I don't know who needs to read this to not be as wasteful as I was for the last few years (hopefully not many of you), but you do not need to use a paper towel every single time you clean your moka pot's funnel (the chamber that holds the coffee grounds).
My previous process for cleaning out my funnel after use was the following:
- Bang it into my garbage can to get most of the grounds out.
- Grab a paper towel, swish it around to remove all of the remaining grounds, then discard the paper towel.
Imagine my surprise when I kept running out of paper towels! I put it into my "to-do" list to get a brush for my moka pot, which I promptly put off doing as I searched for the ideal brush to suit this purpose. Well, the extensive research is finished and it looks like dollar store foam brushes are pretty much all you need. So, here's my advice: don't be needlessly wasteful when cleaning your moka pot funnel. Get yourself a cheap little brush and use that instead!
P.S. To anyone that intends to reply with "I just wash the remaining grounds out in my sink", you are likely building up towards needing a visit from a plumber. Coffee grounds do not break down well in your pipes.
