When it somes to cleaning leather seats...there must be some type of chemical imbalance in my brain that is preventing me from doing this correctly. I have tried Lexol, Gliptones leather cleaner, and Woolite. I have seen some improvements in my seats (that are light gray in a 2001 Lincoln LS), but I can't seem to get all of the dirt out. The Woolite has worked wonders on my vinyl door panels, but when it comes to my seats, I seem to be underperforming. I have used terry cloth towels, scrub brushes, toothbrushes to apply the cleaner on the seats. Have I become a victim of unreasonable expectations, or do I just need to apply more elbow grease??? Please help me out!!! Does anyone have a routine to clean seats that is tried and true??? If so, please share the wisdom. Thanx.
