Get your yellowing cotton blouse back to white again

Yellowing happens when a white garment is exposed to direct sunlight for a long time (the UV from the sunlight degrades the brightener in the fabric). To reverse this, try rewashing in detergent containing optical brighteners or brightening agents, such as Ariel, within a full load using the recommended dose and at the hottest temperature on the label. If you hang your washing on the line, keep the whites away from direct sunlight and take inside as soon as they’re dry.
