Yes, even if it freezes it still works great! The only reason not to allow this to happen is that Banixx is sold in a plastic bottle and the bottle might crack if frozen.

If your bottle of Banixx freezes, simply bring the bottle back to room temperature slowly and it is good to go! In addition, if your bottle of Banixx is exposed to sunlight or heat (due to a hot summer) it still is fine and effective to use. Its pH does not alter with different temperatures and pH is critical to stop infection.
