Cleaning your Chemex coffee maker is an essential task to maintain its optimal performance and ensure the purest flavors in every cup.

Whether you’re a seasoned Chemex enthusiast or a new owner looking for guidance, this comprehensive guide will walk you through the step-by-step process of cleaning your Chemex.

From basic maintenance to deep cleaning techniques, we’ve got you covered. Discover the secrets to keeping your Chemex sparkling clean and ready to brew that perfect cup of coffee. Let’s dive in!

The Importance of Daily Cleaning for a Pristine Chemex

Keeping your Chemex coffee maker clean on a daily basis is essential for preserving its quality and functionality.

Regular cleaning not only ensures the removal of bacteria buildup but also contributes to the longevity of your Chemex.

Fortunately, the cleaning process is straightforward and can easily be incorporated into your daily coffee routine.

Thoroughly cleaning your Chemex after each use is the most crucial step in preventing the accumulation of bacteria.

Once you have finished brewing, begin by discarding the residual coffee grounds and rinsing the Chemex with warm or hot water.

Take a moment to swirl the water in the base for about a minute, ensuring that any remaining particles are flushed out.

If needed, use a sponge with soap to clean the exterior of the Chemex, remembering to remove the wooden collar and rawhide tie before doing so. After cleaning, allow the Chemex to air dry naturally.

By following this daily cleaning routine and avoiding the habit of leaving coffee sitting in your Chemex for extended periods, you can significantly reduce the need for deep cleaning.

In fact, with consistent daily cleaning, a deep clean may only be necessary once a year. Many Chemex users have reported minimal or no buildup even with daily use, even after several months of ownership.

Make daily cleaning a habit to ensure that your Chemex remains in pristine condition and consistently delivers the finest coffee flavors.

With proper maintenance, your Chemex will continue to provide exceptional brewing experiences for years to come.

The 8 Best Methods for Cleaning a Chemex

Hot Rinse: A Simple Flush

The hot rinse technique provides a quick and easy way to clean your Chemex.

Start by pouring hot water into the carafe and swirling it around for a minute or two.

This simple process effectively flushes out any residual coffee, preventing the taste from being altered or impaired in subsequent brews.

Soap and Water: Effective and Easy

One of the most straightforward and efficient methods for cleaning a Chemex involves using soap, water, and a brush.

After each use, rinse or wash the Chemex with soap and water.

If there’s a significant buildup, soaking it in white vinegar can help break down the deposits.

White Vinegar and Water: Loosening Bacteria and Oil Buildup

For a more thorough cleaning, combine equal parts distilled white vinegar and warm water in the carafe, filling it to the brim.

Let your Chemex soak for 30 minutes. This mixture effectively loosens any bacteria and oil buildup.

Afterward, empty the vinegar solution, scrub with a bristle brush, rinse thoroughly, and allow it to air dry.

Baking Soda and Water: Breaking Down Oils

To tackle oil buildup in the Chemex base, add warm water until it reaches just under the base, and then add baking soda.

Swirl the mixture around for a few minutes, ensuring that the baking soda breaks down the oils.

Rinse the Chemex thoroughly with water.

Ice, Salt, and Dish Soap: An Invigorating Cleanse

For a refreshing cleanse, pour ice, table salt, and liquid dish soap into the Chemex.

Fill it with water and swirl the mixture for a minute or two.

Rinse the Chemex thoroughly with water, ensuring all traces of the solution are removed.

Ice, Lemon, and Salt: Sparkling Freshness

Create a rejuvenating mixture by adding ice to your Chemex until the bottom half of the carafe is halfway full.

Combine a tablespoon of salt and a tablespoon of lemon juice.

Swirl the mixture for up to 15 minutes or allow it to sit until the ice mostly melts, then swirl for a minute or two.

Afterward, empty the mixture, rinse the Chemex and let it air dry.

Use a Dishwasher: Convenience at Your Discretion

While most Chemex models are dishwasher safe, it’s important to exercise caution.

Before loading it into the dishwasher, remove the collar and tie to prevent any potential damage.

Although a dishwasher can leave your Chemex squeaky clean, it’s advisable to check the manufacturer’s instructions for specific guidance.

The Chemex Way: Manufacturer’s Recommendations

Chemex offers its own cleaning solution and a specialized brittle brush designed specifically for their product.

Follow the instructions provided with the cleaning solution for optimal results.

Keep in mind that these recommended products may not be the most budget-friendly option for everyone.

Remember to remove the wooden handle before cleaning your Chemex.

Regularly rinsing or washing it with soap and water after each use, and using white vinegar for stubborn buildup, will ensure the longevity of your Chemex while consistently delivering great-tasting coffee.


Can I clean my Chemex in the dishwasher?

Yes, most Chemex models are dishwasher-safe. However, it is crucial to remove the collar and tie before placing it in the dishwasher to avoid any potential damage.

How often should I clean my Chemex?

It is recommended to rinse or wash your Chemex with soap and water after each use.

Additionally, if there is significant buildup, soaking it in white vinegar can help remove the deposits. Regular cleaning will ensure optimal performance and taste.

Can I use baking soda to clean my Chemex?

Yes, baking soda is a great option for breaking down oil buildup in your Chemex base. Simply add warm water just under the base, add baking soda, swirl the mixture, and rinse thoroughly with water.

What’s the best type of brush for cleaning my Chemex?

The ideal Chemex cleaning brush is a bottle brush with soft bristles and a long handle.

This type of brush is highly recommended for effectively and safely cleaning your Chemex.

Its soft bristles are gentle enough to prevent any potential damage to the glass, while the long handle provides convenience and ease of use.

Using a soft-bristled bottle brush will ensure a thorough cleaning experience for your Chemex.

Can you use a Chemex filter twice?

No, it is not advisable to reuse Chemex filters.

The specially designed Chemex bonded paper filters are intended for single-use only when brewing a single batch of coffee in your Chemex coffee maker.

Reusing the filters can lead to clogging with fines from the initial brewing, resulting in slower flow during subsequent brews.

If you’re looking to save money, consider investing in a reusable Chemex coffee filter that can be washed and reused multiple times, providing a cost-effective and sustainable alternative.

What is the best way to dry a Chemex?

The best way to dry a Chemex after washing it with warm water and a few drops of liquid soap is to turn it upside down and allow it to air dry.

By turning the Chemex upside down, any excess water can naturally drain out, and the remaining moisture will evaporate more effectively.

This method ensures thorough drying without the need for additional steps or materials.
