I just did that to my car the other day. I washed it with Turtle Wax car wash. Vaccumed all the floor mats and underneath. Then i detailed the interior...I used Armorall vinyl cleaner (the spray kinda sucks it leaves marks) then i cleaned the inner part of the windows...put some leather cleaner all over the seats. Then i went onto waxing with with Mothers. Then i went a little extreme and took off each wheel and cleaned it back and front then sprayed some tire wet then mounted em back on. I love seein the effects after it all, it just looks so damn clean! Oh and the newspaper and windex works great too but special window cleaner is always a plus!
