I am a neat freak with my Fusion SEL V6. I use Meguires for the leather to clean and condition about once a week. Use Mequires on the interior plastics also. I wash the car once a week with Maguuires car soaps, I vacuum once a week. For those with the black leather interior, I highly recommend you get your windows tinted. I had to. It was too hot!! Huge difference in interior temp and besides.. Looks smooth and sharp... 8). Detail tires/wheels too....
