Method 4 of 4: Ice and salt

  1. Fill the thermos about ¼ full of ice (smaller cubes work best) and add 2 to 3 tablespoons salt.
  2. and shake. The ice and salt are scrubbing away at the side walls as you shake so by twisting and turning the thermos, you’ll gradually wear away all gunk.
  3. Discard and rinse. This works, but it takes a fair amount of effort….. and ice.
