Sodium hydroxide—commonly known as lye or caustic soda—is available at various local retailers and specialized suppliers for use in soap making, biodiesel production, and plumbing maintenance. Common Local Sources for Sodium Hydroxide
Large general retailers often carry pure lye in their plumbing or cleaning aisles.
When mixing, always add the lye to water—never water to lye—to prevent a violent exothermic reaction or "volcano" effect.
Frequently used on industrial or cleaning-grade labels.
