Chore Boy is a brand name for a coarse scouring pad made of steel or copper wool. It is designed for cleaning very dirty surfaces, especially washing dishes. During the first half of the 20th century, the product was marketed under the name Chore Girl.
Chore Boy is also the brand name of hi-tech labor-saving dairy milking systems and an associated line of fluid-handling equipment that was produced between the 1960s and 1980s.
