2. Carafe needs more attention than the reservoir The part you should be most worried about cleaning is the pot, Perry said — which can throw off the taste of your cup. asserted

Coffee stains can especially build up in insulated carafes that can't be seen. asserted

Perry → think → coffee
Water matters more than you think For homes with hard water, mineral buildup can gradually affect the machine's performance and, ultimately, the taste of home-brewed coffee. asserted
buildup → matter → coffee

Perry → build → film
"I would absolutely make sure you’re wiping that out with a dry paper towel. asserted
you → make → towel
Get the coffee oils off of it," she said. asserted
she → get → it

smell → tip → you
"It’s not that fresh coffee smell, it’s that old coffee smell," she said. asserted
she → ’ → ?

they → add → Perry
"Your freezer is actually a better preservative," she said. asserted
