How to clean a baseball cap

May 20, 2025

Is your trusty baseball cap looking a little rough? It's been your go-to for sun protection and bad hair days, but now it might need some extra care to look and feel its best. Let us show you how to clean your cap, whether by hand or in the washing machine. And no, we do not recommend using the dishwasher, despite what you might have seen on TikTok!

Preparation

Before you start cleaning your baseball cap, it's crucial to check what the visor is made of, as this will determine the best cleaning method. For older caps with a cardboard visor, avoid soaking or machine washing to prevent damage.

Inspect the cap for stains, paying special attention to the sweatband. Apply a small amount of mild detergent or stain remover to any visible stains and gently rub it in. Let it sit for 10-15 minutes before cleaning.

Hand washing baseball caps

Hand washing is a gentle and effective way to clean your baseball cap. Start by filling a basin with lukewarm water and adding a small amount of mild dish soap. Submerge the cap and let it soak for 10-15 minutes to loosen dirt and grime.

After soaking, use a soft toothbrush or microfiber cloth to gently scrub any dirty areas, paying extra attention to stains. Once you've scrubbed the cap, rinse it thoroughly with cool water to remove all soap residue. This method ensures your cap is cleaned without causing any damage to the fabric or structure.

Machine washing baseball caps

Machine washing your baseball cap is possible, but it's important to do it correctly to avoid damage. A front-loading washing machine is recommended, as the agitator in top-loading machines can be too harsh on caps.

Laundry detergent

Use a gentle detergent designed for lower temperatures. This will help preserve the fabric and colors of your cap. Be mindful not to overdo the detergent; a little goes a long way. Excess detergent can leave residue, which may cause staining on the cap.

Wash program

Select a wash program with lower temperatures and place your cap in a mesh laundry bag to protect it. Wash it together with similar colors, but avoid overloading the machine. Choose a gentle cycle to ensure your cap is cleaned without being damaged.

Drying baseball caps

Proper drying is essential to maintain the shape and integrity of your baseball cap. Start by patting the cap dry with a microfiber cloth to remove excess water. To help it retain its shape, stuff the cap with a towel or crumpled newspaper. Avoid using a tumble dryer, as the heat can warp the cap and damage the fabric. Instead, let the cap air dry in a well-ventilated area, away from direct sunlight and heat sources.
