I have found that using Simpple Green and Woolite mixed in warm water with a stiff brush will do one hell of a cleaning job on your interior. Then use a leather lotion/ conditioner on all leather/ vinyl. Since my vette is covered during the bad weather months, sit a box of Arm @ Hammer Baking soda on the floor to absorbe any moisture. also Dryer sheets in the cargo area to keep it fresh.:cool:
