I’d start with washing and letting it sit in the sun a couple of days. If that doesn’t work I’d go nuclear with an ozone generator just be easy with it or it will turn the food smell into an off-gasing plastic smell, and don’t use it in an occupied space. Idealy stick it in a tote outside or something like that.
Just going to point out Catholics are the only ones who give a damn about the pope. Protestansts view it as idol worshiping, kinda the whole point of Protestantism.
