One thing you should do no matter what, is keep your fridge full. Every time you open the door, the cool air gets replaced by warmer air from outside. If there is more air in your fridge, your fridge is less efficient. You can always fill more space with items such as beer.
This is wrong. Too empty and it works hard because the cold is lost quickly (nothing to hold it). Too full and it’s working against the food that’s consuming the cold.
heat doesnt like state changes. That's how insulation foam works. presumably the solids and liquids you're refrigerating would be more reluctant to provide heat transfer to the warm air youre letting in, allowing the refrigerator to work less hard and just cool the new air. you may be able to pack insulation foam in there strategically , as far from the cooling mechanism as possible with little harm if your refrigerator is too empty. I did not vote on your comment.
Vegetables to the top, meat to the bottom; anything that can drip anything (liquid, blood, juice, etc...) should be placed at the bottom so to drip on the least amount of items.
Throw stuff out. Hot sauce from 2 years ago? Toss. Condiment packs from last week that you will never use? That can of hard kombucha your friend left behind?
Toss it all out. It does not good taking up space if you’re never going to use it.
Nothing to add but a tangent story. I was living in NZ 10 years ago and rented a house for NZD300 per week. The house would have been classified as a shanty in my 3rd world country. Anyways. it was winter and I was watching ice forming in real time on my glass of water as I sit in the uninsulated kitchen. It then occurred to me that the 8C in the fridge is warmer than the kitchen air temperature.
Clear containers for anything that isn't commercially labeled. My wife used to wrap leftovers (or anything, really) in aluminum foil. more than two thirds of the time I'd end up throwing it out after a couple of weeks because, since nobody knew what was in the mystery packages, nobody ate it. I bought some glass storage containers (the kind with the plastic, locking lids) so it's obvious what is contained within. A lot less waste.
Also, I've got pull-out bottom freezer with one basket and one deep "bin" and shit got lost so I 3D printed dividers and organized it.
Buy some shallow but largeish Tupperware and put anything that might leak in it. Doesn’t have to be sealed, it’s just to catch leaks. This has saved me from having to clean raw chicken juice off the fridge’s shelves many times when the butcher didn’t wrap it too well.
Keep veggies in a crisper drawer or near the top shelves, especially if you keep your fridge real cold. Less risk of freezing them that way.
Try not to cram stuff right up against the walls. This hurts your fridge’s ability to circulate cold air and can lead to freezing of some items or at least higher energy bills.
Get a black sharpie and write the date you open something on its lid. I do this mostly with dairy stuff and oat milk boxes. No more guessing how long that cream cheese, yogurt, or butter has been sitting in there.
everyone is talking about top to bottom, but nobody has mentioned that the back of the fridge is generally the coldest part, and the door is the warmest part. So put your milk at the back and not in the door.
After that idc, everything else just goes wherever it lands
Inside is the cold part. Arrange the food on the shelves then close the door. Provide an electrical source and watch as the magic of refrigeration takes hold.
Will depend on what kind of fridge you have. The bottom drawer on mine is the vegetable box. It has humidity adjustments. Next is the "fresh" box, it has a temperature adjustment for keeping meats or vegetables. Then shelves, for the rest. The higher, the more preserved is the food. The lower, the fresher.
But this is a combo fridge/freezer. The fridge on top, freezer on bottom. Freezer is much the same. There's a meat-drawer in the middle, and two everything-else-drawers.
Veggies in the door, condiments in bottom drawer, cheese drawer above that (CHEESE ONLY), good luck to everything else it’s going on a shelf. The freezer is a got damn mess tho.
I read that “condiments in a drawer, veggies in the door” can help you remember you have vegetables if you have trouble with object permanence (adhd) and no one forgets they have ketchup. I, personally, never forget I have cheese, hence the drawer full of it
Thermally conductive liquids on the outside, light, thermally insulating solids on the centre. Otherwise it's more difficult to reduce the temperature.
