Expired Listerine: still ok?
Find a bottle of Listerine in my old man's cabinet. It has been opened but been used a little only. When I look at the expiry date... May 2003 :bulging: :wow: It smells the same, tastes the same... just do not know if it kill the gems like the same.
I am not a dentist / chemist and I understand there is a reason for a expiry date. However, I believe Listerine is antiseptic mouthwash. If it has been kept away from the sunlight, provided that nobody has put in any foreign substance, I am confident it is no more / less harmful than when it is new.
What do you think?
