How Long Does Pepper Spray Last?

Pepper spray is a powerful self-defense tool, but it doesn’t last forever. Whether you own a canister for personal safety or security purposes, it’s important to understand its expiration date, effectiveness, and storage requirements to ensure it works when you need it most.

⏳ Pepper Spray Shelf Life: Does It Expire?

Most pepper sprays have a shelf life of 2 to 5 years, depending on the brand and formulation. Over time, the propellant inside can lose pressure, making the spray less effective.

How to Check If Your Pepper Spray Is Still Good

✔ Test your spray – A brief spray (outdoors, downwind) can confirm it still works.

✔ Check for leaks or clogs – A damaged canister may not function properly.

Proper Storage & Maintenance for Maximum Effectiveness

To ensure your pepper spray remains potent:
