When opened, Aquasure will dry out in the tube if not stored properly. Avoid contact with moisture. Push the contents towards the neck of the tube. Clean any excess and close tightly. Store in a dry place. To extend its lifespan, place the product in a bag in the refrigerator. Leave it at room temperature for 6 hours before use. At low temperatures, unused Aquasure will harden in the tube. To restore it to its original state or to facilitate its flow, dip the tube in warm water for 15 minutes or hold it with warm hands until it softens.
