You just bought a can of Reddi Wip and are wondering if it really needs to go in the fridge before you open it. Or you have leftover Cool Whip from a recipe and are not sure if it goes back in the fridge or the freezer. Does whipped cream need to be refrigerated? The answer is different depending on which product you have.
Does all whipped cream need to be refrigerated?
The short answer: Yes for homemade whipped cream and aerosol cans like Reddi Wip, which must be refrigerated at all times. Cool Whip is the exception: it is a frozen product that lives in the freezer and only moves to the refrigerator when you are ready to use it. All three types follow the standard 2-hour rule: do not leave any whipped product at room temperature for more than 2 hours.

Key Takeaways
Homemade whipped cream: refrigerate immediately, use within 1 to 2 days
Aerosol cans (Reddi Wip): refrigerate at all times, even before opening
Cool Whip: store in the freezer; move to fridge 4 to 5 hours before use
All types: discard if left at room temperature more than 2 hours
Store aerosol cans upright; clean nozzle after every use
Does Homemade Whipped Cream Need to Be Refrigerated?
Yes, immediately and continuously. Homemade whipped cream is heavy cream with no preservatives, no stabilizers, and no protective packaging. It is one of the most perishable foods you can make. Left at room temperature, it begins to collapse and weep within an hour or two. The USDA 2-hour rule applies fully: any homemade whipped cream left out more than 2 hours should be discarded.
In the refrigerator, homemade unstabilized whipped cream holds for 1 to 2 days. Adding a stabilizer (unflavored gelatin or cornstarch) before whipping extends that to 3 to 4 days. Store it in an airtight container to prevent it from absorbing refrigerator odors, and keep it toward the back of the fridge on an interior shelf where temperatures are most stable.
Does Reddi Wip Need to Be Refrigerated Before Opening?
Yes. Reddi Wip and other aerosol whipped creams contain real dairy cream, which is perishable regardless of the pressurized packaging. The can must be refrigerated at all times, including before it is opened for the first time. You will find aerosol whipped cream in the refrigerated dairy section of the grocery store, and it belongs in your refrigerator from the moment you bring it home.
The pressurized nitrous oxide propellant inside the can limits oxygen exposure and helps preserve the cream, which is why aerosol whipped cream lasts 2 to 3 months in the fridge. But that protection only works when the can stays cold. Left at room temperature, the cream inside is subject to the same 2-hour perishable food rule as any other dairy product.
Store aerosol cans upright, not on their side. A can stored on its side can result in uneven pressure distribution, causing the propellant and cream to separate and the can to dispense poorly. Keep the can toward the back o
