How do I clean mold out of a wine fridge?

Unplug the unit first, then wipe every moldy surface with a 1:1 solution of white vinegar and water — vinegar kills most mold spores on contact and is safe on every wine fridge interior, unlike bleach. Rinse with a clean damp cloth, then dry the cabinet completely with a towel before leaving the door open to air out for a few hours. If mold keeps returning after repeat cleanings, the real cause is usually a wet door seal or a clogged interior drain, not a cleaning-product problem — dry those two spots specifically.

How often should I clean a wine fridge?

Wipe the interior down every 1-3 months, and do a full clean — shelves out, door seal wiped, drip tray checked — twice a year. Clean the condenser coils on the same 3-6 month schedule recommended for repair prevention (see our wine cooler repair guide); dirty coils are a cooling problem, not a hygiene one, but they're easy to knock out during the same maintenance pass.

Why does my wine fridge still smell musty after cleaning?

Three causes account for most repeat musty smells: a door seal that stayed damp after cleaning instead of being fully dried, a saturated activated-carbon odor filter that needs replacing (most models with one need a swap every 6-12 months, and a spent filter can start adding odor instead of removing it), or a clogged interior drain letting condensation pool somewhere you can't easily see. Re-cleaning the same shelves again won't fix any of those three.

Can I use vinegar to clean a wine fridge?

Yes — white vinegar diluted 1:1 with water is the universal-safe interior cleaner for every wine fridge brand, since it kills mold spores without the residue risk bleach carries in a small sealed space. For odor specifically, leaving an open, shallow bowl of undiluted white vinegar inside the unit overnight neutralizes smells the same way a box of baking soda does, per NewAir's own owner's-manual guidance.

How to Clean a Wine Fridge (2026): Mold, Odor, and What Not to Use

Q: Is it safe to use bleach in a wine fridge?

It depends on the brand, so check your owner's manual before reaching for it. EdgeStar's own support documentation recommends a 1-part-bleach-to-10-parts-water solution for interior wipe-downs, but several other wine fridge manufacturers explicitly forbid bleach and ammonia inside the cabinet because residue can linger in a small sealed space and taint bottles stored afterward. Vinegar or mild dish soap and water work on every unit regardless of brand, which is why they're the safer default when you're not sure what your manufacturer allows.

Quick Answer: Unplug the unit, then wipe the interior with a 1:1 white-vinegar-and-water solution or mild dish soap and water — both are safe on every wine fridge brand. Skip bleach unless your specific manufacturer’s manual approves it: EdgeStar’s own support docs recommend a 1:10 bleach-to-water ratio, but several other brands forbid bleach and ammonia inside the cabinet entirely because residue can taint bottles in that small sealed space. Kill lingering odors with an open box of baking soda or a bowl of vinegar left overnight, dry everything completely before closing the door, and if a smell keeps coming back, check the door seal and the carbon odor filter (if your model has one) before re-cleaning the shelves again.

Every wine fridge cleaning question eventually comes down to two things owners get wrong: using a cleaner that’s fine for a kitchen fridge but risky in this smaller sealed cabinet, and re-cleaning the same shelves over and over without finding what’s actually re-wetting the interior. Here’s the manufacturer-approved method, the mold-specific fix, and the parts most cleaning guides skip entirely.

Wine fridge cleaning by the numbers

1:10 is EdgeStar’s own recommended bleach-to-water ratio for interior wipe-downs, per the brand’s support documentation — but EdgeStar stresses this is brand-specific, and several other manufacturers forbid bleach in the cabinet entirely, which is why checking your own manual first matters more than following a single ratio blindly.
2 tablespoons per quart is NewAir’s recommended baking-soda-to-warm-water ratio for washing interior surfaces on its wine coolers, per the brand’s owner’s-manual guidance.
50-70% relative humidity is the same range our wine fridge temperature guide recommends for keeping corks from drying out — and it’s also the range where mold grows fastest if the interior isn’t cleaned and dried on a schedule. The humidity that protects your wine is the same humidity that breeds mold in a neglected cabinet.
6-12 months is how often an activated-carbon odor filter needs replacing on the models that include one — a step that’s mentioned as a feature across several product pages on this site but rarely tied to a replacement schedule, and a spent filter can start contributing odor instead of absorbing it.

Step 1: Empty it out and unplug it

Remove every bottle and take the shelves or racks out if your model allows it — most slide out the same way a refrigerator shelf does. Unplug the unit at the wall rather than just powering it off; this matters if you’re using any liquid cleaner near the compressor or control panel, and it also resets the compressor cycle cleanly when you plug it back in.

Step 2: Wipe the interior — and know what your manual actually allows

For the interior walls, shelves, and door gasket, two methods work on literally every wine fridge brand:

1:1 white vinegar and water, wiped on with a soft cloth or sponge. Vinegar kills most mold spores on contact and leaves no residue that could transfer to a bottle later.
Mild dish soap and warm water, or NewAir’s own ratio of 2 tablespoons baking soda per quart of warm water for stubborn stains, wiped on with a soft cloth.

Bleach is the one product where brands genuinely disagree. EdgeStar’s own support documentation recommends a 1-part-bleach-to-10-parts-water solution for interior cleaning. Other manufacturers explicitly forbid bleach and ammonia inside the cabinet, because the unit is a small, mostly sealed space — leftover residue has nowhere to fully air out the way it would in an open kitchen, and it can end up tainting the next bottles stored there. Check your owner’s manual before you use bleach on any wine fridge; if you can’t find it or the model is old enough that the manual’s gone, stick with vinegar or soap-and-water instead, since neither has a downside on any brand.

Rinse with a clean, water-only damp cloth after either method, then dry every surface completely with a towel — a damp interior is exactly what lets mold restart within days.

Step 3: Mold that keeps coming back isn’t a cleaning-product problem

If you’ve cleaned the same mold spot more than once and it returns, the vinegar or bleach isn’t the issue — something is keeping that spot wet between cleanings. The three real causes, in order of how often they show up:

A door seal that never fully dried. Wiping the gasket and closing the door immediately traps residual moisture right where mold started in the first place. Dry the seal with a towel and leave the door cracked open for a few hours before closing it fully.
A clogged interior drain or drip channel. Some units route condensation through a small internal drain; if it’s blocked, water pools somewhere behind a shelf or panel you’re not wiping. This is the same drainage issue that shows up as a leak in our wine cooler repair guide — worth ruling out if mold is concentrated in one spot rather than spread evenly.
Humidity sitting at the high end of the 50-70% range without airflow. That range is correct for cork preservation, but a fully packed, rarely opened unit gets less air circulation than a lightly loaded one — crack the door briefly during your cleaning pass instead of sealing it the moment you’re done.

Step 4: Kill odors without harsh chemicals

Two manufacturer-recommended methods handle lingering smells without any risk to stored wine:

Baking soda, either in an open dish left inside the unit, or per NewAir’s guidance, stuffed loosely as newspaper-wrapped packets overnight, then run the unit a full day afterward to finish airing out.
White vinegar, in a shallow uncovered bowl left inside overnight — it neutralizes odor the same way baking soda does, without leaving a residue on shelves.

If odor returns within a week or two of a full cleaning and neither method helps, check whether your model has a carbon or activated-charcoal filter — several units on this site mention one as a feature, and like any carbon filter, it saturates and needs replacing roughly every 6-12 months. A spent filter stops absorbing odor and can start releasing a stale smell of its own, which is easy to mistake for a cleaning failure when it’s actually a filter-replacement issue.

Step 5: Exterior and door seal

Clean the outside cabinet with mild detergent and warm water, avoiding abrasive pads or scouring powders on stainless finishes — they scratch the brushed grain permanently. Wipe the door seal/gasket specifically during every cleaning pass, not just when you’re chasing mold: dirt and grime on the gasket compromise the seal the same way physical wear does, which is the failure mode covered in more depth in our wine cooler repair guide.

How often to clean

Interior wipe-down: every 1-3 months, more often if you store opened or leaking bottles.
Full clean (shelves out, gasket, drip tray): twice a year.
Condenser coils: every 3-6 months — a cooling-performance task, not a hygiene one, but easy to do in the same session.
Carbon odor filter (if equipped): every 6-12 months.

The bottom line

Vinegar diluted 1:1 with water, or mild soap and water, cleans every wine fridge brand safely — bleach only if your specific manufacturer’s manual says so, since several explicitly don’t allow it in this smaller sealed space. Dry the interior and the door seal completely before closing the unit back up; that single step prevents more repeat mold than any cleaning product does. And if odor or mold keeps coming back after real cleaning, look at the door seal, the drain, and the carbon filter’s age before assuming you’re just not scrubbing hard enough.
