I have a North Face Gore tex jacket that is about 7 years old and recently started absorbing water I tryed washing amd heating but it became clear I needed to recoat. I followed the instructions as closely as I could to make it work with my washing machine. First, I washed and dryed the jacked per manufacturers instructions. The I put the liquid in the fabric softener tray, ran a delicate load with the lowest soil setting, warm water, and no spin. When the cycle finish I threw the soaking wet jacked straight into the dryer on medium heat for 1 hour. After the dryer finished I tested it in the sink and it beads water like they day I got it Awesome product!
