coolidor plastic smell

When I set up my coolidor I washed it first in a bleach solution, rinsed very well and then left it outside, open, to sun dry all day. This got rid of all but the tiniest plastic odor. After bringing it in that night I washed with a clean washcloth and a baking soda solution followed by a rinse. Left it open to dry overnight and had no plastic odor the next day. I think being open in the sun had almost as much effect as the bleach.
