Only Harders Tropical Slush Mixes should be used in slush machines. Regular Harders syrup is not formulated to freeze in a slush machine and will, over time, damage the motor and mixer due to over freezing. Harders Tropical Freeze mixes are packed with more flavor than regular syrup and will give you an optimal slush texture and flavor.

How to make slush:
Pour 1 part slush mix into the slush machine.
Pour 4 parts water into the slush machine.
Follow your specific slush machine's instructions on start-up and maintenance.
