Rex washing powder is a laundry detergent used for washing clothes.

Like other laundry detergents, Rex washing powder is designed to remove dirt, stains, and odors from clothing during the washing process. It may come in various formulations, including powder or liquid, and may be suitable for both hand washing and machine washing.

Rex washing powder likely contains a combination of surfactants, enzymes, and other cleaning agents to effectively lift dirt and stains from fabrics. It may also contain brighteners to help maintain the vibrancy of colored clothes and fragrances to leave clothes smelling fresh after washing.
