Flasks are fantastic companions, whether for keeping your coffee hot or your water cool. But let’s face it: over time, they can develop stubborn stains and unpleasant odours, leaving us wondering “how to clean a flask properly?”. The good news? Cleaning a flask is easier than you think, and our domestic cleaning experts are here to guide you through it. Ready to restore your flask to its former glory? Let’s dive in!
How to clean a flask using vinegar and baking soda
Vinegar and baking soda—a classic duo for tackling tough stains. Here’s how you can use them to clean your flask effectively:
Step 1: Fill the flask with hot water and vinegar
Start by filling your flask halfway with hot water, then add an equal amount of white vinegar. The combination will help break down any grime or residue stuck inside.
Step 2: Let the mixture sit inside the flask
Close the flask securely and let the vinegar and water mixture sit for about 10-15 minutes. This gives the solution time to work its magic, loosening dirt and killing bacteria.
Step 3: Add baking soda
After the soaking period, add 2-3 tablespoons of baking soda into the flask. Be cautious as it will fizz! This reaction helps lift stubborn stains from the interior.
Step 4: Scrub and Rinse
Using a bottle brush, scrub the interior of the flask. Focus on areas where stains tend to linger. Once done, rinse thoroughly with clean water.
How to clean a flask using only baking soda
Don’t have vinegar on hand? No worries. Baking soda alone can work wonders too!
Step 1: Add Baking Soda and Hot Water Inside the Flask
Place 2-3 tablespoons of baking soda directly into the flask. Fill the flask with hot water, leaving a little space at the top to allow for scrubbing.
Step 2: Use a Bottle Brush to Scrub the Inside
Using a bottle brush, scrub the flask’s interior. Baking soda is a gentle abrasive, perfect for removing residue without damaging your flask’s surface.
Step 3: Rinse and Dry
Once scrubbed, rinse the flask thoroughly with warm water. Dry it upside down on a dish rack to ensure no water is left behind.
How to clean a flask using denture tablets
Denture tablets—an unexpected hero in your cleaning arsenal. They’re designed to remove odours and stains, making them ideal for flasks.
Step 1: Fill the Flask with Water and Denture Tablets
Fill your flask with warm water and drop in 1-2 denture tablets, depending on the size of your flask.
Step 2: Let the Tablets Dissolve Inside the Flask
Allow the tablets to dissolve completely and let the solution sit for at least 15-20 minutes. The fizzing action works to break down residue and neutralise odours.
Step 3: Rinse the Flask Thoroughly
Pour out the solution and rinse your flask several times with clean water. Ensure no tablet residue is left behind, and dry the flask completely.
Best practices for cleaning a flask
Want to keep your flask sparkling clean for the long haul? Follow these best practices:
Making Sure to Brush the Inside of the Flask
No matter how thorough you are, some grime can only be removed with a bit of elbow grease. Use a brush to scrub every nook and cranny.
Use a Bottle or Hip Flask Brush
Invest in a good bottle brush or hip flask brush. These are designed to reach the tight corners of your flask, ensuring a deep clean.
Ensure the Flask is Cleaned Inside
Rinse your flask thoroughly after each use. Even if it’s just water, bacteria and odours can build up over time.
Avoid using bleach on stainless steel flasks
Bleach might seem like a quick fix, but it’s a big no-no for stainless steel flasks.
Opt for Gentle Cleaning Methods
Harsh chemicals like bleach can corrode the stainless steel lining of your flask, reducing its lifespan. Stick to gentle, natural cleaners like baking soda and vinegar.
Pro tip: Always rinse your flask thoroughly after cleaning. Residual cleaning agents can affect the taste of your drinks and may even pose a health risk.
