Wash

• Wash your mugs with dish soap and warm water to ensure cleanliness. Remove all traces of dirt and debris from the mugs and dry with a clean towel. Check the glass to ensure all fibers and dirt are removed.
  
  

Wet

• Wet the mugs with water and place them directly into the freezer. Leave space between multiple glass mugs because they can shatter if bumped against each other.
  
  

Wait

• Leave the mugs in the freezer until they are completely covered with frost, which usually takes an hour or longer.
  
  

Serve

• Serve the beverage in the frosted mug immediately after removing the mugs from the freezer. Keep your beverage in the fridge before serving to ensure it is frosty-cold.
