Sterilizing Baby Food Weaning Utensils

Hi! Due to a lack of space, i have been using my avent sterilizer & dryer to dry my baby’s food weaning utensils & freezer trays etc, and sterilize it at the same time. Am just thinking, is it safe to do so though? Will it cause the materials to degrade etc? Most of the utensils I use have said that it is dishwasher friendly….
