The drip tray? That’s where coffee and tears accumulate (not really, but close). Scrub it with soap and a brush, then rinse. Wipe down the outside of the cooler with a damp cloth—yes, even the top where dust bunnies gather.
Reassemble everything once dry. Put the bottle back on, plug it in, and wait five minutes. Then pour a glass—admire that sparkling, silent delivery of perfection. You did this. You are a cooler-cleaning rockstar.

If you see white, crusty bits (like desert fossils), that’s hard water scale. Don’t panic! Soak a cloth in pure vinegar and wrap it around the spigot for twenty minutes. Then scrub gently—they’ll dissolve like magic. Science is cool, literally.
For extra credit, run one more vinegar-through-water cycle if you have an electric cooler. Your machine will purr like a happy cat.
