Your favorite cap has a sweat ring on the band and a bill that's gone soft, and you're afraid to wash it because you've seen what a washing machine does to a brim. A hat washer is a plastic cage that holds the cap's shape while it goes through the washer or the dishwasher. Here are the 4 best hat washers in 2026, ranked by rating and review count.

We're going by the listings and buyer reviews. We didn't test them ourselves. They're all cheap, so the choice comes down to how many hats you wash and how you plan to wash them.

What to Look For in a Hat Washer

Single or multi-pack. If you only have one or two caps, one cage is enough. If everyone in the house has a cap, a 2 or 3 pack is cheaper per cage.

Washer, dishwasher or both. Most say they work in both, usually on the top rack of the dishwasher. Check the listing if you have a top-loader with an agitator, since a few brands say not to use theirs there.

Size and fit. A cage that's too small squeezes the crown, and one that's too big lets the cap flop. Look for adult and kid sizes, and flat or curved bills.

Material. Hard plastic (polypropylene) holds its shape better than thin wire. Skip hot water, since it can warp the plastic and the hat.

Storage. Some cages double as a hat rack. If you're tidying a laundry room at the same time, see our laundry room folding table picks.

How to Wash a Hat With a Hat Washer

  1. Brush off dust and spot-treat any sweat stains with a little detergent.
  2. Snap the cap into the cage so the bill sits in its slot.
  3. Put it in the dishwasher top rack or the washer with other laundry, on a gentle cycle with cold or warm water.
  4. Skip the dryer. Take the cap out and let it air dry in the cage.
  5. Once it's dry, take it out of the cage.

Frequently Asked Questions

How do hat washers work?

The cage holds the crown and bill in shape, so the cap doesn't get crushed or bent while it's washed. Water goes through the frame and cleans the fabric.

Can you wash a hat in the dishwasher?

With a hat cage, yes, on the top rack and without heated dry. Check the cage's listing, since some are washer-only.

How do you wash a hat without ruining the bill?

Use a cage, wash on a gentle cycle, use cold or warm water and air dry. Heat and tumbling are what bend the bill.

Do hat washers work?

Reviews are strong on the best-sellers. They keep the shape, though they won't remove every stain, so spot-treat sweat marks first.

Final Thoughts

For most people we'd buy the BallcapBuddy. It has by far the most reviews and a solid 4.5-star rating. The YEENOR is a good cheaper alternative if you want something that also hangs in a closet.

If you've got kids or a pile of caps, the Eiito 2-pack or the Der Rose 3-pack are better values per cage. Just keep the Eiito out of an agitator top-loader.
