This is a brief of the whole washing process. Now let us explain the detailed process to make it easy, effective, and harmless.
Tools
You need some tools to wash your favorite hats easily and without hampering them. The tool list is given below:
- A dishwasher
- Dishwasher detergent that is bleach-free and the scent is mild except lemon flavor.
- Stain Remover
Here is the step-by-step guide to washing baseball caps in the dishwasher.
Prepare the Hat
Okay, this step is optional. It depends on your hat condition. If your baseball caps are extremely dirty and get a stain from environmental substances, then you must prepare your hat before putting it into the dishwasher.
A little pre-treatment is enough to prepare your hat for the final wash.

Pre-treating enhances the efficiency of your wash cycle and ensures a better result of washing.
You can spray or apply the paste on the soiled or stain area of the hat. Keep it for 30 minutes to give the laundry time to break down the soil and stain.
Use a soft brush to scrub gently to erase the stubborn stain. You can also mix a few drops of vinegar with paste if the stains are too dark. Now your hat is ready for the final wash.
Load baseball cap into the dishwasher
While you are loading the cap, it is important to maintain the shape of the cap. Otherwise, a wrong placement can destroy the shape of your favorite hats.
So you can use the plastic frame to place the cap inside the frame that maintains the structure of your caps.
But if you don’t want to buy an extra plastic frame, then keep the baseball caps on the top rack of the machine. Then fix the cap near the upright hob by connecting the cap with a clothespin near the adjustable strap and rack.
Depending on your rack size, you can fit a various number of caps in the top rack to wash at a time in the dishwasher.
Apply detergents
Now it’s time to pour the right amount of detergents. You must avoid harsh detergents that contain bleach, toxicity, or sharp scent.

This type of detergent can damage the fabric of the cap. Pour the standard amount of your favorite detergents into the dispenser of the dishwasher and close the door.
Washing
Choose the normal wash cycle and use warm water without drying time. Then switch on the dishwasher.
Remove the cap
Give the dishwasher time to complete the cycle. When the cycle is finished, take out the cap.
Dry the cap
After washing the cap now, you need to hang the baseball cap using a Pant hanger. Use the adjustable strap to clip the cap to the pants hanger.
Place it in an area where it gets proper airflow and ensure you maintain the shape while keeping it dry. You can also use a bowl that is a similar size to your cap to manage the shape of your cap.
Things to consider
You must consider some major factors before jumping into the washing process to avoid damage.
Types of cap brim
Here we will talk about different types of cap brim. You must consider the brim type to choose the right method of washing.

Cardboard brim cap
Baseball caps that come with a cardboard-supported brim are a traditional or old type of model. This type of cap is only suitable for spot cleaning. You can’t sink this cap into water that can ruin the brim.
Tap the brim and check whether it makes a hollow sound to make sure whether the cap is made of cardboard brim or not. You can also check the tag to know your brim types.
Plastic supported brims cap
Most of the modern baseball caps come with plastic-supported brims. That allows machine wash. You can easily wash those baseball caps in the dishwasher, washing machine, etc. Manual cleaning is also fine with this modern plastic brims cap.
Color test
It is essential to test the baseball cap fabric before placing it onto the dishwasher.
Mix a little bit of detergent with water and apply it on a small part of the hat. If it releases any color then don’t wash it with detergent. So you should wash it only in warm water.
Settings
When you wash the hat in the dishwasher, never select high heat or harsh detergents. That can damage the fibers and color of your favorite cap.
How to spot clean a hat
If you have cardboard brim baseball caps, then you must avoid machine wash. Follow the below steps.
- Apply any laundry detergent that is free from bleach into warm water.
- Give the mixture time to dissolve properly
- Use a clean towel and sink it into the mixture.
- Then use the wet towel to gently rub the cap to remove dirt, grime, and stain. Remember, you can’t soak the brim; just gently rub it with the towel.
- If it contains a tough stain, then you can use a soft brush to remove the stain.
- Rinse the cap with the towel to wipe the detergent
- Keep the heat on the cabinet for airdrying
