I have a 2006 TL with the light leather (beige) interior. I had it protected at the dealer with the perma plate system but am finding that blue jeans still have started to stain the seats. I have worked with every cleaning company the protectant company and the dealer have sent out and the stains remain and continue to get darker. The solution I have been given is to replace the leather (on Perma Plates dime) but that seems to be a stupid solution since the next seat would just stain again. Has anyone had the same issue and if so is there a cleaning method anyone out ther recomends?????
