Grangers Performance Wash

Grangers Performance Wash is a wash-in product designed to gently clean all technical garments including natural and synthetic down-filled items without damaging or inhibiting their insulating or hydrophobic properties.

Picking the right detergent is incredibly important. Regular household laundry detergents can leave various chemical residues behind after washing, reducing a garment’s ability to insulate or repel water. Grangers,  on the other hand, has been formulated to thoroughly clean without damaging the delicate material within.

    • Removes dirt and neutralizes odor without reducing loft or impairing performance.

      Specially formulated to clean all down-filled articles

      Can be used to prepare a garment for future water-proofing treatments.

      Best used in conjunction with a tumble dryer – down items should always be tumble dried when appropriate.

      A bluesign® system approved product.
