I transfered them to different tubberwears after I first noticed the smell, then it came back.. I moved it again and it's back (all over the period of about 3 days)

I just threw em all in Rubbing Alchohol for a second and then into a clean paper towel and new tubberwear.. I might've messed them up with the rubbing alchohol I'm not sure but if the smell dosen't come back and they pop I'm gonna assume it's okay.
