In all weathers, they keep us horses warm. It is important to regularly clean blankets and rid them of all mud, grass, sweat and any other dirt. Before washing on first, brush or spray all the loose dirt off the blanket, neck piece or mask as much as possible. Blankets are best washed at 60 degrees, this will kill all bacteria, dust mites and lice. Check the washing label to see if your blankets can handle this. After a wash, you will have nice clean blankets again!
