Found a treasure in the back of the bathroom shelf: A 250 ml bottle of disinfecting spray and a 100 ml bottle of hand disinfectant. Now, they're both beyond their "use by" date, but the main and active ingredient is propanol, so I doubt that they've gone bad (their effectiveness against some promised microorganisms may have suffered). The spray has fragrances added to it, though, that trigger my asthma. Seems the manufacturer believes people hate the smell of propanol. I don't. I worked in a lab. I like the smell of propanol in the morning. Smells like ... sterile surfaces.
