Yes Grass King artificial grass is very easy to clean. If you discover any stains on your artificial grass, including animal waste, use warm water and washing up liquid along with a stiff brush to remove them and just hose off when finished. For more tricky oil-based marks, you can easily remove them either using a weak bleach to water solution (1:100) or you can even use white spirits and a cloth – please ensure you test these on a small sample patch first to check this is suitable. Make sure you always hose off detergents or cleaning fluids when finished.
