Had it a year with no scratches. I'm pretty careful with the interior of the truck as is and only use a swiffer duster to clean the interior and the Ford supplied Navigation lens cloth to wipe it down. I don't like the look of other cleaners and what they do to the interior. If I need to clean a spill (like coffee or something) off the interior plastic I just use a damp microfiber or damp rag and clean it up. I don't see the need to spend extra money on "interior detail spray" when all we have is plastic for panels.
You'd be surprised how much grime builds up on the seats over time. I use a leather cleaner to clean it up now and then. Usually water and microfiber does it though. But I use the cleaner before I add a conditioner. Mostly for UV protection on the dash.
