How to clean a soft flask

by | Cleaning

In this post, you will learn how to clean your soft flask so that you won’t be disgusted looking into its nooks and crannies. I run around 1 800 miles per year, so my Salomon soft flasks are used a lot. Thanks to that, I have figured out a quick and easy way to deep clean soft flasks.

The most important rule to keep your soft flask clean and fresh is to wash it after every use as soon as possible. As you probably know, the longer your drink stays in the flask, the dirtier the flask gets, and the more the smell lingers in it, especially if you forget it in a vest for a couple of days. If you are wondering how to clean a soft flask the best and most effective way here is a step by step guide.

 

How to clean a soft flask

  1. Unscrew the cap.
  2. Fill the flask with warm water.
  3. Use a soft brush to clean the inside of the flask. If the flask is very dirty, add some baking soda to scrape the dirt away.
  4. Take the cap and unscrew the seethrough silicone tip (called the soft valve).
  5. Push out the gray plastic part with, e.g., a pencil. Make sure to push from the side you drink from.
  6. Clean all three parts with a thin brush or, e.g., a pencil or a screwdriver covered with a cloth.
  7. Let all three parts air dry.
  8. To dry the flask, hang it on a line with a clothespin.
  9. Put everything back together.

And that’s it! You have a deep cleaned soft flask ready for your next adventure.

IMPORTANT!
In case you don’t clean the silicone tip of the valve (the soft valve) after every use, the gunk will eat into the silicone, and you will not be able to clean it. So make sure to wash it every time. In case your tip has gone bad, you will likely need to replace the whole flask.

Even though you can clean the soft flask with a pencil and a cloth, it is not ideal. If you want to make the cleaning process easier, check out our recommended brush sets at the following Amazon links.

 

Smelly soft flask?

In case you forgot your soft flask in a vest, chances are it can get smelly and funky tasting even after you’ve cleaned them. If dish soap and brush doesn’t do the job, the next step to get rid of the funky aftertaste and smell is to use cleaning tablets. Great options are Bottle Bright or denture cleaner tablets such as POLIDENT® 3 MINUTE DENTURE CLEANSER, which many people report works even better at a fraction of a cost!

In case you are a DIY type of person, you can prepare a solution of peroxide oxide, citric acid, and soda bicarbonate and use it instead.
