I've had some of my perfume forever. I rarely wear the old ones, partially because I'm just sick of looking at their crusty, tired, old bottles. To my surprise, I found an incredible vintage perfume bottle at the thrift store this week! Amazing! I soaked the vintage bottle in hot water and Bronner's soap for about a half an hour, just to make sure the old perfume smell wouldn't linger. After that, I simply poured the contents of my long had perfume into the new bottle and just like that, good as new and even better!
