Has anybody tried sterilizing their eliquid bottles in the microwave for 2 to 3 minutes? Does it work? Wondering if the bottles are microwave proof. About the only thing I use my microwave for is sterilizing my kitchen sponges and auto-defrosting food I've forgotten to take out of the freezer for my pups. I've read on the news and science sites that microwaving sponges will kill all bacteria including e coli and salmonella. Please and thank you.
