I tried to use a coal before to remove the bad smell on our fridge. And I believe it worked well. Anyway, thanks for the good advice Nestor!Try putting coal in a cup inside the refrigerator. This will suck the foul smell inside your ref. I also use baking soda once in a while but this thing seems to lose its absorbing power by one day only. Coal is more effective. If you really want to use baking soda, I bet its meant to be use for scrubbing the ref when you try to clean it.
