommended using a product called cleanse and what can I say! It looks like it’s just been laid and it smells amazing.Verified
Brilliant product, fantastic results Fantastic product, smells incredible and works perfectly, artificial grass has come back to life and all pet smells have gone.Load more
