Sometimes it's possible to wash a horse blanket in a home washing machine. One of the best secrets for washing horse blankets in a washing machine at home is covering the buckles and hardware with fabric. We use socks, attached to the horse blanket with just a few stitches with upholstery thread. Takes about five minutes -- can save a lot of wear on our washing machine! Gather up any straps that hang loose -- like the surcingle strap. Place the the stock over the entire length and stitch the sock toward the base of the strap. This saves wear and tear and will also prevent the strap from getting twisted around the sheet or horse blanket in the wash.
