How to Clean Sweat Stains From a Hat

Introduction

Sweat stains can quickly build up on hats, leaving behind yellow marks and unpleasant odors. Cleaning them properly helps extend the life of your hat while keeping it fresh and wearable.

What You'll Need

• Mild laundry detergent or dish soap

• Warm water

• Soft-bristle brush or old toothbrush

• Clean cloth or sponge

• Baking soda (optional)

• White vinegar (optional)

Steps

Check the care label to make sure the hat can be hand washed.
Fill a basin with warm water and add a small amount of mild detergent.
Soak the hat for 15–30 minutes, focusing on the sweat-stained areas.
Gently scrub the stained areas with a soft brush or toothbrush.
Rinse thoroughly with cool water to remove all soap residue.
Pat the hat with a towel and reshape it before air drying.

Alternative Methods

• Use a baking soda paste to lift stubborn yellow sweat stains

• Dab white vinegar on sweat bands to neutralize odor before washing

• Spot clean only the sweat band if the rest of the hat is clean

What NOT to Do

• Do not put hats in the dryer, as heat can warp their shape

• Do not use bleach, which can damage fabric and discolor hats

• Do not wring or twist the hat aggressively
