Yeah, I don't know why people don't use hypoallergenic detergent for their masks. I use All Free and Clear. AND I rinse it thoroughly. Another note: a poster on WS had me convinced that satin would be too hot so I went for silk. Well, I finally tried a satin lining and it is not hot. It is breathable. And it is good protection as an inner layer. So don't hesitate to use it if you have skin irritation. It's also hella cheaper (and more humane) than silk.
