Definition & Meaning of "oven cleaner"

What is an "oven cleaner"?

An oven cleaner is a cleaning product designed to remove grease, food spills, and stains from the inside of an oven. It is typically in a spray or gel form and is applied to the oven’s surfaces, where it works to break down tough, baked-on residue. Some oven cleaners contain strong chemicals to help dissolve grease and grime, making it easier to wipe away. After application, the product may need to sit for a few minutes or longer before scrubbing.
