If your vacuum flask doesn't smell as good as it used to, we've got simple tricks to fix that. Let's explore easy ways to kick out those bad odors and keep your flask ready for tasty sips and bites.

Find the Problem

First, figure out what's making your flask smell. Sometimes, old food bits or not cleaning well can cause the stink.

Give it a Good Wash

Clean your flask really well. Use warm, soapy water with a sponge or brush. Pay attention to the lid and stopper – those places can hide smells.

Baking Soda Trick 

Baking soda is like magic for smells. Fill your flask with warm water and a spoon of baking soda. Let it sit for a few hours or overnight. Then, wash it out well. This helps get rid of bad smells.

Citrus Zest Boost

Citrus fruits, like lemons or oranges, are great for killing smells. Cut them into slices, put them in your flask with warm water, and let it sit for a while. Then, wash it out. Your flask will smell fresh with a hint of citrus.

Vinegar Fix

White vinegar is a smell fighter. Mix equal parts vinegar and water, pour it into your flask, and let it sit for a couple of hours. Rinse it really well to get rid of the vinegar smell.

Denture Tablet Magic

Drop a denture tablet into your flask filled with warm water. Let it fizz and work its magic for a couple of hours. The effervescence of denture tablets can help break down and remove stubborn odors.

These easy tips will make your vacuum flask smell good again. Just keep it clean and use simple tricks like baking soda, citrus fruits, vinegar, and denture tablets.

Say goodbye to bad smells and enjoy your drinks and meals without any surprises!
