9 Non-Food Items You Should Always Keep in The Fridge

When we think of our refrigerators, we often only consider food and beverages. However, many non-food items benefit from being stored in cooler temperatures. Here’s a list of surprising things you should keep in your fridge to maintain their potency, extend shelf life, or preserve their effectiveness.

1. Organic and Homemade Cosmetics

Refrigeration can help preserve the potency of organic and homemade cosmetics.1 The cold temperature slows the degradation process of natural ingredients, ensuring the products last longer. It’s particularly beneficial for skincare serums like retinoids and vitamin C serums, which are sensitive to heat and light. Keeping these items cool inhibits bacterial growth, making your beauty regimen safer and more effective.

If you have leftover seeds from gardening, store them in your refrigerator to preserve their viability for the next planting season. Place them in an airtight container with uncooked rice at the bottom to absorb excess moisture. This method ensures your seeds remain fresh and ready for planting .

Batteries such as NiMH, NiCad, and Zinc-carbon perform better when stored in cold temperatures. Keeping them in an airtight container in your refrigerator reduces their self-discharge rate, extending their shelf life. Just remember to bring them back to room temperature before use .

4. Nail Polish

Storing nail polish in the refrigerator prevents it from separating and thickening.2 The cold temperature maintains the polish’s consistency and color, ensuring a smooth application. Keep the bottles upright and tightly closed, and allow the polish to rest for about 30 minutes before use .

5. Flowers

Fresh-cut flowers can last longer when stored in the refrigerator. The cool environment slows the aging process and limits light and heat exposure, which causes flowers to wilt. Most florists use this method to preserve flowers overnight. Store your bouquet in a vase with water, and you can enjoy fresh flowers for up to 14 days .

6. Baking Powder and Baking Soda
