When Should You Often Wash Baseball Caps?

Laundry time can be confusing when it comes to wool caps and hats. Here’s when to wash your baseball cap to enjoy long-lasting usage.

  • If your ball cap is your favorite, and you wear it every day, wash it at least once or twice a week. Handwashing is the best method when you’re an everyday wearer.
  • Wash them two to three times in a season if you’re not a frequent wearer of the cap.
  • If you notice any accidental stains, spot clean them immediately with a brush or sponge using a delicate stain remover formulated for wools.
  • Make sure you wash them when you’re going to store them for a long time until the next season to prevent moths, silverfish, and carpet beetles from living on your cap.

What to Know Before Cleaning a Wool Hat

1. Stay Away from Enzyme Based Detergents

Be sure not to wash your wool baseball cap with an enzyme-based, heavy-duty detergent. Detergents with enzyme ls and bleach will slowly start to destroy the proteins and deteriorate the quality of your cap.

2. No Chlorine Bleach

Avoid using chlorine bleach even if you have got a white cap. According to the journal of advanced research, chlorine bleach can yellowish your wool fibers and can cause irresistible stains.

3. Don’t Wash Them in Hot Water with Motion

According to a SIFO study, wool garments can even be boiled in hot temperatures to disinfect them. But they have to stay still during the whole process since wool shrinks when you’re combining hot water with motion.

4. Never Set the Temperature High in Washing Machine

Remember, high heat with motion can shrivel up and shrink the delicate fibers of the wool. The average temperature to wash any wool cap should be 20°C to 30°C. The cooler, the better. You can also use the wool setting in your washing machine to wash your wool cap.

5. Don’t Tumble Dry

Tumble dry is a big no-no when it comes to drying your caps. According to research, the increased temperatures and machine agitation can ruin the shape of your structured baseball cap. Whether hand-washed or machine washed, let the cap air dry without being exposed to direct sun rays.

6. Check Your Visor

Last but not least, don’t forget to check the material of your visor before submerging into water. Vintage caps are mostly stitched with cardboard brim, which can ruin when immersed in water. 

Tap the brim of the cap and check whether it’s made up of cardboard.

If it is cardboard, you have no other choice than to spot clean them. You can also treat them with baking soda to remove the odor. If it is made up of plastic, you can wash them.
