Patio cleaning

[LIZS]

Pressure washing or chemicals ? Which is the more eco-friendly or relatively less damaging/wasteful?

anyone ?

I bought some stuff at the garden centre which said it was okay for wildlife

you just brush it on with water

we got it so that next door's dogs wouldn't have a problem with the terrifying chemicals that my mother had provided

I can't remember what it was called tho and I am no mood to go out to the shed sorry!
