Why do solid wood cabinets become moldy and what causes them

Ask about the back panel of the cabinet.

Is this moldy?

Reply. The fungi that cause wood mildew include Trichoderma, Penicillium, Aspergillus, Mucro, etc. The most important of Trichoderma fungi is Trichoderma viridum, and the surface of wood infected by this fungus is green.

There are many types of fungi in Penicillium and Aspergillus, such as Aspergillus niger, and when the wood is infected with this mold, the surface is black spots, sometimes connected into patches.

Yellow ones like you need to clean up the remaining garbage inside.

For cabinets that have become moldy, you can wipe off the mold with a dry cloth or paper towel first, and then brush the varnish again. If you can't wipe off the mold with a dry cloth or dry paper towel, you can use a wet paper towel or damp cloth to wipe it vigorously a few times.

For indoor areas prone to humid weather, dehumidification can be performed.

However, due to the fact that the log cabinet itself has the function of automatically adjusting the humidity, it is not recommended to dehumidify frequently, and it is usually enough to dehumidify once a month. You can put some orange peels in the whole cupboard, and put a box of quicklime in an inconspicuous place in the kitchen, which can be damp or disinfected. The room should also be ventilated frequently, and the afternoon is the best time to ventilate.

On rainy days, doors and windows facing south or southeast should be closed to reduce the inflow of moisture into the room. At noon, the air humidity outside is at its highest, and it is not advisable to open the windows. In the afternoon or evening, when the climate is relatively dry, open the window to regulate the indoor air.
