Camel Flask Care Guide: Clean It Right, Use It Longer

When choosing a vacuum flask, most people focus on its insulation performance. But the truth is, the lifespan and function of your flask depend largely on how well you care for it. With a high-quality brand like Camel, proper cleaning and maintenance not only extend its life, but also ensure your beverages stay fresh, safe, and flavorful.

In this guide, we’ll walk you through how to clean and maintain your Camel flask—inside and out—so it stays just like new, day after day.

Why Does a Flask Need Regular Maintenance?

Many people assume that simply rinsing with water is enough. However, without proper daily care, your flask can develop bacteria, unpleasant odors, or even blockages—especially if you often fill it with coffee, tea, or juice. These drinks can leave behind stains or smells on the inner liner and stopper.

To keep your Camel flask performing at its best, regular maintenance is essential.

Basic Structure of a Camel Flask

A Camel vacuum flask typically consists of the following parts:

• Inner liner (usually made of stainless steel or glass, provides heat/cold retention)
  
  
• Stopper (ensures tight sealing and prevents leaks)
  
  
• Spout (controls pouring flow, prone to residue build-up)
  
  

Each part requires a different cleaning method to maintain hygiene and performance.

Daily Cleaning Routine

After each use, follow these basic steps to prevent residue buildup:

• Empty any remaining liquid and rinse the inner liner with warm water right away.
  
  
• Mix a small amount of mild detergent with warm water and pour it into the flask. Clean the interior using a soft bottle brush or sponge. Avoid metal brushes, as they may damage the glass liner and affect the flask’s safety and insulation.
  
  
• Rinse thoroughly with clean water to remove any soap residue.
  
  

Weekly Deep Cleaning Routine

A weekly deep clean helps prevent odors and stains:

• Disassemble all parts of the flask, including the stopper and spout, and clean each piece separately to avoid dirt buildup in small areas.
  
  
• Add 1 tablespoon of baking soda or lemon juice into warm water and fill the flask. Let sit for about 30 minutes.
  
  
• Use a bottle brush to gently scrub the bottom and sides of the inner liner.
  
  
• Rinse thoroughly with warm water, drain upside down, and allow everything to air dry before reassembling.
  
  

How to Properly Clean the Stopper and Spout

The stopper and spout are the most likely areas to accumulate residue and require special attention:

• Remove them weekly and soak in warm water with a small amount of detergent for about 15 minutes.
  
  
• Use a soft toothbrush or a small brush to carefully scrub gaps and inner surfaces.
  
  
• Rinse thoroughly and dry before reassembling the flask.
  
  

Removing Stubborn Stains or Odors

If your flask develops stains or persistent odors, try the following:

Baking Soda + Lemon Juice Method
Mix 1 tablespoon of baking soda with the juice of half a lemon, pour into the flask, then fill with warm water. Let sit for 20–30 minutes. Rinse thoroughly with clean water. This method removes odors and leaves a fresh scent.

Cleaning Tablets
Specially formulated bottle-cleaning tablets are available on the market. They are effective for removing lingering odors and stains and are easy to use.

Proper Drying and Storage

Proper drying after cleaning is essential, as moisture inside the liner can lead to bacterial or mold growth:

• After cleaning, drain the flask upside down to air dry completely before sealing it with the stopper.
  
  
• If storing the flask for a long time, keep the stopper slightly open to allow ventilation.
  
  

What to Avoid When Caring for Your Flask

To ensure your flask lasts longer, take note of the following:

• Avoid sudden temperature changes. Do not add ice water or ice cubes right after pouring in boiling water. This could cause the glass liner to crack. Pre-warm with hot water before use.
  
  
• Avoid external impact or shaking. The glass liner is fragile and may break if dropped or hit.
  
  
• Do not use metal utensils or brushes for cleaning. These may scratch or damage the interior surface, reducing performance or causing breakage.
  
  
• Do not soak the entire flask in water for long periods, especially the cap and bottom. This may affect its lifespan or cleaning results.
  
  

Common Flask Issues and Solutions

Leaking
Most commonly caused by an improperly sealed stopper or a worn-out gasket. Check and replace the gasket if damaged.

Stained Inner Liner
Often caused by coffee or tea residue. Soak with baking soda and warm water to restore.

Glass Liner Cracks
Usually caused by extreme temperature change or impact. In such cases, please visit our repair department to replace the glass liner.

Persistent Odors
Use a white vinegar solution or cleaning tablets to soak and remove odors before rinsing thoroughly.
