So i cleaned a driveway the other day and customer asks if i can give his small patio a quick once over. I cleaned it and it came up nice but there was some black spots on a few slabs so i used hypo 50/50 it got rid of quite a lot of the black spots but two of the slabs have these marks that wont shift at all. It looks like the pattern that's left when you pull ivy off a wall is it lichen ? if so do i need to use the hypo neat ?
Cheers Justin

Fossils - Chris knows because he was there when sedimentary stone was formed and the heather got caught between the layers

Carlita both you and I know Marshalls and Bradstone put them in when they make it.....so it looks authentic.
