Testing expired hand sanitizer for effectiveness can be a practical step before deciding to discard it. One simple method is to check the alcohol content, which should be around 60-70% to ensure it’s still effective against germs. You can use an alcohol meter or even perform a flame test, though caution is advised. If the sanitizer still smells strongly of alcohol, it might still be viable. However, if it smells off or the consistency has changed, it’s probably time to replace it. To maintain hygiene, consider using Hand Sanitiser Dispensers that track usage, helping ensure you’re always using effective sanitizer.
