How to Clean Baseball Caps in the Dishwasher
Baseball caps are a staple accessory for many—whether you’re shielding your eyes from the sun, rooting for your favorite team, or just adding a casual vibe to your outfit. But with frequent wear, they inevitably collect sweat, dirt, and grime. While hand-washing is often touted as the safest method, washing baseball caps in the dishwasher is a popular hack that can save time and effort, especially if you’re cleaning multiple hats at once. This detailed guide will walk you through the process step-by-step, offer practical tips to avoid damage, and provide additional insights to keep your caps looking fresh. Let’s dive in!

Why Use a Dishwasher to Clean Baseball Caps?
Cleaning a baseball cap in the dishwasher might sound unconventional, but it’s a method embraced by many for its convenience and ability to tackle multiple hats simultaneously. Unlike a washing machine, which can tumble and distort the cap’s shape, a dishwasher keeps the hat stationary on the rack, minimizing friction. Plus, it’s a hands-off approach—perfect for busy schedules. However, it’s not without risks: high heat and harsh detergents can fade colors or warp the bill. With the right precautions, though, this technique can be a game-changer.
As noted by Taste of Home, “Baseball cap brands will never officially suggest you wash a cap in the dishwasher, but it’s a popular hack and worth a try if you want to give your hat a deep clean.” [(( Taste of Home ))] This method shines when you need a thorough clean without the elbow grease of hand-washing.

Step-by-Step Guide to Cleaning Baseball Caps in the Dishwasher
Here’s how to do it right, based on expert advice and tried-and-true methods from credible sources.
Step 1: Check the Hat’s Material and Care Label
Before you even think about the dishwasher, inspect your cap. Look inside for the manufacturer’s care tag, which will indicate the material (cotton, polyester, wool, etc.) and washing instructions. “Materials like cotton or synthetics are safe to put inside your dishwasher, but cardboard or wool could get damaged,” advises a Quora contributor with practical cleaning know-how. If the tag says “hand wash only,” skip the dishwasher—vintage hats (pre-1983) often have cardboard bills that will disintegrate when soaked.
Flick the bill with your finger: a hollow sound suggests cardboard, while a solid feel indicates plastic. Modern caps typically use durable plastic bills, making them dishwasher-friendly if handled carefully.
Step 2: Pre-Treat Stains
For heavily soiled hats—think sweat-stained sweatbands or dirt-smudged brims—pre-treating boosts results. Practically Functional recommends, “To get the best results when washing baseball caps in the dishwasher, you should pre-treat the sweatiest parts of the hat with a laundry pre-treater. I made a simple paste using a little bit of Biz and warm water and gently scrubbed it into the sweatband and back of the hat using a stiff bristle brush.” [(( Practically Functional ))] Alternatively, dab a mild detergent like Woolite onto stains with a soft toothbrush and let it sit for 10-15 minutes.
Step 3: Secure the Cap in the Dishwasher
Placement is key to preserving shape. Place your cap on the top rack of an empty dishwasher—away from the intense heat at the bottom. WikiHow suggests, “Place the hat on the top rack of your empty dishwasher, propping it on the prongs to protect its shape.” For extra protection, use a cap frame or holder (available online or at sporting goods stores). These plastic cages snap around the cap, ensuring it stays structured during the cycle. If you’re washing multiple hats, space them out to avoid overlap.
Step 4: Choose the Right Detergent
Dishwasher detergents can be harsh, often containing bleach or acidic additives that harm fabrics. “Many dishwasher detergents contain bleach, so be sure that you are using a detergent that doesn’t contain bleach. And lemon-scented detergent should be avoided as well; the acidity in the added lemon scent can be harmful to your hats,” warns Practically Functional. Opt for a gentle, bleach-free option like a tablespoon of Borax, a non-bleach cleaner, or a dishwasher pod designed for delicates. WikiHow advises, “Fill the detergent compartment with 1 tbsp of Borax or non-bleach cleaner, but don’t put laundry detergent into your dishwasher.”
Step 5: Set the Wash Cycle
Run the shortest, coldest cycle available—think “quick wash” or “light wash.” High heat can shrink fabric or melt plastic components, so if possible, disable the heated drying cycle. “Run the shortest, coldest cycle possible on your dishwasher, and turn off the heating cycle if you can,” instructs WikiHow. [(( WikiHow ))] This gentle approach minimizes risk while still cleaning effectively.
Step 6: Remove Before Drying
Take the hat out immediately after the wash cycle ends—before the drying phase kicks in. “If you can’t turn off the drying cycle in your dishwasher, make sure to take out your hat before it starts. The heat could cause your hat to shrink or melt any plastic pieces your hat may have,” cautions WikiHow. The cap should feel damp but not dripping.
Step 7: Air Dry Properly
Drying is where shape preservation happens. “Once the dishwasher is done washing the baseball caps, pull them out and set them aside to dry. I propped them up on the counter on top of a tumbler to help them keep their rounded shape a little bit,” shares Practically Functional. Alternatively, place the cap over a small bowl, jar, or balled-up towel to mimic the head’s curve. Avoid direct sunlight or heat sources like radiators, which can fade colors or stiffen fabric. Let it air dry in a well-ventilated spot for several hours—patience pays off here.

Tips to Avoid Damage
- Test for Colorfastness: Dab a wet cloth on an inconspicuous spot (like inside the sweatband) and check for color bleeding. If color transfers, hand-wash instead.
- Skip Vintage Hats: Pre-1983 caps with cardboard bills are a no-go. Spot-clean these treasures instead.
- No Dishes Allowed: Run the dishwasher with hats only—food residue or greasy plates can transfer grime.
- Use a Cap Washer: For prized hats, invest in a cap washer frame to lock in shape. Nike notes, “If you’re worried about your hat losing its shape in the dishwasher, you can buy a cap washer to protect both the bill and the cap itself.” [(( Nike ))]

Pros and Cons of the Dishwasher Method
Pros
- Time-Saver: Clean multiple caps in one go without scrubbing.
- Less Agitation: Unlike washing machines, there’s no tumbling to distort the bill.
- Deep Clean: The water jets tackle sweat and dirt effectively.
Cons
- Heat Risk: High temperatures can shrink or fade hats if not controlled.
- Detergent Concerns: Harsh chemicals may damage fibers or colors.
- Not Universal: Delicate or vintage hats don’t fare well.
Whirlpool warns, “It’s not recommended to wash a baseball cap in the dishwasher. While you may have heard that it’s okay to clean a hat in the dishwasher, the high heat and harsh, bleach-based dish detergents can damage fibers and remove color from the hat.” [(( Whirlpool ))] Weigh these factors based on your cap’s value and condition.

Alternative Cleaning Methods
If the dishwasher feels too risky, consider these options:
- Hand-Washing: Soak in cool water with mild detergent for 15-30 minutes, scrub stains with a toothbrush, rinse, and air dry. It’s the gold standard for control and safety.
- Washing Machine: Use a mesh bag, cold water, and a gentle cycle—but only for sturdy, modern caps with plastic bills.
- Spot Cleaning: For minor stains or vintage hats, dab with a damp cloth and detergent, then blot dry.

How Often Should You Clean Your Cap?
Frequency depends on use. “If you wear your cap every day or even a few times a week, plan to wash it at least once a month,” suggests Good Housekeeping. Daily wearers, especially in hot weather, might need weekly cleans to banish sweat and odor. For occasional use, a few times a year suffices. Don’t wait for visible stains—regular maintenance extends your cap’s life.

Not if you secure it on the top rack or use a cap frame and skip the heat cycle. Air drying over a rounded object helps maintain structure.
What detergent is best?
Use a gentle, bleach-free option like Borax or a delicate-safe dishwasher pod. Avoid standard dishwasher detergents with bleach or citrus additives.
How do I dry it without a cap frame?
Place it over a small bowl, jar, or balled-up towel to mimic your head’s shape. Let it air dry away from heat or sunlight.
Can I wash dishes and hats together?
No. Run an empty cycle to avoid cross-contamination from food residue or grease.
