> We tell customers to wash their outerwear, regardless of whether it has PFAS or not, after every three to five significant uses and to re-waterproof every three to five washes.

Their outerwear? So we're not talking about inner layers here. All of them? Every three to five uses?? I have jackets and coats that are decades old, in active (seasonal) use for the whole time, that I have never washed. Is this unusual? How would you even wash them? For some of them, it seems like just throwing them in a washing machine would damage the surface layers, make the lining lumpy, shrink them, or do some other problematic thing to them.
