hey guys three minutes ago I just talked to the collection manager at the geological-paleontological collection at the University of Leipzig, and he told me that you can use Rewoquat after years of storage … no problem. It is just a combination of some tensides and there is no limited shelf life. He also will give me the address to purchase it for our needs.
All the best from Germany
