How do I clean and maintain the Graco Slimfit 3-in-1 car seat?

The removable seat pad can be machine washed cold on a delicate cycle and hung to dry—do not use bleach or harsh detergents. Buckles and harness straps should be wiped with a damp cloth only; do not immerse buckles in water or use lubricants. Removable cup holders can be washed with mild soap and water. Store the car seat in a cool, dry place away from direct sunlight.
