I have a heavy duty oil stain on the seat that I can't remove on a client's Ford King Ranch truck. It is a work truck so I believe it's a hydraulic oil stain if that matters. I tried APC, degreaser, CG leather cleaner with terry cloth and a boar's hair brush with minor improvement. First time dealing with this leather and will listen to any advice.
