Quick answer

Hand wash your knit pom pom cap in cold water with mild detergent, reshape it while damp, and store it flat in a cool, dry place to prevent stretching and pilling.

Why hand washing beats machine washing

Knit caps, especially those with acrylic blends and pom poms, can lose their shape or develop pilling in a washing machine. The agitation and heat can also loosen the pom pom attachment or cause the acrylic fibers to become scratchy. Hand washing gives you full control over the process and extends the life of the cap.

When to clean your cap

You don't need to wash your winter beanie after every wear unless it's visibly dirty or sweaty. Over-washing wears down the fibers faster. Spot cleaning small stains with a damp cloth and mild soap is often enough between full washes.

Step-by-step care routine

  1. Fill a basin with cold water and mild detergent: Use a sink or small basin. Cold water prevents shrinking and color bleeding. Add a teaspoon of gentle laundry detergent or wool wash. Swish to dissolve. Hot water will shrink acrylic knits. Always stick to cold.
  2. Submerge and gently squeeze the cap: Press the cap into the water and let it soak for 10–15 minutes. Gently squeeze the fabric—do not twist or wring, which can distort the knit and loosen the pom pom. Twisting can permanently stretch the ribbed hem. Squeeze only.
  3. Rinse in cold water until soap is gone: Drain the soapy water and refill with fresh cold water. Submerge and press the cap several times. Repeat until no suds remain. Avoid running water directly on the pom pom. Residual detergent attracts dirt and makes the cap feel stiff.
  4. Remove excess water with a towel: Lay the cap flat on a clean, dry towel. Roll the towel up and press gently to absorb moisture. Unroll and remove the cap—it should be damp, not dripping. Never use a spin cycle or wring the cap. The towel method is safe.
  5. Reshape and air dry flat: Place the damp cap on a drying rack or second dry towel. Shape the crown, brim, and pom pom with your hands. Let it air dry away from direct sunlight and heat sources. Do not hang it—gravity will stretch the wet knit. Hanging a wet knit cap creates a droopy, misshapen crown.
  6. Store flat or loosely folded in a drawer: Once fully dry, fold the cap loosely and place it in a drawer or on a shelf. Avoid cramming it into a tight space or stacking heavy items on top. For longer storage, use a breathable cotton bag. Stretching over a hook or hanger can deform the ribbed hem over time.
