Album: I think I burned tar in some olefin carpet

I got some sticky black crap on my solution hose and got lazy and didn&#039;t clean it off like an idiot.<br /> <br /> So I&#039;m doing this job today, and it&#039;s sitting on this carpet for about 1.5hrs and my customer notices a brown line on the carpet from my hose. I know, I&#039;m a dumb ass.<br /> <br /> So I used Pro&#039;s choice Power Gel (black tube), rinse, some PIG, rinse, then an alkaline liquid spotter, rinsed again.<br /> <br /> Now I just have a shaded line from it. It was originally a skinny line that looked like a burn mark, but you could tell close up that it was the black stuff from the hose.<br /> <br /> I&#039;m going back monday to work on it. <br /> I plan on pre spraying with some Matrix Olefin, do an acid rinse, then if it&#039;s still there, I&#039;m gonna spray lightly with 100% citrus Force and agitate, then rinse again. If that doesn&#039;t fix it...any ideas?
