I got the medium RTT heart tag with enamel last week on Tuesday... The whole silver side is already tarnished VERY badly and I haven't used any hair product, perfume that it can come in contact with 
Do I just need to use silver polish every time I wear it enamel side out? I literally wore it one day with the silver side to my skin, and a few days it was silver side down but over a t-shirt. I took a bit of toothpaste to it and it took off some of the tarnish but the majority is still there. I haven't had this problem with my initial note disk charm and I've had that for almost a month, skin contact and not.
A gal at work told me to take it back and have them exchange it. Idk!
I've also had my filigree heart pendant for two months and that hasn't tarnished either.
