Pressure Washing Artificial Grass? Read this first…

One of the main reasons people change from real grass to artificial grass is because it’s advertised as the maintenance-free solution. But that’s not strictly true, artificial grass needs much less maintenance than real grass, but it does need maintaining. Leaves, dirt, debris, animal poop, and birds mess all need to be removed from artificial grass.

It’s not so bad in the winter months when the weather helps out by rinsing the astroturf on a daily basis. But during the hot dry summers, you’ll need to get busy, especially if you have pets. Dogs and cats will treat the fake grass just like real grass and it will soon start to smell if you don’t take some action. Obviously, you’ll be removing solid wastes every day but the liquid can cause strong smells very quickly.

Can You Use A Pressure Washer On Artificial Grass?

We get asked this question quite often and the answer’s not that straight forward, you see it all depends on how your artificial grass is seated. If it’s bedded on sand you might want to leave the pressure washer in the shed, because the sand will easily get dislodged and cause lumps and bumps in your lawn. The correct way to install artificial grass is by using a granite chipping base, covered with granite dust, covered by a weed membrane.

The granite base is much more able to withstand water pressure making it the ideal sub-base for artificial grass. As long as you use the correct nozzle and PSi, pressure washing artificial grass is the quickest and easiest way to keep it looking and smelling great.

So it depends on how the artificial grass is bedded, if it’s bedded on sand don’t use a pressure washer. If it’s bedded on granite chips it’s fine to use a pressure washer.
