How to Wash your Cap Without Ruining It

Caps are a great accessory for style, sports, and sun protection, but they can collect sweat, dirt, and odors over time. Washing them correctly ensures they stay fresh and keep their shape. Here’s the best way to clean different types of caps—without damage. It's 2025 already and time to wash your cap!

1. Check the Material First before you wash your cap

Different caps require different care methods. Here’s how to treat each type:

Cotton & Polyester Caps – These are the easiest to clean and can usually handle gentle machine washing or hand washing.
Wool Caps – Wool is delicate, so use a special wool detergent like re:CLAIM Wool Wash and wash by hand. Never use hot water!
Performance & Sports Caps – Many modern caps are made from moisture-wicking fabrics. A sports detergent like re:CLAIM Sport Wash removes sweat and odors effectively.
Vintage or Structured Caps – Older or stiff-brimmed caps should always be hand-washed to prevent damage.

2. Hand Washing – The Safest Method to clean a cap

Hand washing is the best way to clean a cap without ruining it. Here’s how:

Fill a basin with lukewarm water and add a small amount of re:CLAIM detergent, suited to your cap’s material.
Let the cap soak for 15–30 minutes to loosen dirt and sweat.
Use a soft brush or cloth to gently scrub stained areas, especially the sweatband.
Rinse thoroughly with cold water.

3. Can You Machine Wash a Cap?

If the care label allows, you can machine wash your cap on a gentle cycle with cold water. Place it inside a wash bag or pillowcase to protect its shape. Avoid using strong detergents—stick to mild options like re:CLAIM.

4. Drying a cap – Avoid Heat!

Never put your cap in the dryer! Heat can warp the brim and shrink the fabric. Instead:

Air dry naturally by placing the cap over a rounded object (like a bowl) to keep its shape.
Avoid direct sunlight, which can cause fading.

5. Spot Cleaning for Quick Fixes of your dirty cap

For small stains, use a damp cloth and re:CLAIM detergent to gently clean the affected area without fully soaking the cap.

By following these simple steps, your cap will stay clean, fresh, and in perfect shape for longer. Need the right detergent? Check out re:CLAIM’s specialized range for all fabrics!
