Use a toothbrush to reach the small crevices where food particles and dirt collect. Wipe down cleaned frame with a disinfecting wipe. Soak the cup holders and snack trays in the sink, filled with hot, soapy water for about 15 mins. Rinse and dry. Clean the fabric seats and other fabric components according to the manufacturer's directions. Machine wash is applicable (for removable ones) or wipe thoroughly with damp cloth and air dry.
