I'm about curious what product you like to use when you come across soot from furnace or propane vents that are venting out the side of a structure. I've run into this a few times with some house cleanings on vinyl siding. House mix cleans it up a little but not completely. I have F9 and one restore on the truck. I wondering if you guys use any other products that work good with this situation or recommend anything else because I'm concerned after cleaning it with the chem I got, that it will stick out just as much as the soot.
