Mayonnaise, made from eggs, is highly perishable and should not be left out. After use, transfer it to a clean jar or bag, seal or tie it tightly, and store it in the refrigerator. This method will preserve the flavor of mayonnaise for an extended period.
2 Tomato Sauce
Once opened, tomato sauce can be kept for up to a month. However, if you wish to extend its shelf life without any adverse effects, store it in the refrigerator.
3 Seed Oils
Oils derived from seeds, such as walnut and almond oils, should be stored in the refrigerator to prevent them from turning rancid. Additionally, this storage method will ensure that their flavor remains unchanged over time.

Mustard can be stored outside, but its shelf life will be very short. Instead, store it in your refrigerator, and it will last for up to a year. Moreover, refrigeration will perfectly preserve the flavor of mustard.
5 Maple Syrup
Maple syrup is derived from the sap of maple trees. It is susceptible to mold growth if left at room temperature. Therefore, store it in the refrigerator for extended freshness.
Spices also have a limited shelf life. Some last only a few days, months, or years, while others can be kept indefinitely if properly stored.
