New Here

Hey all, Scott Navarro here with Navarro Window Cleaning & Power Washing. I am new here. I have cleaned windows for the past 11 years, and have been power washing siding for the past 6 years. I am in process of signing contracts and upgrading our unit to a 5.6 @ 3500 Hot Water unit, cleaning concrete for Bank drive thru lanes, and drive thru lanes for fast food joints. Anyone have any info of their experience with what chemicals to use for cleaning drive thurs and dumpster pads?? Nice to meet you all. Thanks.
