Our coffee maker looks like a rain forest inside, hours after the coffee’s finished and everything has cooled down. Every surface is wartier than a toad with big fat droplets. Is it OK to load a new paper filter and measure more ground coffee with it all wet like that, and leave it that way overnight before hitting the go button in the morning?

Seems like the paper and ground coffee would absorb liquid water, plus maybe humidity, and be a breeding ground for bad tastes or worse overnight.

I’ve been drying it out with a paper towel every day, and then leaving the lid up and the filter holding basket out for a few hours, before loading things for the next morning. But Ms. Napier says nobody does that.

What say our experts here???

Thank you!
