Because wood swells and deforms when exposed to water, wooden toys cannot be washed with water. Usually we can use clean damp yarn
Use a cloth or handkerchief to gently wipe the surface of the building block, or use some natural cleaning liquid, soapy water, and then wipe with a cloth.
In the humid climate area, in order to prevent the toys from getting wet, you can put a desiccant during storage, and try to avoid backlogs in the storage of filled toys to avoid
Deformation damage.
Because wooden toys are prone to black mold when exposed to moisture, they should be placed on a ventilated balcony to dry regularly--small meetings, and they must be flipped when drying-down,
Allow different sides to dry fully. Remember not to expose to the balcony to prevent cracks on the painted surface and wood.

Wooden toys are the continuation of the life of trees. If they are carefully cared for, they can accompany the whole childhood of children!
