Mineβs not smelly. Like others have said, I use glass containers for leftovers etc, and I also wash and store like lettuce and veggies in ziplock plastic bags. I probably deep clean mine a couple times per yearβ¦ definitely spot clean if there are spills etc.
If you have any odors you could try putting a box of baking soda in your fridge to absorb them. They actually sell fridge boxes of them with side panels that are mesh and easy to use.
