Ah, the age old debate: should your glasses be stored right side up or facing down? However, storing glasses upside down can trap moisture, especially if the glasses aren't completely dry when stored. Storing glasses upright allows air to circulate freely inside, helping to eliminate any remaining moisture after washing. Expert consensus suggests that there is no universal way to store glasses, but rather an approach tailored to each situation. Glasses used frequently and stored in closed cupboards benefit from being placed upright to allow air to circulate and prevent stagnant moisture, while glasses or cups rarely used and stored on open shelves can be turned upside down to protect them from dust and debris.
