I clean and repair horse blankets for a living I am in Newberg Oregon. Robin's Equine Service. Lots of rain and mud here. I have a 50 lb commercial washing machine. I can put two smaller blankets at once in it. Some laundry mats will let you do horse blankets some won't. Here is the important part Do Not Use Detergent on your turn out blankets It will ruin them and hang to dry.
