Will stinger mouthwash still work after an hour?

Yes, Stinger mouthwash will still be effective after an hour, but its efficacy may diminish over time. Mouthwash is designed to provide antibacterial and freshening benefits shortly after use, but prolonged exposure to saliva and other factors can reduce its active ingredients. For optimal results, it's best to use it as directed and avoid rinsing your mouth with water immediately afterward.
