First of all, it would be greatly appreciated if the directions on the descale bottle were correct!!!! I wasted an entire bottle because the directions do not tell you to put the coffee maker in descale mode, nor do they tell you such a thing exists! The directions that came with the coffee maker also do not provide instructions.
I found the directions on YouTube (How to descale Keurig K Supreme Plus Coffee Maker by Just a 
Dad).
I will call customer service to request a replacement bottle. 
Otherwise, the kit hardly deserves a drumroll for
required maintenance.
