First, unplug the unit. Water and electricity are a terrible comedy duo, like a clown with a chainsaw. Remove the water bottle and set it aside. You’ll need to drain any remaining water from the taps into a bucket or sink. Do this for both the cold and hot water spigots. Listen for that satisfying gurgle—it’s the cooler sighing in relief.
Now, take off any removable parts: the drip tray, the nozzle covers, and the little plastic bits that always look like they belong on a spaceship. Soak these in a sink filled with warm, soapy water. Use a non-abrasive sponge—scouring pads will scratch the plastic and give bacteria new homes. You’re cleaning, not sanding a deck.
