Modern dishwashers use turbidity sensors—optical detectors that measure water clarity during the initial wash cycle. When you pre-rinse dishes, the sensor reads clean water and assumes a light soil load, triggering shorter cycles with lower temps.
Worse: enzyme-based detergents (powders and gels) need food starches and proteins as binding targets. No debris = enzymes flush straight out, leaving alkaline residue that can etch glassware.
Cast-iron soap myth: old lye-based soaps (sodium hydroxide) would strip seasoning. Modern surfactants only lift loose grease—they don't break the polymerized oil matrix bonded to the iron. Lodge's official docs confirm this.
Garbage disposals don't have blades. They use blunt lugs on a spinning turntable that fling food against stationary shredder teeth via centrifugal force. Eggshells can't sharpen something that isn't sharp, and their membranes clog traps.
Foil in ovens: heating elements sit under the enamel floor now. Foil reflects radiant heat back, hitting temps high enough to melt aluminum or fuse it permanently to porcelain.
