Now, for the fussy items—your silk blouse, your wool sweater, that cashmere scarf your aunt gave you. These are not for the hot water treatment.
Hand-washing them with tap water is a no-go unless you boil the water first and let it cool. It’s like asking a vampire to take a bath in holy water—just messy.
Better idea: wait until the advisory is lifted. Or use distilled water from a store. Your cashmere will forgive you, I promise.
