If you’re like most people, you probably keep deodorant in your car in a plastic or metal container. But if you’re like me, you also keep it in a Tupperware. The problem is that the plastic and metal containers can start to melt if the temperature gets too high inside the car. So how do you keep your deodorant from melting in your car? One way is to put it into a small, clear plastic or metal container. Another way is to put it into an airtight container. And finally, another way is to put it into a zip-top bag.
