I use this every other month in my Mocha Master and use a cleaning powder on alternating months. Have been using for several years and have no problems with coffee maker. Coffee always tastes good too. I always use filtered water to make coffee and this makes a difference too Read more

I have a 5 liter countertop boiler for heating water for tea, soup, anything that needs near-boiling water. It has an electric pump in it to dispense the water, at the press of a button or by holding the container you want to dispense into against a small lever, similar to a soda fountain. The boiler tank is stainless steel, and can get a build-up of minerals on it over time, but the worst is the pump and the hose that carries the hot water to the dispenser nozzle. THAT gets clogged with minerals after a while. You can scour out the tank if you want, but there's no way to scrub out the pump and hose. For that, you need to dissolve the minerals out. I filled the tank with cold water and added a single packet of Dezcal. Even though the instructions call for a packet to treat a liter of water, it works fine in this case on five liters. This is because the descaler works on the minerals the entire time the tankful heats up. It doesn't have to just work while it's flowing from the smaller tank of a coffeepot to the spout. As it heated up, I put a big 1-liter pyrex measuring cup under the spout, and pressed the button to dispense water. The nozzle and pump inlet were very crusty with minerals, so it was a tiny trickle only...which is why I was treating it to begin with. This let some of the warm cleaner into the pump inlet, hose, and nozzle, where I let it sit another few minutes as the tank continued to heat. Every few minutes, I'd push the button to let a bit more flow through the pump, the solution in the assembly slowly eating the minerals away. By the time I could get the first liter through, the flow was almost completely restored. I poured out the first liter into the sink, replaced the cup, and ran another liter through in a few long streams. This was to make sure there was strong, hot descaler solution in the system. By the time I got the entire 5 liters pumped through, the entire thing was clean and descaled. Then I ran two full tanks of clean water through the system to remove the remaining cleaning chemical. Dezcal cleaned out the minerals in this boiler with a minimum of effort, and best of all, NO NASTY VINEGAR SMELL! I hate using vinegar to clean the coffee maker or the boiler, because the whole house smells like a pickle barrel for hours. This had no smell whatsoever! I still have three doses in the box to use when the minerals build back up again! This was effortless! Well worth the cost! Read more

This is a great product. I used it in my Moccamaster for years until I realized that Moccamasters likely contain PFAs in the black plastic parts and the company refuses to answer questions about it. So yes, it can descale a Moccamaster nicely, but I don't use one anymore. Read more

After just one use our, multiple years old, coffee maker looks almost as clean as a new one. It's easy to use too, use just dissolve one packet to one liter of water and then runt it through the coffee maker. After that the instructions tells to run three brew cycles with just water but I typically run five or six just to make sure all the chemical residue is gone before making coffee. Moccamaster, brand of our maker, recommends using a cleaning powder after descaling, which we did, but I'm not sure if that did any additional cleaning which wasn't already done by this descaler. See the attached before and after pictures for the results. Read more
