Artificial grass is better than natural grass. It provides a better aesthetic value when installed in your garden. Aside from that, artificial grass is easy to maintain and comes with a guarantee that it will last long. Fake grass is susceptible to natural elements that destroy real grass. One such natural element is mould growing on the grass. But when garden owners fail to install fake grass properly, mould can grow on it. If you notice mould growth on your grass, you can remove it. So, how do I get mould off artificial grass? 

Mould vs Artificial Grass

Makers of synthetic grass make it resist mould and other natural elements. In fact, your fake grass will last longer and offer value for the money after you install it. At times, due to lack of proper installation and upkeep, fake grass can develop mould growth. Although mould will not destroy your grass easily, it will create an unpleasant situation that will prevent you from enjoying your activities on the grass. If garden owners fail to provide proper drainage on the artificial grass, water will settle on one part. That part will eventually become damp. Mould and mildew are attracted to damp or moist environment, where they thrive quickly. 

Lack of hygiene or not cleaning your fake grass regularly can create the perfect condition for mould growth. Decaying food and other organic matters can make mould thrive on synthetic grass. Other conditions that can cause mould growth is laying your artificial grass on concrete or decking without preparing the base. Not preparing a good base for your artificial grass will cause drainage issues, and eventually, mould will grow on damp parts of your fake grass. If you discover mould on your synthetic grass, don’t panic; perform these simple tasks:

  • Rinse down the grass,
  • Apply artificial grass cleaner,
  • Brush down the grass, and
  • Rinse the grass again.

Steps to Treat Mould on Artificial Grass

Garden owners that discover mould on their artificial grass should not panic; this is because the solution is much easier than they think. Garden owners have to follow these simple steps to remove mould from your fake grass surface. After, garden owners can take further steps to prevent future mould growth on their fake turf. 

Step One – Rinse Down the Grass

You have to rinse down your fake grass with a hose or a pressure washer before you apply the treatment on your fake grass. But before that, garden owners must first clean their artificial grass to remove the source of mould growth. If you discover that the source of mould growth is decaying materials on your grass, you should sweep it off immediately. You can use a broom to sweep spoilt food, leaves, twigs, and other decaying organic materials that are left on the grass. 

After that, you can rinse the surface of your fake grass in preparation for treatment. Note that when using a power washer on your fake grass, you should not lower the machine’s tip so that it is too close to the grass, as this can peel the blade. Place the tip some inches away from your fake grass and reduce the pressure when using a pressure washer to wash your synthetic grass. 

Step Two – Apply Treatment

After giving your artificial grass the first wash, you should start treating it. You can do this by applying artificial grass cleaner to the spots that are affected by mould. You can ask your fake grass supplier to recommend any cleaner that you can use on the grass. Ensure that you utilize an environmentally friendly cleaner and won’t peel the colour of your synthetic grass. After getting the right artificial grass cleaner, you can dilute it and spray it on the affected areas. 

Step Three – Brush Down the Grass

Now, you have sprayed the cleaner on your fake grass; the next thing is to acquire a good brush and give it a good scrub. Use a soft brush and apply gentle pressure when scrubbing the surface of your artificial grass. Ensure that you don’t remove the blades of the grass in the process. 

Step Four – Rinse Away

After getting all traces of mould off your artificial grass, you can rinse the cleaner and other dirt away. And rinse thoroughly!
