The common practice for storing cups in a cabinet is to place them right side up. There are a few reasons for this:
Hygiene: Placing cups right side up helps keep the inside of the cup protected from dust, debris, and potential contaminants that may be present on the cabinet shelf. It minimizes the chances of something falling into the cup and makes it easier to keep them clean.
Stability: Storing cups right side up allows for better stability when stacking them on top of each other. The cup's base provides a more solid foundation for stacking, reducing the risk of cups tipping over and potentially breaking.
Convenience: When cups are stored right side up, they are easier to grab and use directly from the cabinet without needing to flip them over first.
Drying: If you wash your cups by hand, storing them right side up allows water to drain and evaporate more effectively, leading to better drying and reducing the risk of trapped moisture that could lead to mold or mildew.
However, it's essential to consider your specific situation and cabinet design. If you have deep shelves or specialized cup racks that allow for safe storage of upside-down cups, you may choose to do so. Ultimately, the goal is to keep the cups clean, organized, and accessible.
