Everyone, I'm new to the pressure washing business and after a few months of preparation and research I think I am ready to do my first house (mine of course). I will be using Steve's Citracleen housewash mix but have a quesiton regarding a soot stain caused by the exhause of my propane stove. Any thoughts on what I should use for this? I was thinking scrubbing some Gutter Shock if the Citracleen doesn't work. Thanks, Lance Mountain Home & Window Service
