A magnetic fridge door feels like free storage, and it mostly is — but not everything belongs on steel. Put the wrong thing there and it falls, rusts, or just looks like a yard sale. After organizing a few of these, the list of what's safe and what's not gets short and useful. Here's the practical version so you don't learn it the messy way.
Put these on the door
Light, daily-reach things: condiment jars in the magnetic basket, spices in the door rack, the odds and ends in the side storage box, and paper towel or foil in the 3-in-1 dispenser. None of it is heavy, all of it you grab daily, and all of it behaves because the magnets hold through the swing.
Skip these
Anything wet or greasy — it creeps under the magnet and the steel rusts. Anything heavy like a full olive-oil jug or a cast pan — it'll test the magnet past its rating and drop. Anything you'd be heartbroken to lose if it fell. And skip sticking paper or photos with tape over the magnets; the door's for storage, not a bulletin board.
The one rule that covers it
If it's light, dry, and daily, the door is its home. If it's heavy, wet, or precious, a cabinet is safer. That's the whole filter. For the gap behind the fridge too, see using the gap between fridge and wall.
Stock the door right: shop the magnetic basket and the side box.
