Yep, that's how I roll. Keurig Dunkin Kcup, filtered water, bungeed to the top of the fridge, under the microwave in a 2020 Freightliner Cascadia.
There for a second I thought you were prepping for a medical procedure.Did the "Big Flush" last night.
Cleaned the carafe, lid, and basket with Urnex Cafiza. Came out squeaky clean.
Ran 3 brew cycles with citric acid in warm water. Calcium clogged the filter the first 2 pots. Third pot still showed some but clean enough for me. 3 clear water flushes.
Brewed some of the Peruvian microlot this morning..... Impressive what a difference a clean brewer and carafe makes in the taste.
Still using the Bonavita BV-1900 TD brewer I got from goodwill.
