I've got a rather large commercial job coming up in which we'll be doing concrete sidewalks several hundred feet away from the pressure washer. Due to gum spots, I plan to use hot water, however, the way in which the sidewalks weave in and about the area, I think it would be very difficult to keep the hose on a hard surface at all times. Is there a temperature at which the gum will still come off relatively easy yet not cause damage to the grass from prolonged heat exposure? Hopefully someone has some real world experience with this.

Thank you,

Ben
