This is a cleaner for the refillable K cups.
The cups I use are listed: https://www.amazon.com/gp/product/B00LHCCR92/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
Place the cup full of coffee grinds over the three cleaner blades and twist. This will remove about 95% of the coffee grinds and dump them into an empty yogurt cup (for later use in the garden).
This will avoid dumping the grands down the drain and makes cleanup much easier.
I prefer the reusable cups since i can choose the coffee I like and the is MUCH LESS EXPENSIVE.
I am including the coffee scoop I use the fill the K cups. It does not fill the cups to the rim but IMHO the coffee grinds expand when heated this allows for the expansion.
