How to Unclog Metal Coffee Filter

The process of making coffee can be a rather satisfying one. However, if some things are not taken care of properly, you will likely not get the taste you desire. And one of those things that you need have an eye on is the coffee filter you are using, especially if it’s a metal one.

Metal coffee filters are revolutionary. They save a lot of money, as you can reuse them. More and more people are getting into these types of filters.

As they are reusable, you need to clean them properly at a regular interval to ensure the coffee’s quality. And that is exactly our topic of discussion today – how to unclog metal coffee filters.

3 Ways of Cleaning a Metal Coffee Filter

There are a few ways to unclog that filter of yours and we will be talking about 3 such most efficient ways. Namely:

  1. Using baking soda
  2. Using vinegar
  3. Using vinegar + baking soda

Let’s jump right into the processes

Cleaning with Baking Soda

As you may know, baking soda is an alkaline substance. And alkaline substances are outstanding in cleaning metals. As such, baking soda turns out to be quite a good choice for cleaning those metal filters you use.

In order to unclog the filter, you will need to follow the process below.

  1. Wash the filter normally and look for any stains that can be removed easily.
  2. Take a bowl of warm soapy water and dip the filter in it.
  3. Make sure the filter is in place for a few minutes, maybe just about 15 minutes.
  4. Pick it up and clean it with a soft brush of any sort, could even be a toothbrush with soft bristles.
  5. Now comes the soda part. Take a very little amount of baking soda and sprinkle it on the bristles of your brush. In the meantime, start gently rubbing over the filter in order to take out whatever stains are left, no matter how small or large they may be.
  6. After cleaning it with soda, then take it to a sink where you will take it to a second wash with warm water, but not with soap, and leave it to dry after.

There you have it. Now you can use your metal coffee filter once again.

Cleaning with Vinegar

It is important to understand that vinegar is an acidic liquid. In addition, this is a very good substance to use for cleaning metals as well, much like soda.

How to go about cleaning your filter with vinegar –

  1. Mix warm water and vinegar together to form a solution. There should be the same amount of water and vinegar in the mixture.
  2. When the solution is ready and still warm, dip the filter in the solution. Leave the filter in the solution for approximately ten minutes.
  3. Immediately after picking up the filter from the solution, you should use a brush with soft bristles to give it a final rub down.
  4. You need to wash it again with non-soapy warm water and then let it dry. When the metal coffee filter has dried, you will be able to use it again as a coffee filter.

We have finished discussing two of the ways of cleaning a metal coffee filter.

Now comes the 3rd option – using both vinegar and soda.

Using Vinegar + Baking Soda

This process is also as simple as the last two. Let’s learn.

  1. First of all, you will need to prepare a solution that is made up of vinegar, warm water, and baking soda.
  2. You will need to submerge your filter for a period of time and then pick it up.
  3. For the final touch, use a brush to scrub the surface
  4. After it has dried, you can put it to use again.

Voila! Your filter is as good as new.


Cleaning your coffee filter is necessary for both health and taste reasons. And you should also be gentle in your cleaning so as not to damage the filter.

Although you cannot deep-clean the reusable coffee filter very often, you should at least wash it with warm water after every use. That is sure to ensure good taste later.
