If you are looking to protect it from any future damage (assuming you are referring to TEXtile (cloth) interior), give all the fabric a thorough vacuum as you have not had it long enough to really get them dirty and use a fabric protectant such as 303 Fabric Guard. This will essentially waterproof the fabric portion of the interior and prevent any stains or dirt from even touching the fabric fibers and will help you keep them like new. I would apply two layers of it as that will give you the best coverage and will keep the interior spill and dirt resistant for 6 months at least.
