Meguiars makes really good stuff. The NXT interior protectant works great. If you are wanting to clean vents, heater/ac controls radio and stuff like that black magic makes a good kit that is like $10-$15 and it has 3 different brushes in it that makes interior easy. As far a the dash itself i use the microfiber towels because they actually hold the dust and dirt rather than moving it around.
