How to Clean Artificial Grass - Easily Removing Algae and Bacterial Growth

Switching your natural, traditional lawn for artificial grass is great as it allows you to keep your garden looking pristine without spending as much time caring and tending for it. However, even your artificial grass will require some cleaning and maintenance to keep it looking its best, and to remove any pesky bacterial growth such as algae and biofilms - not to mention contaminations from nocturnal visitors and neighbourhood pets.

All of these things can make your garden feel dreary and dull, and even reduce the lifespan of your artificial lawn. It can be difficult to choose the best method of cleaning as algae and weed removal methods for natural grass are unsuitable for artificial turf, resulting in more harm than good.

You should steer clear of pressure washing or digging your artificial grass as this could result in damaging the surface of the grass, as well as the membrane. Products containing bleach or harsh acidic chemicals should also be avoided as they can discolour your artificial lawn and cause damage to the grass and the surrounding garden.

Rain is a great cleaner for your artificial grass, but it cannot provide protection against bacterial growth problems such as algae and biofilms. So how do you tackle these contaminants on artificial lawns?

Introducing GK’s Greener Kleener for Artificial Grass

GK Greener Kleener is a powerful and effective treatment that tackles 99.9% of bacterial material. This specially-crafted formula is free from caustic acids and bleach but tough on bacterial contaminants, meaning it disinfects as it cleans, removing bacterial growth without discolouring your artificial lawn.

Fast acting and extremely effective, after just 15 minutes, the majority of bacteria will be unviable. The formula is washed away by natural weather cycles, making the whole process simple and easy to repeat whenever necessary.

Is GK Artificial Grass Cleaner Safe for Pets and the Environment?

GK Greener Kleener has a pH level of 6, which is virtually neutral, meaning there are no harmful long term effects on pets and the environment. We simply advise that you keep your pets off the treated area until it has dried, and that you put a waterproof cover over nearby plants and grass areas to prevent any brown staining on vegetation.

If any pets do come into contact with the formula before it has dried, or if you accidentally spray any vegetation, you can rinse the formula away with fresh water.

Once the treated area has dried your pets are safe to roam. The formula will evaporate naturally, and the dead bacterial matter will simply wash away in the rain, or by hose if there is little rainfall.

How to Clean your Artificial Grass with GK Greener Kleener

Weather conditions on the day of treatment need to be dry, above 8 degrees, with no rain forecast for at least 4 hours.

Sweep, brush/mechanically remove loose debris and any bulky vegetative growth from your artificial grass. Cover nearby plants and grass areas with a tarpaulin or waterproof cover (it’s safe on all hard surfaces, but may cause small areas of brown staining on vegetation).

Always wear appropriate protective clothing including gloves, safety goggles or a face visor.

Pour tap water into your preferred dispenser before adding the Greener Kleener – it is a surfactant and foams up vigorously like washing up liquid!

Greener Kleener can be applied with a garden pump sprayer, sponge, watering can, roller or brush. Simply saturate the surfaces (slightly wetting is not enough), at around 0.25 litres of mix per square metre (1 part Greener Kleener to 3 parts water), apply and leave it to evaporate naturally.

For heavy bacterial loads you may decide to brush in the material, agitating it will loosen and remove grease and grime. The dirt will be held within the suds so you may want to rinse this off, and follow up with a preventive spray as indicated above.

Is Greener Kleener Safe to Use on Other Surfaces?

You can use GK Greener Kleener to remove algae and bacterial growth from decking, sheds and fences, polytunnels, greenhouses, polycarbonates, driveways, paths and patios, metal, aluminium and plastisol cladding, caravans, headstones, animal shelters, UPVc, render, fibreglass, brick, stone, slate, marble, and all roof materials including thatch.
