I don't think I just got used to it though maybe that helps. But I think usually a smell comes from the place they were in before having something in the air that stuck to the phones, like something they cooked with or product they used or something. So when it's in a new environment without those things in the air, and doesn't have contact with new stuff, I think whatever is on the phones slowly goes away. I bet fresh air and sun would be the best. But drivers don't like sunlight.
I guess it depends on what the smell is.
