Why are polyester suits dry clean only? Other types of polyester clothes can be washed in the washing machine, why is it advised not to wash polyester suits in the washing machine though?
I understand that 100% wool cannot be washed in the machine but I don’t get how 100% polyester or something like a 80/20 poly-wool mix couldn’t be washed in the machine.
And we don’t want a discussion about how polyester sucks in this thread. We all know that it is bad compared to wool and other natural materials but that is not the point of this thread.
