ᐅ Kallax stored in the basement after moving out – has a musty smell

MofarHello everyone,
A few months ago, I stored my Kallax shelf in the basement after moving out of my apartment. Since placing it there, I’ve missed the natural scent of the wood – by now, the shelf smells quite musty and doesn’t seem very fresh anymore.
The basement is heated but also relatively humid and not ventilated very often. I placed the shelf directly on the floor, without any cover or special measures.
My question is whether the musty smell typically results from the damp basement environment, and if there are any proven methods to remove or at least improve the odor with minimal residue.
Are there also options to treat the shelf afterwards, or would it be better to remove it completely from the basement?
Any ideas or experiences would be very helpful, thanks in advance!

First, to explain: The musty smell problem with your Kallax shelf in the basement is very likely related to high humidity and poor air circulation. Kallax shelves are made of medium-density fiberboard (MDF) with a melamine coating, which absorbs moisture and can therefore retain odors.
You should first check the humidity level in your basement – ideally, it should be between 50% and 60%; significantly higher levels quickly cause musty smells.
That is the core of the problem.
To neutralize the odor, I recommend the following steps:
1. Wipe the shelf thoroughly with a slightly damp (not wet) microfiber cloth – if needed, use vinegar water (1 part vinegar, 3 parts water), as vinegar inhibits mold and bacteria and binds odors.
2. Afterward, be sure to let it dry well, ideally placing it in a dry, well-ventilated area.
3. Ventilate the basement carefully or use a dehumidifier.
4. Activated charcoal bags or baking soda inside the shelf may also help absorb odors.
If this does not help, a surface treatment with wood oil or a special wood refresher oil could be useful, as these provide hydrophobic properties. However, test very carefully on MDF first, since the melamine coating is non-porous and such treatments often have limited effect.
What does direct contact with the floor mean? Is the shelf standing on a pallet or directly on concrete?
Direct floor contact increases moisture absorption. So if possible, use spacers (e.g., wooden slats) as a base.
How long has the shelf been in the basement, and did the smell occur immediately after placing it there or only after some time?
Regards,

The musty odor issue with your Kallax in the basement is most likely related to high humidity and poor air circulationI would like to agree with this and add a few points:
Although the MDF panels that Kallax is often made of are melamine-coated, the cut edges are still quite vulnerable to moisture. Moisture can accumulate there and lead to microbial growth (mold, fungi), which causes a strong musty smell.
Additionally, depending on the insulation, the basement wall itself can allow moisture to pass through, which keeps the indoor climate problematic over time.
My recommendations would be:
- Treat the shelf with a dehumidifier, ideally keeping it running for a medium term to reduce humidity below 60%.
- Seal the cut edges with a special wood protective varnish, if possible.
- Do not place the shelf directly on cold flooring, but be cautious when using wooden strips – they can also absorb moisture if improperly fixed or in contact with the floor.

should I remove it completely from the basement?If you have the option: yes, especially if the basement is persistently damp and well ventilation is not possible, this is the most sustainable solution. PVC flooring or other underlays can also trap moisture and increase odor.
If relocation or storage in the basement is unavoidable, I recommend at least placing the shelf temporarily on a pallet or dry surface and ventilating regularly, possibly using a room dehumidifier.
Hello Mofar,
I understand that a musty smell can be very unpleasant, especially with furniture that should normally have a typical wood scent.
I have stored some Kallax furniture in my basement under similar conditions, and a few things have helped quite well:
- Ventilate the basement as regularly as possible, even when it’s cold outside. Basements tend to become even more humid in winter, especially when heating is used.
- Place activated charcoal or odor-absorbing bags on the shelves (there are products specifically designed for furniture or rooms). These help bind moisture molecules.
- Some vibrating climate dehumidifiers can be placed in the basement, and they are often quite affordable.
- Avoid direct contact with the floor. It’s best to use plastic feet or wooden strips under the shelving so that air can circulate from below.
- After cleaning, leave the furniture in a well-ventilated room (garage, living area) for a while to air it out.
Removing the smell entirely is difficult if it has been absorbed by the wood for a long time – but airing out, treating with vinegar water, and using absorbers (like activated charcoal) can usually reduce the odor significantly.
So: You’ll need patience and a combination of methods.

warrenka5715 Dec 2022 16:48I always find it upsetting when furniture that has become dear to you suffers because it cannot be stored properly. Your concern about the musty smell is completely understandable.
It might also be worth considering temporarily improving the basement’s dryness, perhaps with a small battery-operated dehumidifier or regular airing out by opening windows briefly.
If the shelf has a lot of sentimental value to you, you could also try gentle cleaning agents like baking soda solutions (baking soda dissolved in water), which can help neutralize odors.
But be sure to check whether the smell might already be coming from mold – some musty odors are associated with mold and can be a health concern. If that’s the case, I would reconsider the storage environment.
Maybe you can simply try placing the shelf in a drier location and see if the smell improves.
