How to Wash a Horse Blanket (A Step-by-Step Guide)

If you keep horses in North Idaho — whether you’re out near Priest River, down in the Pend Oreille valley, or anywhere around Bonner County — you know what a horse blanket looks like after a long winter. Mud, manure, sweat, hay. It’s not subtle.

Washing a horse blanket at home is often not realistic. They’re heavy, bulky, and most home machines simply aren’t large enough to handle the job. Trying anyway can damage your machine — and still leave you with a half-clean blanket. Here’s how to do it right, and what to expect when you bring one in.

Before You Wash: Prep Work Matters

A little prep time outside saves a lot of trouble at the laundromat. Do these steps before loading up your truck:

• Shake it out thoroughly. Remove as much loose hay, dirt, and debris as you can. A stiff brush or rubber curry comb works well for embedded hair.
• Pre-treat heavy soiling. If there are serious stains — manure or deep mud — a quick pre-soak with a mild detergent or horse-specific cleaner like Nikwax Rug Wash can help.
• Check for damage. Washing a blanket with torn seams or broken buckles can make things worse. Do a quick inspection first.
• Close all straps and buckles. Loose hardware can snag in the drum and damage the blanket or the machine.

What Kind of Blanket Do You Have?

Not all horse blankets are the same, and the washing method depends on what you’re dealing with:

• Turnout blankets (waterproof shell): These have a DWR (durable water repellent) coating that needs to be protected. Use a technical cleaner — not regular detergent. Fabric softener will ruin the waterproofing.
• Stable blankets (non-waterproof): More straightforward. A mild detergent, warm water, and a gentle cycle work well.
• Fly sheets: Usually lighter mesh material. These can often go through a standard large washer on a gentle cycle without issue.

The Washing Process

1. Load the blanket into a large-capacity front-loading washer. These machines handle bulk without the agitator damage you get in top-loaders.
2. Use the appropriate detergent for your blanket type. For waterproof turnout blankets, use Nikwax Rug Wash or a similar tech wash.
3. Select a warm or cold gentle cycle — never hot, which can break down waterproof coatings and shrink materials.
4. Run an extra rinse cycle to fully remove detergent residue, which can irritate your horse’s skin.
5. Check that it’s fully spun out before moving to the dryer. A soaking wet blanket takes a very long time to dry.

Drying a Horse Blanket

Most horse blankets should air dry rather than go into a dryer. High heat can delaminate waterproof membranes and warp hardware. If the blanket is just a stable blanket without waterproofing, a low-heat dryer cycle is generally safe — but check the care label first.

If you’re air drying, hang it over a fence rail or a couple of sawhorses so air can circulate underneath. Don’t lay it flat on the ground.

Re-Waterproofing After Washing

Every few washes, a waterproof turnout blanket benefits from a fresh coat of DWR. Products like Nikwax Rug Proof or Grangers Clothing Repel can be applied in the dryer or sprayed on after washing. This restores the beading effect and extends the life of the blanket considerably.
