Sodium Hydroxide (NaOH) is a highly caustic alkali and a strong base. It readily dissociates in water into sodium (Na⁺) and hydroxide (OH⁻) ions, giving it its high alkalinity.
Always add the Sodium Hydroxide Slowly to Cold water, not the other way around. Once the Sodium Hydroxide comes in contact with the water, it's going to cause a reaction and generate heat.
Always make sure to wear the proper PPE when handling the Sodium Hydroxide.
Recommended Ratios:
Wood Cleaning
