1. Do not wash with water: wooden building blocks will swell and deform after encountering water. It can’t be wiped with alcohol or wet wipes.
2. Wipe with a clean cloth: usually we can use a clean cloth to wipe the blocks, of course, not too hard, so as not to blur the picture of the blocks.
3. Drying: Wooden blocks are prone to mold when exposed to moisture, so they need to be placed on a ventilated balcony regularly, but the time does not need to be too long.
