How to remove that musty smell from the kitchen cabinet?

The musty smell in the cabinet is really annoying, especially in the kitchen where you want everything to stay fresh. First, you really need to dry out the space. Take everything out of there, wipe down the shelves and sides with a completely dry cloth, and leave the cabinet open for a while so it can air out properly. If the humidity is really bad, you can even use a hair dryer - just run it through there quickly to help evaporate any water that's lingering.

Once everything's dry, put in some stuff that absorbs moisture. Silica gel works great for this - those little packets you get with new electronics are perfect, just save them instead of throwing them away. Another really common option is to use baking soda in an open container inside the cabinet, and swap it out every month or two. Activated charcoal also soaks up moisture really well, and as a bonus it absorbs bad smells too. Put one or two containers in different corners of the cabinet.

Now, the real important thing is figuring out why it's humid in the first place. If your kitchen is generally humid (it probably is, because kitchens always have this problem), you need to improve the ventilation. Open the windows after cooking, use your range hood properly, and if you can, put a fan in there to circulate the air better. If the cabinet is near the sink or somewhere that gets splashed with water, then you need to dry everything thoroughly whenever you wash something nearby. Some people also put mothballs in there, but then your cabinet's gonna smell like that really distinctive mothball smell, so it just depends if you like it or not.

I had exactly this problem here at home and ended up figuring out it was a combination of things: first I'd dry it really well with a cloth, then I'd leave the cabinet open for a few hours to get some actual air circulation going, and then I'd put a little container with used coffee grounds (that powder left in the filter) inside.

It works well because the coffee absorbs the smell and moisture at the same time, and you don't have to keep replacing it every week like you do with silica gel. If the problem keeps happening, it's worth checking if there's a leak or water seeping in behind the cabinet, because then no trick is gonna work until you dry out the source.

Silica gel or activated charcoal work pretty fast, but then you gotta replace them like every month.

In my case, what actually worked was leaving an open box of baking soda inside the closet - it's super cheap and lasts like 3-4 months before you need to swap it out. And a little bit of ventilation makes a difference too, like leaving the door open for a few days when the weather's dry, or just putting a portable dehumidifier nearby for a while.

Humidity in the kitchen cabinet gets much worse if there's no air circulation, so it's really worth leaving the door open whenever you can - I even do it while I'm cooking. Besides drying things well with a cloth, what worked for me was putting a shallow bowl with coarse salt inside, which absorbs the humidity without needing constant maintenance like other methods. You change it maybe every two or three months depending on how humid the space is, and it's much cheaper than constantly buying silica gel.

People are just focusing on absorbing the moisture, but nobody mentions checking if there's a leak or water infiltration behind the cabinet - sometimes the problem runs deeper and an absorbent won't fix anything. If it's just moisture, take everything out, dry it well with a cloth and run a fan pointed inside for a few days - that makes a huge difference.
