How to get rid of the smell on my coffee cup?
Some weeks ago I was shopping at Walmart and was thrilled to spot this amazing gorgeous DC Harley Quinn cup among other popular DC character cups. Naturally I bought it but after drinking from it once time I noticed there is a kind of odor that smells to me like something pickled. I figured the paint probably didn't cure long enough so I've let it sit in the cupboard and even after multiple washes and a long time setting in the cupboard there is still some kind of smell on it. What is it and how do I get rid of that smell?
