How to remove grass stains from patio

Hello all,
I had new turf laid 4 weeks ago and it has grown well..... too well. Not the perfect conditions today as still a little wet but had to cut it. It was 6 inches !!!!!!. Problem is its stain the Indian stone patio where I walked. Any advice on how to remove stains ?

Thanks so much

 

Ahh, its the small edging stones that border the grass/patio and the stone paving nearest the grass. I could hose it down but there is a risk it will get on the new turn especially if I try to scrub the edging stones

 

Thanks fat controller, I will give that one a try tomorrow.
