coolidor plastic smell

Ok, I'm trying to prepare a new Igloo cooler to function as my coolidor. I'm having issues removing the plastic smell. I left it open for a few days, soaked it overnight in mild bleach solution, left open again, closed with backing soda, and have just now wiped down with alcohol. not sure after the alcohol treatment (just did that) but I was still smelling plastic. Is this a issue and if so what can I do?
Thanks
