Final answer:
Do not clean silver, brass, cast iron, bronze, aluminum, pewter, goldleaf, fine glassware, disposable plastics, wooden objects, or knives with hollow handles in a 3 compartment sink because the strong detergents can damage these materials.
Step-by-step explanation:
Items that should not be cleaned using the 3 compartment sink include materials that can be easily damaged by certain dishwashing detergents or sustained soaking. Items such as silver, brass, cast iron, bronze, and aluminum should avoid the 3 compartment sink due to the potential for tarnish and corrosion. Additionally, pewter, objects with goldleaf, fine glassware, disposable plastics, and anything made of wood are also at risk.
Care should be taken when cleaning knives with hollow handles, as the prolonged exposure to water can damage them. The use of 3 compartment sinks generally involves stronger detergents, such as those containing phosphates or quaternary ammonium compounds, which can be too harsh for these materials.
