Bunn | Ultra-2 HP Black, Manual Fill - Cleaning Card: Cleaning Instructions

Great tasting coffee relies on multiple factors, and one of them is a clean machine. Diffusers often accumulate old and burnt-on coffee which affects the flavour in the coffee-making process, making it sour, bitter or metallic in taste. Instead of letting your coffee machine build up in grime and dirt, regularly cleaning it each night after a day’s work will help regulate the build-up.
