How does caustic soda affect wood?

Caustic soda, or sodium hydroxide, can significantly affect wood by breaking down its cellulose and lignin components, leading to degradation and weakening of the material. When applied to wood, it can cause discoloration, swelling, and surface damage, making the wood more susceptible to decay and pests. Additionally, prolonged exposure can result in a complete breakdown of the wood structure, rendering it unusable. Proper handling and precautions are essential when using caustic soda around wood materials.
