When i was an intern in a store, i hardly resisted to organize the shelves while my own shopping.
Except for food, I tend to date and initial anything I open. Pedialyte–initial and dated. Medicine–initial and dated. It’s definitely something that has to be done at my job, but is also kinda helpful at home. Oh, that isopropyl alcohol has been open for 2 years, better get a new one.
Isopropanol expires? I had no idea! lol. I guess moisture getting into the solution could impact the concentration?
