Tested Baseball Caps Accessories and Attachments 2026

Overview

I've ruined more expensive hats than I care to admit. That's exactly why I started testing different baseball caps accessories and attachments to see what actually works. This section covers the specific tools, cages, and brushes you need to clean fitted caps, snapbacks, and dad hats without destroying the brim. We'll look at dishwasher cages, washing machine forms, and hand-washing brushes. If you sweat through your favorite New Era 59FIFTY during a summer baseball game, you need the right gear. I'll share my exact setup for keeping hat collections spotless. Grab a coffee, and let's look at the gear that actually saves your headwear.

Key Information

Let's talk about the actual gear. Most people just throw a hat in the washing machine and pray. Don't do that. The cardboard brims from the 80s and 90s will turn to mush if they spend even five minutes submerged in warm water. Even modern plastic brims warp if they bounce around a Maytag front-loader. I've spent the last three years evaluating hat cleaning gear. The market is flooded with cheap plastic cages that crack after two uses. You want polycarbonate or heavy-duty ABS plastic.

Dishwasher and Washing Machine Cages

The Cap Buddy and the Ballcap Buddy are two names you'll see everywhere. I tested the original Cap Buddy (around $12-15) in my Bosch 300 Series dishwasher. It held the hat securely on the top rack. However, the clips are a bit stiff. If you have arthritis, you'll struggle to snap it shut. The Ballcap Buddy (about $18) uses a twist-lock mechanism. It's much easier to use. I ran it through a delicate cycle on my LG washing machine at 85°F. The hat came out perfectly shaped. I'll be honest, the twist-lock can get stuck if detergent builds up in the threads. Just rinse it off after every use.

Hand-Washing Brushes and Sponges

Sometimes a machine is too aggressive. If you're dealing with a vintage wool cap, hand-washing is mandatory. I use the Jason Markk Premium Shoe Cleaning Brush for the sweatband. It's technically for shoes, but the soft hog bristles are perfect for agitating sweat stains without fraying cotton stitching. For the main panels, a simple cellulose sponge works best. Don't use stiff nylon brushes. They will pill the cotton and ruin the logo embroidery. I keep a dedicated set of these brushes in my utility sink. They cost about $8-12 each and last for years if you rinse them out.

Hat Forms and Shapers for Drying

Drying is where most mistakes happen. You can't just leave a wet hat on a counter. It will dry with weird creases. I use the Hat Jack by Perfect Curve. It costs about $20-25. You insert it into the wet hat and expand it to maintain the exact circumference. I've left hats on these forms for 48 hours in a climate-controlled room (68°F). They dry perfectly round. This isn't the cheapest option, but it saves $40 fitted caps from shrinking. If you're on a budget, a cheap plastic bowl from the dollar store works in a pinch. Just make sure the bowl diameter matches your head size.

Deodorizers and Sanitizing Sprays

Sometimes a hat isn't visibly dirty, but it smells like a locker room. If you wore your cap to a tailgate and it reeks of stale beer and smoke, you don't need a full wash. I use the FunkAway Sports Deodorizer. It costs about $10 for a 16oz bottle. I spray the inner sweatband heavily and let it sit for 15 minutes. The enzyme formula actually eats the odor-causing bacteria. Don't just mask the smell with Febreze. That just mixes perfume with sweat and creates a worse stench. For heavy smoke smells, I put the hat in a sealed plastic bin with an ozone generator for 20 minutes. It completely neutralizes the odor without getting the fabric wet.

Washing Machine Cage	Ballcap Buddy	$16 - $20	Snapbacks and dad hats

Practical Steps or Recommendations

Here is my exact routine. I've refined this process after cleaning over 200 hats for friends and local streetwear collectors. Follow these steps to get professional results at home.

Step 1: Pre-treat the Sweatband

The sweatband holds the most oils and dead skin. I spray the inner band with a mixture of white vinegar and water (50/50 ratio). Let it sit for exactly 10 minutes. This breaks down the sebum. After 10 minutes, I take my Jason Markk brush and gently scrub the band in circular motions. You'll see the yellow stains start to lift. If you have kids who track mud everywhere and grab your hats with dirty hands, pre-treating is non-negotiable. Wipe away the excess moisture with a microfiber cloth before moving to the next step. I'll be honest, this takes elbow grease if the stains are old.

Step 2: Secure the Hat in the Cage

Open your washing cage and place the hat inside. Make sure the brim sits flat against the bottom curve of the cage. Snap or twist the top half shut. Give it a gentle shake. If the hat rattles around, it's not secure enough. A loose hat will bang against the plastic and damage the embroidery. I always double-check the locking mechanism before putting it in the machine. A broken clip mid-cycle is a nightmare to fish out of the drain filter.

Step 3: Run the Correct Cycle

Place the cage on the top rack of your dishwasher. Never use the bottom rack. The heating element sits at the bottom and reaches temperatures over 150°F. That heat will melt your plastic cage and warp your hat's brim. Use a gentle cycle with a mild, bleach-free detergent. I use Seventh Generation Free & Clear. Run the wash, but cancel the heated dry cycle. You want the hat to air dry. If you're using a washing machine, put the cage in a mesh laundry bag for extra protection. Run a cold water delicate cycle.

Step 4: Shape and Air Dry

Remove the hat from the cage immediately after the cycle finishes. Insert your Hat Jack or plastic bowl form. Expand it until the hat feels taut but not stretched. Place the hat in a well-ventilated area away from direct sunlight. Sunlight will fade the dye while it's wet. I usually set mine near a ceiling fan. It takes about 24 to 36 hours to dry completely. Don't wear it while it's damp. Your head will stretch it out of shape and ruin all your hard work.

Common Mistakes

I see people make the same errors constantly. Avoid these pitfalls to keep your collection looking fresh.

Using the Bottom Rack of the Dishwasher

I mentioned this earlier, but it bears repeating. The bottom rack is a death sentence for hat cages. The exposed heating coil will melt the ABS plastic. I learned this the hard way with a $15 cage and a vintage 1996 Chicago Bulls snapback. The plastic fused to the brim. Always use the top rack to keep the hat safely away from the heating element.

Using Bleach or Harsh Detergents

Standard laundry detergents often contain optical brighteners and bleach alternatives. These chemicals strip the dye from cotton and wool. If you wash a navy blue New Era cap with Tide Plus Bleach, it will come out looking purple and patchy. Stick to mild dish soap or specialized sneaker and apparel cleaners. Your hats will thank you.

Skipping the Drying Form

Leaving a wet hat to dry on its own is a rookie mistake. As the cotton fibers dry, they contract. The hat will shrink by at least half a size. The crown will also collapse and look deflated. Always use a form to hold the structure while the moisture evaporates. It takes two seconds to insert a Hat Jack.

Submerging Vintage Cardboard Brims

If your hat was made before 1983, it likely has a cardboard brim. Water destroys cardboard. You cannot use a cage or submerge these hats. Spot clean the crown with a damp cloth and use a soft eraser for the brim. I've seen people ruin priceless vintage pieces by tossing them in a Cap Buddy. Check the brim flexibility before washing. If it bends easily and feels thick, it's probably cardboard.

FAQ

Can I use a regular laundry bag instead of a cage?

A mesh laundry bag won't protect the hat's structure during the spin cycle. The hat will get crushed and the brim will bend permanently. You need a rigid plastic cage to maintain the shape against the water pressure.

How do I clean the hat cage itself?

I rinse my cages with warm water and a drop of dish soap after every use. Detergent residue builds up in the hinges and locking mechanisms over time. If the plastic gets cloudy, wipe it down with a 50/50 mix of water and white vinegar.

Do I need a special detergent for wool caps?

Wool requires a pH-neutral detergent to prevent the fibers from felting and shrinking. I use Woolite Delicates for any wool or wool-blend baseball caps. Standard alkaline detergents will ruin the texture and cause the material to pucker.

Will the dishwasher melt the plastic brim?

Modern plastic brims can handle warm water up to 110°F without warping. The danger isn't the water temperature, but the dishwasher's internal heating element used for drying. Always cancel the heated dry cycle to keep the brim perfectly flat.
