Chances are, there are a bunch of things in your fridge that don't need to be there. In fact, there are around 20 common items -- like potatoes -- that people keep in their fridge that don't need refrigeration. Move these items to your cabinets.
I always line my vegetable crispers with paper towels or newspapers. The reason is two-fold. First, they soak up any juices that may come off of fruits and vegies, making cleaning the drawers a breeze. I just throw out the liner and put in a new one. Second, the liner absorbs any extra moisture, making my produce last longer.
Also, don't leave fruits and vegetables in their plastic grocery bags. This will make them spoil faster. Put them in an open mesh, plastic organizing basket or just leave them loose in the crisper drawer.
To keep down clutter, enforce a "one bottle" rule. For example, only one bottle of salad dressing, mustard, mayo and ketchup is allowed in the fridge at once. Your extra, unopened bottles can be stored in the pantry with no worry and you'll save a lot of space in your fridge.
While you're at it, make a no-plate rule, too. From now on, everything that goes into the fridge needs to be in proper storage containers with lids. This will reduce spills in the fridge and nix moldy plates of umm-what-is-this-mess grossness.
Remember the mantra, "A place for everything and everything in its place," from when you were a kid? The easiest way to organize your fridge is to designate a certain type of food to each shelf. When a food is put away it gets put in its place, eliminating search time and making your fridge neater. To keep track, use a dry erase marker to write the type of food on the lip of the shelf.
If bending over and wiping out your refrigerator shelves rates low on your list of fun things to do, then line your shelves with plastic place mats. When a spill happens, all you need to do is remove the mats and rinse them in the sink.
The next time you use up a 12-pack of eggs, cut off the top and put the bottom in your fridge's door shelf. The egg cubbyholes are perfect for storing squeeze bottles upside down. The bottles are organized and their contents are always ready for squirting.
If the meat you buy at the grocery store doesn't go straight into the freezer, leave it in its plastic grocery bag when you put it in the fridge. This will ensure that any leaking juices will be caught in the bag, nixing the need for cleanup.
Take some binder clips from the office and put them to work in the kitchen. My family usually accidentally tears off self-zipping bag closures on grated cheeses and such, so I use binder clips to clip bags closed, preventing spills. You can also use a binder clip to prevent stacked wine bottles and beer bottles from rolling around. Just clip it to the shelf (if you have rack-style shelving) and stick the metal ends up to block any rolling bottles.
Chances are, the items in your fridge aren't where they need to be. Some areas of your fridge are colder than others, making them better suited for certain foods. For example, the door is a good place for ketchup, hot sauce and other condiments that don't grow bacteria rapidly, but not other items.
The temperature of the the door area fluctuates a lot because of it opening and closing. That makes it a bad location for eggs, meats, milk or other items that are easily perishable, according to the USDA. Store these items on the inner shelves of the fridge to keep them fresher, longer.
Have you ever peered into a container of leftovers and wondered if you should throw it out? Wonder no more. Keep a dry erase board on your fridge and every time you put leftovers in your fridge write down the type of leftover and the date on your board. Now you'll know exactly how old a leftover is with just a glance.
