If you’ve ever owned a Hydro Flask, you know how amazing it is. It keeps your drinks cold for 24 hours, keeps the sun out of your eyes, and comes with a lifetime warranty.
A few months ago, though, I realized that my Hydro Flask lid had a strange smell and mold was growing inside it! I was so upset, but then I learned that all Hydro Flasks are prone to this issue.
Don’t worry; we’re here to help with some cleaning tips to eliminate the smell and make your Hydro Flask lid as good as new!
To ensure that your Hydro Flask lid is clean and ready for use, follow these steps:
If you’ve ever noticed a funky smell from your drinking straw, it’s probably because your hydro flask lid is silicone. Silicone is a porous material and can absorb odors if not cleaned properly.
If you want to keep your hydro flask straw smelling fresh and clean, you’ll need to give it some attention occasionally. Luckily, cleaning the silicone lid is easy! The smell of your hydro flask straw lid can be removed with baking soda and vinegar. These two items work together to remove the smell from your hydro flask straw lid:
As you can imagine, the best way to clean your Hydro Flask lid will depend on what it’s made of.
The standard offering is food-grade 18/8 stainless steel, which means that the best way to clean a Hydro Flask is by using hot water and dish soap, with no worries if you’re worried about scratching the interior surface.
If your bottle has a colored exterior, like blue, pink, or black, then using hot water and soap might not suit those colors. Try using warm water and very little soap—you don’t want to risk damaging any finish or paint!
You can use a straw brush to clean a Hydro Flask straw lid. This will ensure you get all the residues off your cover. It will also make sure that there are no scratches on your lid which would affect its ability to keep drinks hot or cold.
Afterward, you can use dish soap and hot water to get in and ensure everything is clean. You can also use a bottle brush to get some serious cleaning done!
Straw brushes are inexpensive and can be found at most grocery stores, convenience stores, coffee shops, and gas stations.
If you’re looking for a more thorough cleaning and want something to help prevent buildup from happening again, consider using a straw cleaning kit with a scrubber or brush attachment.
To remove mold on your Hydro Flask, it is best to use a soft bristle brush to remove all visible mold. After that, wash the lid with hot soapy water and let it air dry.
Also, you can try to get mold out of a Hydro Flask with baking soda and water:
You can also try using a bottle brush to clean the exterior of your hydro flask.
When cleaning your hydro flask lid, ensure you’re doing it right. Different pieces must be removed for proper cleaning, including the straw lid and the top.
Below are instructions on removing your hydro flask straw lid and preparing it for good scrubbing.
If your straw is broken, you’ll first want to remove the lid from your Hydro Flask. Then, use a cleaning cloth or paper towel to wipe down dirt inside the lid and around the rim.
Next, remove your hydro flask lid to clean out its pieces separately. To do this:
Next, clean your straw with soap and hot water until all debris is removed.
Be careful not to break any pieces off while cleaning; if you’re worried about breaking something off, then soak everything in soapy water for an hour or two until all of the debris is gone, and then give them one last scrubbing with warm water before rinsing them out thoroughly in cold water again to make sure they’re clean enough for reassembly!
The first step is to remove the straw from your lid. To do so, flip over your lid and use a fingernail or something sharp to pry it out. It should pop right out when you get it started with a little bit of force.
Once that’s done, give the inside of your straw a good scrubbing with soap and warm water until all debris is removed.
No, the lid is designed to be leakproof. The only way for water to get into your hydro flask is to leave it open and allow air in.
If you fill it up with ice and put it in the freezer, condensation might be outside your bottle, but that’s not leakage. It’s just moisture from freezing ice rubbing against plastic.
It is recommended that you wash your Hydro Flask lid once a week. This will keep it from smelling and prevent mold from growing inside your hydro flask. The lack of airflow in the cover can cause these things to happen over time.
If you don’t clean your hydro flask regularly, there may be some buildup between the lip and body of your water bottle that needs cleaning out before use (which is why we recommend cleaning it weekly).
If you follow these steps, your Hydro Flask lid will be clean and ready for use. It’s important to avoid using soap on the interior of your Hydro Flask as it may leave a residue behind. If something gets stuck inside, try boiling water or baking soda before scrubbing with soap again to remove any residue after cleaning with just water alone!
