[rage666]

Any one know of any products that will clean concrete from stains such as paint,oil,moss ,etc?

At the beginning of the year had some construction going on and my driveway,garage and the side of the house that had ready mix concrete got dirty due to this.the concrete is so discolored with paint ,oil,construction stains,etc that i would like to clean it.

Tried pressure washing it but its not removing the stains..
Any help/suggestions would be greatly appreciated.

Moss easy to clean with chemicals/pressure washing

Oil might be a lil tough since it soaked in, chemicals/pressurewashing might help

for the paint, meeno boy, might hadda grind that out and patch it back with concrete
