I tried some Lexol, Meguiars leather cleaner, and Woolite with a toothbrush, terrycloth, and horse hair brush and nothing would touch my explorer seats. I just got it 3k miles ago and the first thing I noticed when opening the door at the dealer was how dirty the leather was even after their "detail". I finally tried a magic eraser and the results should speak for themselves. I need to finish it now and condition them again. I did this last night in the dark and took it to get an oil change and had to explain what was wrong with the seat, lol. I also just now (while grilling out) did a 50/50 of my wifes seats. 52k miles and never cleaned other than wiped. Thank God I found this site! However, she likes them better shiny she says, lol.
