I have a classic Keurig. Lately whenever I make coffee it comes out tasting like dirt. I’ve cleaned all the parts, including the needles. I’ve done the descaling with water and vinegar. I go to make coffee and the first time it tastes fine, but then it goes back to tasting like dirt. I’ve been careful about not leaving k cups in after I use them. Has anyone else experienced this? And any thoughts on how to resolve. Thanks!
