Wool Hats & Caps Washing Guide – The Right Way

If you’re here, you might be experiencing either one of these situations; something might have gone wrong when you washed your wool cap, or you still haven’t washed your favorite wool cap since you bought it. Whatever it may be, we appreciate you taking the first step to know how to wash a wool hat.

Before diving into the best method to clean your wool hat, it’s important to understand the material- wool and how you should not wash your wool cap and hats.

What Is Good and Bad About Wool fabric?

As everyone already knows, wool fabric is nothing but the natural fibers from the fleece of goats, sheep, and rabbits manufactured into textile fibers to keep us warm in cold temperatures.

Undoubtedly, wool is second to none for the ultimate warmth and thermal insulation when worn.  Not like any other fibers, even when you’re stuck in a heavy downpour or sweating excessively, wool has excellent moisture-wicking properties to wick away moisture from your body and keep it dry. Additionally, Australian scientists have found wearing wool helps you to sleep better.

The downside of wool is, they are a little tricky to wash. They hold an increased risk of damage and shrinkage when washed without knowing how to wash a wool cap. Secondly, the shocking holes you can notice in your wool cap if you don’t store it properly. Clueless? We are speaking about the pesky fabric-eating bugs.

Can You Wash Wool Hats?

Of course, like any other synthetic caps, wool baseball caps, beanies, and berets can be washed too. But, wash them less frequently when compared to polyester, acrylic, and cotton caps.

Accidental stains, when not treated immediately, can be transformed into permanent stains. If you’re a daily wearer, hand wash them at least once a week. Or else, you can machine wash them safely according to our guide for two to three times in a season.

Wool Hats and Caps Washing Guides

What to Know Before Cleaning a Wool Hat

1. Check The Care Label First

Some caps are hand washable; some allow machine washing, and some prefer to be dry clean. Not all manufacturers produce caps in the same process, even if they are all wool made.

It depends on what type of wool they are made up of; merino or cashmere or angora or alpaca wool or blended; check the care instructions of the cap. 

2. No Usage of Enzyme Based Heavy Duty Detergents

It’s important to check what kind of detergent you’re using. Even if it’s a single wash, heavy-duty detergents which contain bleach and enzymes can leave residue on the delicate fibers of your wool cap and cause pilling.

Instead, always go for a mild detergent that is specially formulated for wool.

3. Avoid Washing in Hot Water, Hot Temperatures, and Tumble Dry

Washing your wool cap in high temperatures and hot water may cause shrinkage and wrinkles on your wool cap. If you want to disinfect your wool cap, sink it in a tub of still warm water.

Make sure you don’t apply any motion to your cap while it’s soaking. Wool in warm water can shrink more in motion. We do not recommend tumble dry for wool. The increased heat, overload, and tumbling motion can deteriorate the quality of your cap and ruin the shape.

4. Don’t Wring or Twist It.

After washing, do not wring your cap to expel the water for drying. Once it’s damaged, it’s damaged. Wringing and squeezing wool can damage its fine fibers and ruin the shape of your favorite cap.

Instead, gently press the water from the cap and let the cap dry flat on a fresh towel.

5. Don’t Use Chlorine Bleach.

Even if you have a white cap in hand, do not use bleach on wool fibers. Despite what you might come across, bleach is a mind-blowing stain remover; but, according to research, its sodium hypochlorite compounds can attack the fine wool fibers, and unfortunately, it can cause yellowish, irreversible discoloration.

  1. Turn the cap inside out after every use and leave it to breathe fresh air. Do not dry them in sunlight, as it will fade the cap.
  1. Ensure you clean and store the cap and hats properly in airtight bags, containers, or cedar drawers at the end of the season.
