I've had no problem re-using them. I let them soak in the hottest possible water with lots of soap but I also heavily spritz them with anti-bacterial sanitizer. That seems to kill off anything that's left in the mechanism. I let them sit in a bowl until the water cools down. Then I refill it again with the soap, sanitizer and water. I fill the little vials with the mixture of hot water, soap and sanitizer and start spraying them until they are empty. But, I'll fill them repeatedly (and depending on the scent that was originally in them) this can take up to 20 times of spraying them till they're empty to get rid of the original scent. I'm big on re-cycling and see no need to toss them. I've managed to re-use all of mine and never had to throw one away yet. This way, I've managed to save on the cost of buying new ones, I have ones to spare for share and I'm saving the environment. Do a few at a time to save energy, too.
