Lye

Lye is a highly alkaline substance, typically sodium hydroxide (NaOH) or potassium hydroxide (KOH), in a concentrated solution. Historically, it was produced by leaching wood ashes, hence its association with cleaning. lye is a corrosive agent, meaning it can burn or damage organic tissues. It's used in soapmaking, as a drain cleaner to dissolve grease and hair, in food processing (like making pretzels), and in industrial processes. Proper handling of lye requires protective gear due to its caustic nature. Never mix lye with aluminum.
