Clean Your Vacuum Thermoflask without using any Chemicals:

Things you need:

  1. Thermoflask
  2. 5-6 large chunks of ice or ice cubes
  3. Sea-salt/large grained salt
  4. Hot water

Step 1:

First step into cleaning your Thermoflask is to put the large chunks of ice into the Thermoflask. You have to be careful not to let the ice melt before your actual work is done.

Step 2:

After putting your the ice cubes, immediately add the sea salt/coarse salt to the flask. Depending on your size of your Thermoflask, add the required salt. If you don’t have sea salt, fine salt will do the task too. If you use fine salt add another teaspoon of fine salt to it, so that it will effectively work like the sea salt.

Step 3:

With the ice cubes and salts inside the Thermoflask, close the lid and it’s time to shake the flask vigorously so that the ice cubes and sea salt rubs against the wall of the thermoflask and helps it to scrub off the stains on the wall of the Thermoflask. Do this till the ice melts away. If the stains don’t go away at once, repeat the steps again.

Step 4:

This is the last step. Pour out the ice and salt and wash the Thermoflask with Hot water. Check for any leftover salts and wash it thoroughly with hot water. Your Thermoflask is squeaky clean and ready to use again!
