The cleaning instructions we have on our bags are required to be there and are specific to non agitator, large front load style, on delicate. Unfortunately even following these instructions carefully can cause down migration and internal damage to the seams of your sleeping bag.  We recommend spot cleaning your bag before risking damage by fully washing the bag.  Due to the risk involved in washing your sleeping bag, damage caused in that process is not covered under our warranty. If is smells like smoke leave it outside for the day to air out but typically bags are not meant to be washed very often to keep their temperature rating and quality over the years. Please refrence the articles in our knowledge base for the best washing instructions.
