But just because Keurigs make coffee convenient doesn't mean they don't need maintenance. When the single-serve device isn't regularly cleaned, you invite mold into its crevices, which may be toxic to consume or negatively affect the flavor of your brew. By avoiding this common Keurig mistake, you not only get the best-tasting product possible, but you can also extend the life of your machine.
Bamboo is a natural, porous material. When it remains damp - especially in an enclosed space like its plastic packaging - it can retain moisture and warmth, thus creating the ideal, humid environment for mold to grow and thrive. The mold can also seep into the pores of the whisk, rendering it unusable. "Bamboo whisks need to be air-dried," Choe explains, "so it should be left out."
