Instructions:

1. Prepare the Thermos:

- Empty the thermos and remove all loose grounds or liquids.

- Ensure that the thermos is completely cool before starting the cleaning process.

2. Prepare the Bleach Solution:

- In a well-ventilated area, put on safety goggles and gloves to protect yourself.

- Mix a solution of 1 part bleach to 10 parts water (e.g., 1/2 cup of bleach to 5 cups of water) in a large bowl or sink.

3. Submerge the Thermos:

- Place the thermos upside down in the bleach solution.

- Ensure that the entire inner surface of the thermos is submerged, including the spout and any crevices.

4. Let It Soak:

- Let the thermos soak in the bleach solution for approximately 30 minutes.

- This will help disinfect and remove any stubborn stains or residues.

5. Rinse Thoroughly:

- After 30 minutes, remove the thermos from the bleach solution and rinse it thoroughly with warm water.

- Be sure to rinse the spout and all surfaces multiple times to remove any remaining bleach residue.

6. Neutralize with Baking Soda:

- Create a paste by mixing baking soda with water.

- Apply this paste to the inside of the thermos and scrub gently with a non-abrasive sponge or cloth.

- This step will help neutralize any residual bleach and remove any lingering odors.

7. Rinse Again:

- Rinse the thermos thoroughly with warm water to remove the baking soda paste.

- Ensure that there are no traces of baking soda left inside.

8. Air Dry:

- Place the thermos upside down on a drying rack or clean kitchen towel to air dry completely.

- Allow it to dry thoroughly before using it again.

Important Notes:

- Never mix bleach with other cleaning agents, such as ammonia or vinegar, as it can produce harmful fumes.

- Bleach can damage certain materials, so it's essential to check the manufacturer's instructions for your thermos before using bleach.

- Always wear safety goggles and gloves when working with bleach to avoid skin and eye contact.

- Ensure the thermos is well-ventilated while soaking in the bleach solution.
