Ever wonder what’s lurking inside your coffeemaker or espresso machine? We thought not. Even the most exotic gourmet free-trade coffee beans will turn bitter when filtered through residual coffee oils, minerals, and lime deposits. Yeah, we all know we should clean the equipment every so often, but vinegar stinks up the kitchen, takes forever, and can leave a “salady” aftertaste to your next brew. Now there’s a new line of products that descale, remove oils—and even mold—from the machine, and also help maintain the burrs and motor inside a grinder. Full Circle coffee and espresso equipment cleaners, $9.95 each at Williams-Sonoma stores.
