How do you wash a horse blanket?

From Tack of the Day research — based on questions riders are asking across equestrian communities this week.

Washing a horse blanket requires removing caked-on mud, securing all hardware, and using a front-loading washing machine or a heavy-duty hose with a blanket-safe detergent. Never use harsh household detergents or hot water, as these will strip the waterproof coating and ruin the fabric.

Prepping the Blanket for the Wash

Before you even think about water, you must remove the bulk of the dirt. Hang the blanket over a sturdy fence and use a stiff dandy brush to scrape away dried mud, manure, and loose hair. Doing this prep work in the freezing cold can be brutal on your hands, so wearing a pair of Classic Equine Heavy Duty Barn Gloves - Grey 3-Pack Winter will keep your fingers warm and protected while you scrub. Once the heavy debris is gone, fasten all the chest buckles, belly surcingles, and leg straps. Loose metal hardware can dent your washing machine drum or tear the blanket fabric during the cycle. For extra protection, place the secured straps inside clean socks or put the entire blanket inside a large mesh wash bag.

Washing and Drying Safely

To preserve the waterproof membrane of turnout blankets, always wash them in cold water. Use a specialized equestrian blanket wash or a mild, dye-free, fragrance-free detergent. Avoid standard household detergents, fabric softeners, and bleach, as they break down the technical coatings. A commercial front-loading washing machine at a laundromat is ideal because it lacks a center agitator, which can easily catch and rip straps. If you must wash at home without a front-loader, spread the blanket on a clean concrete pad or hang it over a hitching rail, scrub it by hand with a soft brush and soapy water, and rinse thoroughly with a hose.

Never put a waterproof horse blanket in a dryer. The high heat will melt the waterproof backing and ruin the blanket permanently. Instead, hang the blanket to air dry in a well-ventilated area out of direct, harsh sunlight. While your horse's heavy turnout is drying, you can keep them comfortable in the stable with the Weaver Leather Fleece Cooler - Moisture Wicking Horse Sheet, which prevents chills after grooming or bathing.

Post-Wash Inspection and Health

Once the blanket is completely dry, inspect the lining and outer shell for any tears that need repairing. If water no longer beads on the outer shell, apply a spray-on waterproofing treatment designed for outdoor gear. Ensure the blanket is 100% dry before storing it in a sealed bin to prevent mold and mildew. Remember that dirty, damp blankets can harbor bacteria and fungi that cause skin irritation. If your horse shows signs of skin infections, hair loss, or irritation after wearing a blanket, consult your veterinarian to rule out underlying health issues.
