Annual Refrigerator Deep Cleaning Checklist

Most of us wipe down our fridge as needed, but a true deep clean is something homeowners should tackle just once a year. This annual refrigerator deep cleaning checklist walks you through every step I took.

I’ll be honest, aside from the refrigerator coils, I hadn’t really given our fridge a true deep clean in a long time. Sure, I’d do the occasional simple wipe-down and toss old food when I noticed it, but that’s very different from actually taking everything out, washing the shelves, and dealing with all the hidden spots that get skipped during regular cleaning.

In our house, Finn handles most of the day-to-day fridge stuff. He does the grocery shopping, keeps things organized, and is great about meal planning. But when it comes to deep cleaning tasks and appliance maintenance, that usually falls to me, and it had been sitting on my mental to-do list for way too long.

So I finally blocked off an afternoon and decided it was the perfect time to tackle a full refrigerator and freezer deep clean. Not because anything was visibly gross, but because this is one of those hardworking appliances that quietly does its job every day and deserves some real attention once a year. I’m walking you through exactly what I did so you can add this to your own annual home maintenance routine.

Why Deep Cleaning Your Refrigerator Matters

Your refrigerator is one of the hardest-working appliances in your home, running 24/7 with very little attention beyond regular cleaning. Over time, food particles, spills, and moisture build up in places you don’t see during a quick wipe-down, especially around shelves, drawers, and door seals.

A true deep clean done once a year helps prevent odors, keeps temperature settings working efficiently, and reduces the risk of potential problems like mineral deposits, clogged drip pans, or buildup that can lead to water damage. It’s also a good way to catch small issues early, before they turn into bigger, more expensive repairs. Think of it as basic appliance care that helps keep your fridge in top condition and your kitchen running smoothly.

Annual Refrigerator Deep Cleaning Checklist (Step-by-Step)

Step 1: Empty the fridge

I started by completely emptying the refrigerator. I didn’t worry about expiration dates at this point — I just needed everything out so I could see what I was working with. Even though we wipe things down regularly, I quickly realized that “seems clean” and “actually clean” are very different things.

Once the food was out, things escalated quickly…

Step 2: Remove all shelves and drawers and let them soak

I removed every shelf, drawer, and bin and put them straight into the sink with hot water and dish soap. I let everything soak while I worked on the interior, which made a huge difference later when it came time to clean them. I did a quick pass with my handheld vacuum to scoop up the big crumbs.

This is also when I discovered what we think was an olive-related incident. Finn suspects olives. I’m leaning toward some kind of marinade. Whatever it was, it had leaked underneath the drawers, solidified, and smelled, ummmm, not great. Sticky, smelly, and very motivating.

This is also when I found a yogurt tube that had fallen behind a drawer at some point and had been there for a very long time. Truly disgusting.

Step 3: Deep clean the interior (this is where it got gross)

With the fridge completely empty, I then tackled the interior, and this is where I was truly horrified. So many crumbs. So much stuck-on food. So many things I did not know were living in our refrigerator.

I used my steam cleaner for this part, and it worked incredibly well. The fridge is cold, so spills harden and are tough to remove with regular cleaning. The steam loosened everything almost immediately, and the brush attachment helped lift grime from corners and seams. I know I talk about my steam cleaner a lot, but this is exactly why — it’s something I use constantly for deep cleaning and home maintenance.

Once everything was loosened, I wiped down all the interior surfaces using a vinegar and water solution, paper towels, and a cloth. This was such a satisfying reset and a moment when I realized how overdue this cleaning was.

Step 4: Clean the door seals and rubber gasket

Next, I focused on the door seals and rubber gasket, which are very easy to overlook. Crumbs and gunk love to hide in those folds. I cleaned them with soapy water and a cloth and dried them thoroughly. It’s a small step, but it makes a noticeable difference in how well the fridge seals and how clean it feels overall.

Step 5: Wash, dry, and reinstall shelves and drawers

Once the interior was clean, I went back to the sink and cleaned all the shelves and drawers that had been soaking. Everything wiped clean easily after soaking, and I made sure each piece was completely dry before putting it back in the fridge.

Step 6: Put food back and do the real purge

Only after the fridge was clean did I start putting food back in. This is when I actually checked expiration dates and did a proper purge. Anything old, questionable, or clearly not getting eaten went straight into the trash.

I’ll be honest — I do not have a Pinterest-worthy refrigerator. I don’t use a ton of bins or gadgets, and that’s not really my goal. This wasn’t about perfect organization. It was about putting food back into a clean space in a way that made sense.

And wow, it felt lighter immediately.

Step 7: Tackle the freezer (quick but effective)

I didn’t fully defrost the freezer this time, but I did remove what I could. I wiped everything down, and got a better sense of what we actually had in there. Just seeing everything laid out was eye-opening.

We absolutely had plenty of food hiding in the freezer, which means I am no longer allowed to say, “We have nothing to eat,” ever again.

A full defrost is on my list for the future, but even this partial clean made a difference.

Step 8: Replace the baking soda and call it done

The final step was replacing the baking soda in the fridge. It’s a small thing, but it helps keep odors under control and officially marks the project as finished.

Don’t Forget the Refrigerator Coils

While you’re already in fridge-maintenance mode, this is also a great time to check your refrigerator coils. I didn’t clean ours until embarrassingly late in our homeownership journey, and when I finally did, I was completely horrified by how much dust and debris had built up.

Refrigerator coils are usually located underneath or behind the fridge, and when they’re covered in dust, pet hair, and grime, your appliance has to work much harder to keep things cold. Over time, that extra strain can lead to efficiency issues and potential problems you want to avoid.

Cleaning the coils is a separate task from the interior deep clean, but it’s absolutely part of the same annual maintenance routine. It’s one of those behind-the-scenes jobs that makes a big difference and is easy to forget if you don’t schedule it.

I’ve shared a full step-by-step tutorial on how to clean refrigerator coils, including what tools to use, where to find them on different models, and how often this should be done. If you haven’t tackled this yet, I highly recommend adding it to your checklist and working through that guide while everything is already pulled out.

Annual Refrigerator Deep Cleaning Checklist (Quick Review)

Use this as a final sweep before you call it done:

• Empty the refrigerator
• Remove all shelves, drawers, and bins
• Soak shelves and drawers in hot, soapy water
• Deep clean interior surfaces (walls, shelves, corners)
• Clean door seals and rubber gasket
• Dry all parts completely and reassemble
• Purge expired or unwanted food while restocking
• Replace baking soda in fridge
• Clean refrigerator coils (or schedule it)

Final Thoughts

Once I finished, the fridge just felt better. Cleaner, fresher, and more under control. Even though I thought it was “pretty clean” going into this, taking everything out and seeing what had been hiding under drawers and behind shelves was a very humbling experience. Equal parts horrifying and satisfying.

This isn’t something I plan to do often, but treating it as a once-a-year deep cleaning task makes it manageable and keeps one of our hardest-working appliances in good shape. It’s one of those projects that feels slightly annoying at the start and incredibly worth it by the end.

If you take anything away from this, let it be this: most home maintenance doesn’t have to be complicated, it just has to be scheduled. Block off a little time, work through a simple checklist, and then don’t think about it again for another year.
