Ariel distinguishes sweat marks that may become grey over time from deodorant or antiperspirant deposits that can look yellow, green, or brown and feel crusty. Its treatment starts with brushing away surface residue and a cold rinse, followed by a suitable detergent wash within the garment's care instructions.

Prevention focuses on timing as well as cleaning. Wash clothing soon after wear instead of leaving deposits in a hamper for days. Apply only a thin layer of the underarm product and let creamy or liquid formulas dry before dressing, reducing the amount transferred onto the fabric.
