So I have one of these bottles for protein shakes. I made one before school on Thursday before class since I was going to the gym after. I drank most of it, but there was a little bit left in the bottom. I mix mine with milk and that little bit sat in the bottom until yesterday when i opened my back pack up.
I cleaned it out and put it through a hot cycle in the dish washer. The smell is like ingrained in the bottle and I don't want to toss it ~_~
How the hell can I get the smell out? Microwave it with some scented soap or something in it? I don't mind if it has a smell to it, but NOT sour milk.
