How to maintain wooden crafts?

Update:24 Nov
Furniture or craft products made of solid wood can be painted with wood wax oil as long as it does not involve food.
Solid wood crafts are different from general furniture. As ornamental products, only wood wax oil is needed for daily maintenance to enhance the gloss and texture of the surface. Many solid wood crafts use mortise and tenon structure, so the structure needs to be disassembled when painting wood wax oil.
