Edwal Orthazite shelf life

[C A Sugg]

I've had a sealed bottle of liquid Orthazite for 2-3 years. Should this have deteriorated significantly? I'm planning to try it out on a batch of Mitsubishi Gekko graded fiber and was wondering if I should replace the chemical first before evaluating the fog suppression effects.
Thanks,
Charles

No. Its ingredients should be still good.

I've had a partially opened bottle for ten years, and its contents are still fine.
