A little humidity is good for wine: it keeps corks supple. Standing water, a stained wooden rack or a drain pan that never dries turns that humidity into mildew. The usual sources are a clogged drain leaving water on the cabinet floor, a pan beside the compressor full of old water and wine residue, a bottle that seeped past its cork and soaked a rack, and a gasket with mildew in its folds. Some wine coolers draw fresh air through a charcoal filter in the back wall, which the makers ask owners to change on a schedule; an old filter lets odors build up. A musty smell rarely taints the wine in a sealed bottle, but it spots labels, which matters for bottles you may one day sell or give. The 6 causes, cheapest first Answer these first 01 Is there water under the bottom rack or in the drain channel on the back wall? 02 Is any rack stained or sticky from a bottle that leaked? 03 Does your model have a charcoal filter, and when was it last changed? 04 Are there gray or black spots on labels, corks or the gasket? 05 Was the cooler off or unplugged with its door shut for a while? ## Check these before you book. Wine cooler smells musty: 5 checks, and none of them costs anything. 01 Move the bottles to a cool dark shelf, wipe the cabinet and the racks with warm water and a little baking soda, and dry everything. 02 Clear the drain hole at the foot of the back wall and check for standing water. 03 Look into the folds of the gasket for mildew and clean them with a soft brush. ### Also worth checking - Change the charcoal filter if your model has one and it is more than a year old. - Tell us whether the smell returns within a week, and the model number. ### How soon does it need a visit? A musty smell is not urgent. Book a visit if it comes back within days of a cleaning, which points to water standing where you cannot reach. ## The causes, cheapest first. 6 things wine cooler smells musty turns out to be, from leaked bottle soaking a rack to gasket with mildew in its folds.

Rarely. A sound cork keeps the smell out of the wine. The labels, capsules and outer ends of the corks are what suffer, and a spotted label lowers the value of a bottle you plan to sell. ### What is safe for cleaning the inside of the cabinet? Warm water with a little baking soda or mild dish soap. Avoid strong-smelling cleaners and bleach; their scent lingers in a closed cabinet and near the corks. ### How often does the charcoal filter need changing? Makers that fit one generally suggest about once a year. The manual shows the part and how it twists or slides out of the back wall. ### Why does the smell come back after a thorough cleaning? Water is standing somewhere out of sight: the pan under the cabinet, a clogged channel or inside the gasket. Finding it is a short visit. --- **[Read on the site: Wine Cooler Smells Musty: Causes and Fixes](https://winecoolerrepair.center/problems/wine-cooler-smells-musty/)** **[Book a visit with WineCoolerRepair.center](https://winecoolerrepair.center/schedule/)**
