These shallow, typically round or square receptacles are designed to be placed beneath stovetop burners or under other appliances that may leak or spill. Available at a large home improvement retailer, they serve as a protective barrier, preventing liquids from reaching and damaging the appliance surface or the floor beneath. For example, a pan placed under an electric stovetop coil catches food particles and spills, simplifying cleanup and preventing baked-on messes.
The use of these items offers several key advantages. They significantly reduce the time and effort required to clean stovetops and other appliance surfaces. By containing spills and drips, they protect appliance finishes from staining, corrosion, and other forms of damage, potentially extending the life of the appliance. Historically, similar devices have been used in various industries to contain leaks and prevent environmental contamination, highlighting the principle of preventative maintenance.
