Its an Acura MDX, spilled in the very back on carpet and under back seat. I went out there today and used 1)carpet cleaner, 2)then chased it with a wet bruch and all purpose cleaner to suds it up, 3)then wiped with clean towel, 4)then went over with extractor, 5)then wet scrubbed again and wiped up with clean dry towel and went over with vacuum to get the rest of the water up til dry. I couldnt smell the weed killer any more after I was done, I think I got ammuned to the smell. But my client went out and said she couldnt smell the weed killer anymore. I will find out tomorrow if that took care of the smell.
