One of our commercial power washing clients is a Chick-fil-A. Cold and wet kept us from pressure washing this drive thru at night this past week. We were able to take our heat unit down there and properly power wash those grease stains and tire marks away in the drive thru. Power washing the back dock sure made it look like new. After completing the dumpster pad area, you couldn't even tell someone spilled grease there since we last cleaned.
