Ithas worked fantastically, but gradually clogged up over time. I've washed it with warm water and dish soap multiple times to no avail. Anyone have cleaning tips? Or do I just have to buy a new filter?

This problem seems quite normal. Over time, the little holes are filled up with small coffee grounds and stuck there by the help of gluing force of grease. This grease is extracted during brewing process.


As for the to other options, These acids are food, so they are safe to use. You may leave the filter in these for a while. Apart from that, you may try alcohol, but check whether it damages the filter.


I would advise against using soap to clean anything coffee related. As a simple measure, just use boiling water to loosen the oils. You can also use citric acid (the recommended cleaner for coffee machines), you can find it online pretty cheap. Another option would be to soak it in baking soda to dissolve the oils. Whatever you use, just make sure you rinse it thoroughly afterwards.


The only thing that I've found that I've found that works elegantly, quickly, and completely is ultrasonic cleaning. After boiling with vinegar water, lots of rubbing and scrubbing, high pressure steaming, and even ten minutes in a pressure cooker, it seemed to only get a bit more clogged. I set it in a small inexpensive ultrasonic cleaner I received as a gift and the stubborn oils and sediment trapped gave up the ghost immediately.


I tried boiling in vinegar and washing in the dishwasher over my bottle jets the other day. It did improve the flow situation greatly, but the filter was still brown. So I ordered urnex coffee equipment cleaning powder off amazon and two days later my filters are like new. I just boiled my cone filters and added a teaspoon of the powder.


While some may advise you not to wash your Chemex, I found that to be false. If you start to notice a cloudy residue or are a heavy user, a once or twice yearly deep cleaning is probably in order. This will ensure a consistent brew and well-balanced coffee every time.


In a similar way to how you clean other kitchenware, such as cups and plates, you will need to invest in specialist brushes that will fit through the narrow, central segment of the flask. But make sure the handle is plastic or wood to avoid scratching or, worse, breaking your Chemex.


Bottle cleaning brushes are widely available, low cost and can make cleaning your Chemex a lot easier. They tend to consist of bristles attached to a thin, malleable piece of metal that allows the bush to bend while cleaning, maneuvering through hard-to-reach areas.


While you do this, the ice should rub against the walls of the flask, scrubbing oils and leftover coffee residue from its walls. The salt will also act as a mild abrasive, further helping to remove coffee stains.


Simply fill your Chemex to the brim with equal parts white vinegar and water. Leave it to stand for thirty to forty minutes. For really tough oil stains or mineral buildup, an overnight soaking may be in order.


Once again, pour out the liquid and fill again with warm soapy water. You may want to move your Chemex in a swirling motion to allow the mixture to rub against its edges. Rinse thoroughly to remove any last remnants of vigar.


Touted as a game-changer in the world of portable espresso makers, the compact Staresso Classic SP-200 promises to deliver that rich, creamy shot every coffee aficionado dreams of. But does it live up to the hype?


So, make sure there is no residual coffee in the Chemex. Then pour your ice, salt, and liquid dish soap. Mix it up together. Next, fill up your Chemex about 1/3 the way up with water and swirl. Keep swirling!


You will find a nice healthy froth will start to develop. As you swirl, the ice, salt, and dish soap will start to gently scrub the coffee oils and residue off the glass. If your Chemex is really in need of deep cleaning, you will want to swirl for a minute or two longer.




I first discovered Chemex on Instagram, perusing other food bloggers feeds several years ago. I kept seeing this gorgeous beaker-like thing with a stunning wood handle filled with coffee and I had to figure out what it was. Well, clearly I was late to the party as Chemex has been around for more than 70 years.


What really makes Chemex special and distinguishes it from other brands are the filters. Chemex filters are 20-30% thicker than regular coffee filters which filters out bitterness, oils and grounds. That means you get a super clean and clear cup of coffee.


Based on my research (from the coffee gurus), it seems a medium to medium-coarse grind works best. When you grind your coffee to this consistency, it should resemble the texture of sea salt. If you grind your coffee too fine, it will take longer for your coffee to brew given the increased thickness of the Chemex filters.

I meant to mention something re cleaning. I rinse my Chemex with water after each use but no soap. About once a month or whenever I notice any staining, I fill the pot with 1/4-1/3 white vinegar and remaining to the brim with hot water and let it sit for an hour or more and then rinse. This works similar to descaling a coffee maker. At any rate, an option to soap.


Hello,

I enjoyed reading this after I saw this article because you have presented some good points. Everything has represented in a pretty good way. Thanks a lot for sharing your amazing tips and guides about coffee brewing. It helped me a lot. Keep sharing.


Having watch a half dozen videos of measuring, timing and algebraic functions just to get a cup of coffee almost put me off of the idea of a pour over; your Chemex video brought it back down to Earth for me. Whew!


I have set myself a little challenge. I want to learn how to use all of the major coffee brewers by the end of 2020. I have a list in my mind of those I want to learn. I started the year learning the Kalita Wave, then I moved onto the V60. My next choice to try out was the Chemex, the world-famous coffee maker designed by Dr. Peter Schlumbaum, a German inventor who moved to the U.S. due to their favourable patent laws. The Chemex is known for its iconic and clever design, so much so that the device is stored in the Museum of Modern Art in New York City.


My Chemex arrived this morning along with a box of filter papers. The box of filter papers was taller and almost as wide as the box that my V60 came in a few weeks ago. Chemex filters are big. The Chemex itself came in a tall box, and I could hardly wait to open it up. Upon opening the box and inspecting the device, I realised I would need to give it a quick clean before the first use (which I have done with every brewing device thus far).


After cleaning, the Chemex was ready to go. I waited a bit after getting the device and then I brewed my first cup. My first observation when brewing was that the filter papers, when unfolded, are much larger than I expected. I knew the filters were big but in the Chemex they look even bigger, presumably because they are unfolded. I followed the instructions and lay the side of the filter with three layers of paper over the spout to prevent blockages. Like the V60, I had to rinse the paper to make sure it stuck to the brewing device.


I used my now-standard continuous pour V60 recipe to brew on the Chemex. I bloomed the coffee for 30 seconds, stirred, and then poured in the rest of the water in one single pour. Well, I tried to pour the water in one pour. I am used to pouring close to the top of the brewer, which is easy on the V60 and the Kalita because the filter paper is a lot smaller. I had to pour from quite a height in my Chemex which meant I was pouring a lot faster than I usually would. I tried to slow down but often the stream of water broke, which I have read is not desirable in continuous pouring techniques.


Despite the pouring troubles, I managed to pour in around the right amount of water (with a bit extra, by accident). I was happy I did not go over my target more than I did because I was focusing more on pouring than looking at my scale. I was in a different position than I usually am when brewing with a pour-over so that I could see the entire bed of coffee, unobstructed by the filter. I may adjust this technique after I have made a few more coffees.


Before I got the Chemex, I had heard that the brew times were much longer. This turned out to be true. My brew time was around four minutes, much longer than the two minutes or so that it takes my V60 to brew, or the three minutes or so it takes for me to brew a Kalita Wave. With that said, my coffee was not over-extracted: the final cup tasted delicious. I did not mind the longer brew time because it was a pleasure to watch the coffee brew. The sun was shining outside which meant a lot of natural light was present in the room, which felt great.


Chemex is a range of quality products for commercial cleaning, sanitising and disinfecting. The formulations are specially designed for housekeeping, food service, food manufacturing, hand care, laundry and a range of specialist applications.


With coffee, however, overtime you can develop really really serious stains. There's practically no way to avoid it. If you have any carafe-style drip machine (especially if there is a heating plate involved), where coffee is sitting at least in the bottom, sometimes for days, you are inviting some serious stains. At times, I've attacked these with steel wool and some serious elbow grease, only to realize that I could never quite get it clean enough. When I finally worked in a commercial setting, however, the solution became clear: you have to use something special. Unsurprisingly, it comes from the espresso-saturated land of Italy, where keeping your macchina incontaminato is very important. You can buy Urnex tablets for coffee makers, espresso machines, or in other formats, but it really does have a huge effect on getting coffee stains off of class and metal.
