Cucumbers should be stored in the refrigerator, ideally in the crisper drawer with other vegetables but not fruit, to keep them fresh for about two weeks. Before storing, it's recommended to wash cucumbers in a vinegar solution (ΒΌ cup of 5% distilled white vinegar mixed with 10 cups of cool water) to eliminate mold spores and bacteria, then dry them completely. English cucumbers or those wrapped in plastic should have the plastic removed before storage. For sliced cucumbers, storing them in a sealed container like a mason jar with the skin on helps them last 7 to 10 days. Using a paper towel in the container can help control moisture for whole or cocktail cucumbers, which can last 2 to 3 weeks this way. Avoid excess moisture to prevent spoilage, and if cucumbers are wrapped in plastic or stored in sealed bags, removing or replacing wrapping prevents moisture buildup and mold formation.
