To clean a wine cooler like the EdgeStar TWR215ESS, the first step is to switch it off and unplug it. Next, you’ll want to open it up and remove all the removable parts like shelves, as well as the bottles of wine. Make use of a mild cleaning solution like warm soapy water or simply warm water on its own to clean the interior surfaces, and then wash any wire shelves or trays with a gentle detergent solution. If you have wooden shelves, these should be cleaned with a specialized wood cleaning product, and you can clean the outside of the cooler with a mild detergent and the glass door with some glass cleaner.
