Drew Frohn, a wholesale manager and coffee educator for Coava Coffee Roasters, once told HuffPost that a good cup of coffee starts with water quality. That’s important to know, considering that coffee is 98% water. However, it doesn’t matter how filtered your water is: Over time, your coffee maker can get a layer of limescale (or build up of calcium carbonate) caked onto its insides and parts, whether that’s a brew basket, Keurig, coffee pot, Chemex, Nespresso machine or even your favorite mug. That’s no bueno when you want that perfect cup of Joe, as it’ll affect flavor and your coffee maker’s brew efficiency.
When soap and water won’t work (or reach!), take care of it with a descaler. This liquid substance dissolves limescale with as little effort as a regular brew cycle. We found an eight-use supply that one reviewer says easily gets “so much gunk out” of your favorite coffee maker, and right now, it’s 15% off its typical price!
If you’ve been dissatisfied with the quality of your coffee lately, consider the fact that it may not you, the beans, your measurements or water. It could just be your machine’s cleanliness.
Take it from one reviewer who swears Active’s descaler made for a better tasting coffee. “I have had my Keurig for at least 10 years and have NEVER cleaned it EVER (I didn’t know I had to do this lol),” they explain, “and I can definitely say the coffee takes so much better now! It was amazing how much junk came through with this process! Will definitely continue to use monthly now that I know how great coffee should taste.”
This coffee cleaning liquid is 15% off, but not for long, so nab your cleaning supplies for less while you can. (Pro tip: You can save even more with Amazon’s subscribe and save!) Keep reading to see testimonials from other happy coffee drinkers.
“I read the positive reviews and decided to order, and I am SOLD on this cleaner! I ran it through my old Nespresso Citiz machine, and it worked great. I could not believe the gunk and gross stuff that came out of my machine during the cleaning process. The liquid is very easy to use, just pour with some water and run a few cycles through. I will be more likely to keep up with my espresso machine maintenance since it’s a no-brainer to use this stuff. I also noticed my espresso tasted a lot better after I cleaned the machine. Great product and excellent purchase!” — VegasLou
“If you have a Nespresso VertuoPlus coffee machine then hopefully you know what I’m talking about when it comes to their descaling and regular cleaning system. I recommend watching a video on YouTube by “the fiX files” named “Nespresso Vertuo Plus Descaling How To” to use the descaling system if you no longer have the manual (or you can find the manual online). I did use the wrong cleaning system and used the regular cleaning system instead of the descaling system on accident but other than that this thing works! I was scared at first because some of the reviews were saying it messed up their machine but this really cleaned the inside of my Nespresso VertuoPlus machine with no problem. The first session really got the gunk out that my machine couldn’t do by itself without the cleaning solution. First, the water was dark 🤢 (more than the video actually shows) and now the water is clear without any sort of leftover coffee tint! I’m so happy! I recommend! Oh, and one more thing, it also made my spout shoot out the liquids more efficiently after it was fully done cleaning 👍🏼” — J.H.
“Use this product & you’ll taste the difference in your coffee! So satisfying to see all the gunk leave my coffee machine! After one full cycle you can see the difference in the water.” — Jessica
“Our expensive 18-month-old coffee maker recently started behaving badly, finishing its cycle before the water tan was empty. Before that, I’d noticed the quality of the brewed coffee had deteriorated. The manufacturer’s website said descaling would both solve the premature completion and the decreased coffee quality. (It explained that scale reduces the machine’s ability to heat the water, resulting in weaker coffee and slower brewing) Wow! They were not kidding. The descaling worked instantly - reversing the problem of unused water. It was clear that the two rinse cycles ran through the machine faster than our machine had run in a while. This morning’s first pot of coffee tastes so much better than yesterday’s that I felt compelled to write a review. I had spent a lot of time researching coffee machines before buying this unit, finding a model that met the Specialty Coffee Association’s high standards but that didn’t break the bank. Water temperature is crucial, this industry group says. It clearly is. After my success with this product, I encourage everyone to buy it, use it, and keep a regular schedule of descaling your machine!” — J. Vincent
Own a Keurig or coffee pod machine? Check out these reusable baskets that’ll actually make a difference in your brew cycleand help cut down on waste.
A reusable mesh ground coffee filter for K-Duo machines (25% off)
If you have a K-Duo, you have options: a pot of ground coffee or a single-serve pod. The problem is, the pot portion uses paper filters like a traditional coffee maker, thus causing more waste alongside those plastic pods. Never buy a filter (or single-use K-cup) again. Instead, opt for this reusable coffee filter pack. It comes with a mesh filter that fits the coffee carafe of a K-Duo or K-Duo Essentials machine perfectly, and when you're done, just rinse it clean. It's 25% off for a limited time.
Keurig's reusable K-cup
If you're a brand purist, you'll want to grab Keurig's own reusable K-cup that works in all Keurig home brewers. It can go in the dishwasher and has a multi-stream filter on top, ensuring you get the best flavors and aromas from your favorite coffee beans. Note: You'll need to take the "pod holder" out of your machine before you put this in, and reviewers advise that you carefully read the directions to make sure you're popping and locking everything correctly.
A trio of reusable coffee pods and an exact scoop
Again, the biggest issue with Keurig machines is the waste that they create with single-use plastics. Curb the need to toss your coffee pods into a landfill with this reusable K-cup pack instead. This three-pack is a universal pod that works with the K-Duo, K-Classic, K-Elite, K-Select and K-Cafe coffee brewers. Plus, it comes with a nifty scoop so you know exactly how much ground coffee to load into each cup. These cups are dishwasher-safe, too!
