Generally speaking, most poppers will last between 1-3 months. Exposure to light, heat and oxygen will all shorten your popper’s life-span, so it’s important that these are limited as much as possible. You may have noticed that most popper bottles come in a dark orangey-brown glass. This is a deliberate choice to reduce damage due to light exposure. While the bottle will go some way to limit light-degradation, it’s still recommended to store your bottles in a dark place. When it comes to heat, the importance of limiting this will vary depending on your local climate. If you live somewhere hot, or it’s summertime, consider storing your poppers in the fridge to avoid evaporation. In cooler climates it is possible to successfully store your poppers at room temperature, but we would still recommend using the fridge. Cooler is always better.  Oxygen is a simple, but important, one. Poppers will start to evaporate quite fast when exposed to oxygen. Replace the cap on your bottle as soon as you’re done using them, and don’t leave the bottle open on the side in-between uses. Ensuring the lid is back on tight will also limit exposure to oxygen.  Unfortunately it’s not possible to completely stop the degradation process of poppers, this would essentially require the sub-zero temperatures of space - but using the above you can significantly slow it down!
