Removing Lettering from Hoodie

Hey there! I'm looking for advice on removing lettering from a hoodie. Apologies, this isn't exactly sewing! My mom thrifts me clothing as gifts often (I'm very lucky, she gets really good stuff 50% of the time!) and she didn't notice that this hoodie was a Jersey Shore hoodie. I haven't seen the show, but reality tv is not really my thing and from what I've heard it doesn't really go with my personality. I like the hoodie though! I believe it's vinyl lettering, but I'm not very good with material types so correct me if I'm wrong. I've tried ironing and rubbing alcohol but it isn't peeling like Google says it should, so I'm confused. Does anyone know if it's possible to easily remove this kind of lettering, and if so, how? Thank you much! Newbie here, so sorry if this is not a good post for this group!
