We did a pretty big Ash removal in a front yard last week. We precariously lowered a lot of stuff that was over the driveway to avoid cracking the concrete. We did, however, put some brown and green scuffs in it from dragging branches. The HO called me yesterday and was somewhat upset about it. I guess you can't please everybody but I do want to make it right with him. I haven't ever had someone complain about this before. Just wondering if you guys have had any experience with this and what's the best way to get the scuffs out? A hose, scrubber brush, and simple green??
