Whether heading to the gym or the office, your thermosteel flask remains a constant companion.

But since you use it almost daily, cleaning and maintaining its hygiene is crucial to avoid unnecessary illnesses. Here's how to go about it.

How To Clean A Flask Bottle: 4 Ways To Clean A Flask Bottle

Flask bottles are generally airtight, making them vulnerable to trapping moisture, foul smell, and stains. Cleaning them is not just necessary for health reasons, but also for preserving their efficiency and extending their lifespan. If you are unsure how to do it, find a detailed guide below:

1) Daily Rinse

If you don't want leftover residue to affect your beverage's taste or give rise to bacterial growth, it is imperative to clean your flash daily. This way, your flask will remain fresh and free from any odour. Simply swirl it with warm water and pour out dry.

2) Use Warm Water-Mild Soap

If you want to go deep with a daily rinse, use a mild dish soap and warm water. A few drops of that dish soap inside your flask, along with warm water, and a gentle shake will leave your flask spick and span.

3) Baking Soda for Tough Odour, Stains

Using baking soda will remove those persistent stains or foul smell from your flask bottle since it is a natural cleaner. To employ this method, add 1-2tbps of baking soda to your flask and load it with warm water. After 30 minutes, use a gentle scrub to clean the interiors of your bottle, paying special attention to the corners. To get rid of any baking soda residue, give a thorough rinse with clean water.

4) Want Deep Cleaning? White Vinegar At Your Service

White vinegar is the other useful cleaning agent that removes odour from your flask. For this, mix vinegar and warm water in equal parts and pour it into the flask bottle. Let it sit for 60 minutes, after which, cleanse deeply with normal water. Give it another wash to remove any persisting vinegar smell.

Some Additional Tips To Clean Your Flask Bottle

Apart from the ones mentioned, remember not to put your flask inside the dishwasher since high heat can impact its vacuum seal. Given below are 4 additional tips:

1) Separate Cleaning For Lid

To note, the flask's lid collects grime, in seals and crevices. To remove that, use a soap-water combination and scrub with a toothbrush or sponge. If your flask has a rubber seal, clean it separately to prevent mold buildup.

2) No Harsh Scrubbing

Absolutely avoid harsh chemicals or abrasive scrubbers since they have the potential to cause damage to the stainless-steel surface or impact insulation properties.

3) Complete Air Dry

Post cleaning, leave your flask open and let it be bone dry. This is to prevent any buildup of moisture and avoid mold or unpleasant odors.

4) No Carbonated Beverages

Carbonated beverages can damage your flask bottle's seal. Hence, never store it in your thermosteel flask.
