Down Wash is a powerful, yet gentle, cleaner specifically formulated to clean all your down and synthetic down-filled articles without damaging or inhibiting insulation or hydrophobic properties. It’s important to take care of your down so it keeps you warm and dry. Normal detergents shouldn’t be used on down articles as they can hinder the performance by leaving various chemical residues behind and reducing the garment’s ability to insulate or repel water. Luckily, Grangers Down Wash is exactly that, a wash that has been formulated to thoroughly clean down items without damaging the delicate material within.
