The BabyBumper can be cleaned using a warm damp soapy cloth or sponge. Blot the soiled areas and let stand to air dry on its own. Do not place the BabyBumper in the dryer or use other devices such as a hair dryer. Please keep out of direct sunlight, foam will turn yellow and may become brittle if left exposed for an extended period. During long term storage, ensure the devices lay flat in an air controlled environment and are not folded or bent. Do not stack objects on top of the BabyBumper while being stored.
