Hydro Flasks are great bottle options to store both cold drinks and hot drinks. Since they can store different types of drinks it is important that they are cleaned regularly and properly. 

Although some may use them solely for drinking water, it is vital that they are cleaned carefully between uses.

How To Clean Hydro Flask Straw Lid

This is because bacteria and mold grow on water and other liquids that are left standing. 

If you are the owner of a Hydro Flask with a straw lid, then it is essential that you clean it properly.

The straw lid of a Hydro Flask is a place where bacteria and mold are more likely to grow since the liquid can get stuck in the straw. 

In this guide, we are going to walk you through how to thoroughly clean the Hydro Flask straw lid. This includes before you first use the Hydro Flask and after each use. 

Cleaning Straw Lid Before First Use

Before you use your Hydro Flask, it is always important to wash them. This allows any germs and bacteria that might be on the Hydro Flask to be removed before you start using it.

Also, there is a possibility that your Hydro Flask bottle became dirty during transit, so cleaning it ensures you are using a fresh and clean Hydro Flask bottle. 

For the first clean of your Hydro Flask bottle, it only needs a simple clean.

It is highly recommended that you dismantle the Hydro Flask bottle and soak all of the parts in some warm soapy water for a few minutes. 

Then rinse out the bottle and lid. Dry the bottle before you use it. 

Everyday Clean Of Straw Lid

As mentioned before, it is incredibly important to clean the straw lid of your Hydro Flask bottle. This is due to the fact that the lid is prone to having mold grow on it.

This is especially the case if you use your Hydro Flask to hold drinks other than water. 

To maintain a clean Hydro Flask straw lid you should clean it after every use but also deep clean it at least once a week.

This will prevent anything from building up in your Hydro Flask straw lid. 

So how do you clean a Hydro Flask straw lid? Well, the process is very similar to how you would clean the bottle. Except you have to properly disassemble the straw lid.

This means removing the straw from the lid. To do this, you just need to pull the straw until it pops off.

It is essential to separate these two parts so you can properly clean all of the surfaces of the lid and the straw. 

Once everything is disassembled, you need to get a bottle brush for both the straw and the lid. The brushes for the straws are often called pipe cleaners. 

How you clean the lid, depends on the type of straw lid you have.

If you have the screw-in straw lid, then when you are cleaning you need to pay particular attention to the grooves in the screw part. 

To clean the lid and the straw, it is best to use warm water and soap for everyday cleaning. With your bottle brush, you need to use the warm soapy water mixture and scrub the lid.

Pay close attention to the spout on the lid as this is where mold grows. Thoroughly scrub the lid with the brush. 

To clean the straw, you also need to use warm soapy water. Take the straw and wash it in warm soapy water. Then take the pipe cleaner and scrub the inside of the straw with it.

The pipe cleaner brush helps to remove any debris from the straw.

To keep the straw clean, make sure you push the pipe cleaner through the entire straw so anything stuck in the straw falls out the end of it. 

Once you have finished using the brushes to clean the straw and lid, rinse them with clean water.

This is to make sure there is no soap left in the straw and the lid as it can cause soap residue to build up. 

Let the straw and the Hydro Flask bottle lid completely dry before assembling.

If you assemble them when they are wet, the water can get trapped. This will cause bacteria to grow. 

If your Hydro Flask straw lid has a rubber gasket, then you need to remove this before cleaning.

A lot of dirt becomes trapped under the rubber.

Disinfecting The Straw

If you haven’t cleaned your straw lid of the Hydro Flask bottle in some time, then it would be a good idea to disinfect the straw lid.

When you disinfect the straw lid, you want to avoid using harsh chemicals such as bleach because they can damage the lid. 

Instead, you should do a regular clean of the straw lid, but before you let it dry you should wash it with white distilled water vinegar.

The vinegar kills and removes any bacteria that might be spreading on your Hydro Flask straw lid. 

To do this, make sure the straw and lid are separate.

Then you need to use the lid brushes and dip them into the vinegar. Scrub the straw and lid with the vinegar for a few minutes.

After, rinse the lid and straw before you let it dry.  

Are Hydro Flask Straw Lids Dishwasher Safe?

Some Hydro Flask straw lids are dishwasher safe. Many choose to separate the straw and the lid and place them in the dishwasher.

However, it is not recommended you do this regularly as it can damage the seal on the lid. 

Final Thoughts

Washing the straw lid of your Hydro Flask bottle is a simple job but requires paying attention to the details in your lid.

It is extremely important to wash the lid and straw of your Hydro Flask as this is the most common place for bacteria and mold to grow. 

We hope this guide has helped you understand how to clean your Hydro Flask straw lid. Thank you for reading!
