If your fridge has a really bad smell, what you can do is to wrap a piece of charcoal and put in the fridge. After a day, the smell will be absorbed into the charcoal. Try it if you do not believe me.
In the same way, you can also put crushed newspaper into your smelly shoes. Next day, it will have no smell at all. You do not even need to spray those un-natural perfumes into your shoes. Charcoal can absorb any smell that you want to get rid of. It is natural and good!
