How To Wash Baseball Cap: Apparel Care Technique

If you frequently wear a baseball cap, it’s likely to accumulate both the appearance and scent of regular use. Periodic, gentle cleaning is essential to eliminate dirt and sweat stains. The frequency of cleaning may vary, ranging from a weekly routine to a couple of times a year, depending on how often you wear the cap.

A key guideline is to avoid using the washing machine and dryer, as both are suboptimal for cleaning baseball caps. Additionally, steer clear of products containing bleach. Here’s a comprehensive guide to everything you need to know about keeping your baseball cap in top shape.

This article contains useful tips on how to wash a baseball cap; carefully read through.

Things To Know Before Washing Your Baseball Hat

Before you begin cleaning your baseball cap, here are some tips to consider:

  • Baseball caps can be washed in the washing machine as long as the brim is not made of cardboard.
  • Does my hat have a cardboard or plastic brim? To find out if your hat has a cardboard brim, simply flick the brim—if it makes a hollow sound, it’s likely made of cardboard. Cardboard was used in vintage hats manufactured before 1983, so if your hat is newer, you probably don’t need to worry.
  •  You should not put your baseball cap in the dryer, otherwise, it could shrink and become misshapen. Instead, let the hat air dry by hanging it up or laying it on a towel.
  • If your hat has a stain that doesn’t warrant a complete wash, you can swiftly eliminate it using a fabric-safe stain removal solution such as OxiClean. Just spray the product on the stain, allow it to sit for a few minutes, and then blot it dry with a damp cloth or towel. For caps with embellishments like rhinestones or embroidery, it’s advisable to delicately brush those areas with a toothbrush to assist in stain removal.
