If you own one of the best Keurig coffee makers, you'll need to know how to descale a Keurig. Not only will this maintain its super freshness and flavor, but will ensure your Keurig coffee maker is in top condition, and lasts longer.
Regardless of your model, it's recommended that you should descale a Keurig every three to six months. Keurig, of course, advises using its descaling solution or liquid for best results, but we reckon that you could go for a more general descaler if you want to save some cash. And for the best clean, be sure to follow the quantities of solution to water as described on your product.
There are different approaches based on the type of coffee maker that you’ve picked for your kitchen. Here, we are going to talk you through how to keep yours brewing coffee that tastes as fresh as the day you bought it.

- To perform the cleansing cycle, lift and lower the handle, making sure to select the biggest brew size.
- Repeat this process until the ADD WATER alert is illuminated.
