Why does my new iPhone case smell?

I just got a new iPhone case from Claires and it smells musty
It's one of them stretchy ones.
How can I get rid of the smell?

Wash it with a little shampoo or dish soap and let dry. And i don't know y it smells lol

You can spray perfume, and dry it on your case of just plain wash it. Make sure to dry it before you apply it to your Phone. Foot spray works too! Hope this helped!

Wash it or spray it with perfume

Return it if it bothers you that much. It's going to smell even worse when you're talking to someone on the phone and it's super close to your face. So you may as well go and get your money back.

Your case is one of the stretchy ones, so i can see your case is made of rubber or silicon.normally this kind of case has some smells, because of the materials, but if you can wash it and put it in some place with wind for one or two days, that smell will be less or gone. Hope you can get rid of the smell soon
