You’ve probably heard a couple of different ways of how to clean a baseball cap. Some might tell you that handwashing is the way to go. Others swear by dishwashers. Others still suggest that you can’t go wrong with a wash machines.

Here’s the thing: dishwashers and washing machines can cause problems, but handwashing is pretty safe. So, the recommended method is hand washing. It’s a simple and straightforward process.

Start with a stain-fighting laundry pretreatment. Add as much as you want until you feel like you’ve pretreated the cap enough. Make sure you focus on stains and areas that see a lot of sweat, like the band around the head.

Fill your sink with warm water and add a small bit of laundry detergent. Agitate the water to make it soapy, and soak the cap for up to three hours, working the water into the fabric. Use a clean cloth or a toothbrush to work the sudsy water into the cap.

After three hours, rinse the cap well with clean, warm water.


If your hat has a sticker you want to keep, cover it with plastic wrap. Use a toothbrush dipped in warm water mixed with bleach-free detergent to gently scrub any problem areas of the baseball hat.

Preserving Color

Follow these tips on how to wash a baseball cap without losing the color.

If you’re concerned about changing the color of your baseball cap, use a damp white washcloth with a little bit of detergent on an inconspicuous part of the cap, like under the brim.

Rinse with a clean damp washcloth and let dry. You are safe to clean your hat if there is no color change; if the color does change, you should only use water to wash your cap.

Cardboard forms must be only spot cleaned. For sweat stains on the inner band, use a bit of shampoo on a damp washcloth.
