Advice for Cleaning Artificial Grass

There are many ways the cleaning of artificial grass can be done. It mainly depends on the nature of the mess you’re tackling. We’ve split the following section into different jobs.

Pressure Washing

After some time, synthetic grass can start to accumulate dirt. It can begin to appear darker as well, but you can refresh it with a pressure washer. Bear in mind that cleaning artificial grass with a pressure washer shouldn’t be done too aggressively. The most powerful setting is capable of displacing the sub-base, ripping the surface and removing fibres.

It’s important to lower the power of your pressure washer when using it on your fake lawn. You should test cautiously and vary your movements based on the results. The cleaning of artificial grass with a pressure washer is different per manufacturer. Some grasses are hardier than others and will take higher settings well, while budget types can break much more easily.

After pressure washing, your lawn should look refreshed and brighter. It can even make your neighbours green with envy.

Removing Ice and Snow

The colder months of autumn and winter require the most amount of work. When it gets cold enough for snow or ice, there’s different artificial grass cleaning tips to make use of.

Ice is the easier of the two problems to solve. It’s simply best to leave it to melt as it isn’t going to damage the grass. Breaking it down can inadvertently destroy your synthetic grass. If you deploy a smashing technique, this could break the fibres as they can freeze. They’re durable, but not invincible.

With snow, you can remove it from your lawn with a plastic snow shovel, but this should only be done if absolutely necessary. Caution is your best aid here, as being overzealous can rip the surface. Always use a plastic shovel over a traditional metal one, as you’re much less likely to puncture the lawn. When cleaning artificial grass in this way, you need to be careful.

Using salt is not advised when cleaning artificial grass of ice. This can block the drainage holes, which will end up pooling water on your lawn.

Getting Rid of Stubborn Stains

For spills that have hardened or attached themselves to the fibres, you should use a plastic spatula or scraper to remove as much of the mess as possible. You can then commence cleaning artificial grass with a solution of detergent and water. There’s no need for harsh chemicals.

Use a soft cloth or sponge to scrub the area and leave it to soak for at least 15 minutes. This will allow the detergent to penetrate the stain and help it lift out. Once cleaned, the area should be rinsed with clean water. For more persistent stains, a hard bristle brush can be used for cleaning artificial grass.

White Spirit for Stains

White spirit can be used, but with caution, and sparingly. It is a flammable substance, which is not something you want to have on your lawn. If you wish to try using white spirit, test it on a small area that’s out of sight.

Alternatively, you can try cleaning artificial grass by applying white spirit to a cloth first before you attempt to remove the stain. After you’ve worked the area, be sure to rinse it clean. This will eliminate the fire hazard.

Persistent Moss Growth

If you don’t actively use your lawn, it’s quite common for moss to grow on it. Even if you’re an avid user of your garden, certain conditions are perfect for moss or mould to persist. The cleaning of artificial grass for moss or mould is easier than you might think.

You should initially rinse the area down. If you don’t have a pressure washer, you can use a hose. This will remove most of the visible patches of moss. Heavily affected areas may require a bit of elbow grease. The back of a rake (without the teeth going into the grass) can tease out larger patches.

Secondly, you should treat your lawn with a moss or mould remover. There are many artificial grass cleaners that are pH neutral and environmentally friendly. Spray bottles are ideal, but you can also use a watering can or pump if needs be. Once applied, the solution should be brushed in to make sure you’re cleaning the artificial grass in its entirety. You can use a scrubbing brush or power brushes to do this for you.

Lastly, you need to rinse away the cleaning material. Providing such a deep clean to your synthetic lawn is a good habit to get into. For some homeowners, a simple pressure wash will be all that’s needed. For others, you might require a little bit of labour.

Strong Smells

Whether it’s from dog wee, animal mess or anything else, strong odours are never a welcome addition to any garden. You can make use of specialist artificial grass cleaners to treat malodours or use kitchen staples.

Cleaning artificial grass with vinegar and/or bicarbonate of soda can be done. Diluted vinegar with water can be left for 10 minutes before being rinsed off. Alternatively, bicarbonate of soda can be applied to the area and left for 20 minutes. It can then be vacuumed up.

Maintenance Tips

You can deploy the following tips to reduce the amount of artificial grass cleaning you’ll have to do.

  • Remove leaves and debris

  • Apply weed killer

  • Regular brushing

  • Remove pet waste

  • Don’t use mirrors or reflective materials

  • Avoid barbecues and fire pits

How to Make the Cleaning of Artificial Grass Easier

Remove Debris

Leaves and twigs can gather on your lawn, which compromises its quality and doesn’t look aesthetically pleasing. You should get rid of any debris using a leaf blower, plastic rake or stiff bristle brush. Cleaning artificial grass of debris is easier if you choose a day that isn’t particularly windy or if you brush in the direction of the wind.

Any organic debris, like dead flowers or plants, can encourage the growth of weeds, which is not something you want in your artificial lawn. Even airborne seeds and flower material are capable of causing weeds. A little artificial grass cleaning every now and again will save you a headache later down the line. Not only will you make your lawn look pristine again, but you’ll stop it being spoilt by weed growth.


Cleaning artificial grass prolongs the life of your lawn. Regular brushing is ideal for clearing debris, but also to keep the shape of the underlying structure. Once the base has had time to settle, brushing will keep the fibres plump and prevent them from flattening or looking a bit miserable. To keep the sponginess of your artificial lawn, go against the grain with a medium brush.

Weed Killer

One of the top benefits of artificial grass is the lack of weeds. While it’s installed to ensure no weeds come through, it can sometimes still happen. As such, you can then be cleaning artificial grass by weeding your lawn. Although the job is actually much easier because you don’t have any other plants to worry about, there are a couple of different ways in which you can perform weeding.

The first way is to simply cut off the top of the weeds that appear through the synthetic grass. This doesn’t resolve the underlying problem of the roots though, and weeds are persistent enough to keep coming back. Unlike a natural lawn, you can’t go digging up your artificial lawn with a trowel, or you’ll need more than artificial grass cleaning to fix it.

The second option for weeding your fake lawn is to treat it with weed killer. Although this can be easy to do, you must use a water-based solution or you might risk damaging the surface. When weeds die, remove them or brush them away to keep the problem under control. It can also be useful to spray the entire surface with weed killer to thoroughly complete your routine for artificial grass cleaning.

Pet Waste

There’s nothing wrong with mixing artificial grass and pets. In fact, synthetic grass can be a great option for dogs. However, the waste pets produce should be cleaned up as soon as possible.

Not only can smells permeate the area, but pet waste can be unsightly and be an unintentional obstruction for children. In terms of cleaning artificial grass, the advice is to pick up any solids as best you can before making use of an artificial grass cleaner or bicarbonate of soda, to eliminate any smells.

The final step should be to hose the area down with clean water. Diluted vinegar can also be used, but test an inconspicuous area first and leave overnight to see if it causes damage.


Though not a tip for the cleaning of artificial grass, using mirrors or reflective surfaces can be a health and safety concern. As a plastic surface, excess heat reflected onto the material can become a fire hazard.

If you want to avoid parts of your lawn melting, remove any reflecting metal objects or mirrors. Unfortunately, highly efficient windows can also be a threat, as they reflect more of the Sun’s rays than they absorb.

Fire Hazards

Linked to the previous point, if you want to avoid replacement, steer clear from certain objects. Fire pits, barbecues, cigarettes, fireworks and other items that generate heat should not go anywhere near an artificial lawn. You will ultimately melt it.

Although particularly hardwearing, artificial grass can begin to melt when it reaches temperatures around 80°C or above, depending on the material it’s made from. To be on the safe side, any heated appliances should be elevated on bricks or concrete blocks or, better yet, completely set aside from the artificial lawn on a patio or similar surface.

If you’ve melted the fibres, no amount of artificial grass cleaning can bring it back.

Additional Maintenance Points

  • Avoid sharp objects coming in contact with artificial grass, including metal outdoor furniture, high heels and studded sports shoes

  • Neat bleach should be avoided as it can degrade the fibres and cause discolouration

  • With chewing gum, remove it immediately. If this is not possible, freeze it with ice cubes so you can break it apart

  • Cut back any overhanging hedges and trees to minimise the amount of debris you’ll have to clear up

  • Some dogs may want to dig on your artificial lawn, which you should try to put a stop to. The underlay can be ripped if the behaviour is not stopped
