Hydrogen sulfide dissolved in water corrodes metals such as iron, steel, copper and brass. The corrosion of iron and steel from sulfur forms ferrous sulfide or “black water.” Hydrogen sulfide in water can blacken silverware and discolor copper and brass utensils.
Sulfur water makes cleaning clothes very difficult. Using chlorine bleach in sulfur water reduces the cleaning power of detergent. Hydrogen sulfide in water also corrodes exposed metal parts in washing machines.
Iron and manganese, often present with hydrogen sulfide, turn the water black and greasy-feeling. If untreated, the water stains laundry, washing machines, sinks and kitchenware. When used in the laundry, chlorine bleach reacts with iron and manganese forming dark rusty or brownish stains on clothes.
