If you don't want to risk staining any light clothes, keep them apart.
Separate laundry by fabric or texture: Heavy fabrics like denim jeans and towels require a different washing-machine cycle than delicate items (like bras and lingerie) or medium-weight ones like sheets.

Read the care label on clothing before washing. Some clothing can only be dry cleaned while other clothing, like that made of wool, needs to be hand-washed with a special soap and dried by placing
