what do you guys use / do to keep your Marquis cloth interiors clean ? My interior is nice and clean and i want to maintain it that way. please suggest products etc.

also i noticed that everytime i get in the car with my kids in the back and we drive somewhere, when we get there i have to press the door unlock button so my kids can open their doors. any way to keep their doors from locking automatically ? thanks .

i have some more questions but i forget them right now.
