How to Clean a New Era Cap: Spot Cleaning, Hand Washing, Visor Shaping and Storage

A New Era cap can look worn out long before it actually is. Sweat lines on the band, dust on the crown and a visor that has started to bend the wrong way are the usual culprits, and most of them can be fixed at home. The catch is that the right method depends on two things: the silhouette (a structured 59FIFTY fitted behaves very differently from a soft 9TWENTY) and the fabric. This guide pulls together New Era's own published care advice, from its customer care center and its cap care guide, into one practical routine for cleaning, drying, shaping and storing your caps.

Start with the care label

New Era is clear that there is no single rule for every cap. Its customer care center says that "due to the diversity of fabrics used to create our caps, there is no 'Golden Rule' when it comes to cap care." Its cap care guide adds a first rule that overrides everything else: check the care label inside the cap, and if it gives specific instructions, follow those over any general advice.

Two more checks before you touch a cap with water:

• Is it leather, suede, silk or another designer fabric? New Era says caps with these materials need very special care and should not be exposed to water at all.
• Is the visor cardboard? If the visor feels paper-like or slightly compressible when you squeeze it, the guide says it is a cardboard visor and water should be kept away from it entirely. Most modern caps have plastic visors, but older and vintage caps often do not.

The quick-care chart by silhouette

New Era's guide sorts its caps by structure and material. Here is the summary in plain terms:

The takeaway New Era draws from its own chart: structured fitted caps like the 59FIFTY should be spot cleaned only and never submerged or machine washed, while soft, unstructured caps with plastic visors can handle a more thorough hand wash.

It is worth knowing that New Era's customer care center is more cautious than the chart. Its general advice for cotton, polyester and wool caps is to spot clean with a damp cloth and a mild, color-safe detergent, and it states that its caps are "NOT washer friendly." If you are unsure which category your cap falls into, the safest choice is the one both sources agree on: spot cleaning.

If you are still deciding between these silhouettes for your next purchase, our New Era cap buying guide explains how the 59FIFTY, 9FORTY and other shapes differ in fit.

How to spot clean a cap (the safe default)

Spot cleaning is the method New Era calls required for structured fitted caps such as the 59FIFTY and for any vintage cap with a cardboard visor. The steps from its guide:

1. Dampen a clean cloth with cool water and a small drop of mild detergent.
2. Gently blot or dab the stained area rather than rubbing hard.
3. For stubborn sweat stains, apply a paste of baking soda and water, leave it for about 15 minutes, then dab it away.
4. Wipe the area with a fresh damp cloth to remove soap residue.
5. Let the cap air dry completely before wearing it.

For the sweatband, the customer care center suggests folding the band forward and cleaning it with mild detergent and cool water. Dust on the crown can be lifted with canned air or a vacuum attachment with soft bristles.

One detail that is easy to miss: New Era advises against spot cleaning across color panels. To keep dyes from bleeding, clean one color at a time. Treat spills quickly too, since the guide notes that fresh stains lift far more easily than set-in ones.

New Era sells two small tools for this job. The Cap Brush ($6.99 on neweracap.com when we checked on November 2, 2026) is designed to lift dust, dirt and lint without changing the texture or color of the fabric. The Cap Spot and Stain Eraser ($4.99) is meant for small stains that are not caked in, on most cap fabrics including polyester and wool. New Era suggests testing it on a small section first and brushing off the residue afterward.

How to hand wash a cap

For caps the chart lists as hand-wash safe, usually unstructured or adjustable styles with plastic visors, New Era's guide describes this method:

1. Fill a clean basin or sink with cool to lukewarm water, never hot.
2. Add about a teaspoon of mild liquid detergent.
3. On a multi-color cap, test colorfastness first by dabbing a wet, soapy cloth on a hidden spot inside. If dye transfers, skip the wash and spot clean instead.
4. Submerge the cap, swirl the water gently and let it soak for 10 to 15 minutes.
5. Scrub the sweatband and stains with a soft toothbrush, avoiding pressure on embroidery and patches.
6. Rinse under cool running water until no soap is left. Leftover detergent attracts new dirt.
7. Squeeze water gently from the crown only. Never twist or wring the visor.
8. Pat dry with a lint-free towel.
9. Dry the cap on a round form, an upturned bowl or a balled towel in a shaded, ventilated spot.

Fabric-by-fabric notes

Wool blends need the most care. New Era says to use cool water only, because heat and agitation make wool fibers mat and shrink. Avoid enzyme-based cleaners, which break down the proteins wool is made of, and choose a mild, pH-neutral detergent or a wool wash. Reshape the crown while damp and keep hair dryers away.

Polyester is the most forgiving material. It resists shrinking, handles moisture well and dries quickly in a shaded, ventilated spot.

Cotton can be hand washed in lukewarm water. For sweat stains on the band, New Era suggests the baking soda paste, left for 15 to 20 minutes and then scrubbed with a soft brush. For oil-based stains, dab a little dish soap on the spot before washing. High heat shrinks cotton, so always air dry, and wash dark and light cotton caps separately for the first few washes.

Nylon is common on athletic and outdoor caps. It does not absorb much water, so a quick hand wash in cool water works. Dry it out of direct sunlight, which can make nylon yellow or fade.

When a washing machine is (barely) acceptable

New Era's guide allows a machine only for unstructured cotton or polyester caps with plastic visors, and even then says hand washing keeps the shape longer. If you go ahead, put the cap in a mesh laundry bag or a cap washing frame, use a gentle cycle with cold water and a little mild detergent, skip bleach, take it out as soon as the cycle ends, and air dry it on a form. Structured caps, wool blends and anything with a cardboard visor should never go in the machine.

The mistakes that ruin caps

Across both of its care pages, New Era repeats the same warnings:

• No dryer, iron or steamer on patches. Heat warps visors, shrinks cotton, mats wool and can melt the adhesive on logos and patches. Air dry only to keep the size.
• No bleach on wool blends. It damages wool fibers and causes permanent discoloration.
• No soaking structured fitted caps. Soaking can weaken the internal buckram that holds a 59FIFTY's crown shape.
• No wringing. Twisting the visor can bend or crack it for good.
• No harsh chemicals or dry cleaning.

How to keep a visor flat, or curve it

A flat visor stays flat mostly through storage. New Era recommends keeping the cap on a flat surface or in a carrier, never stacking heavy things on it, and never storing it visor-down. If a flat brim develops a slight warp, the guide suggests leaving it under a few heavy books overnight.

If you prefer a curve, New Era describes four methods. Its own Visor Curve tool ($9.99) clips along the edge of the visor and is secured with an adjustable snapback fastener; the guide says to remove it after about an hour. The other options are a thick rubber band left on overnight or for 24 to 48 hours, a brief steam treatment of 15 to 30 seconds over a kettle before bending the softened visor by hand, and simply rolling the visor between your hands over several days, which New Era says carries the least risk of over-curving. Keep in mind that the steam method involves heat, so it is not one to use near patches or on caps whose label warns against it.

Storage that keeps caps in shape

New Era's storage advice is simple:

• Travel: use a cap carrier so the crown does not get crushed and the visor stays protected. New Era sells 2-pack ($32.99), 6-pack ($37.99) and 24-pack ($59.99) carriers sized for its silhouettes.
• At home: hang caps by the back strap or closure, never by the visor. On a shelf, store them crown-up with the visor facing forward.
• Long term: stuff the crown with acid-free tissue or a clean cloth, keep caps cool, dry and out of direct sunlight, and use breathable cloth bags instead of sealed plastic, which traps humidity and can lead to mildew. For wool caps, New Era suggests a cedar block nearby to deter moths.

How often to clean

New Era Cap Australia's cleaning page suggests washing caps weekly if you wear them every day, or monthly if you wear them up to three times a week, plus an extra clean whenever a cap is dirtier than usual. For structured fitted caps, read "wash" as a careful spot clean.

A final word of caution

New Era also notes that its cleaning suggestions are based on good-faith experience, may not suit every situation, and that it is not responsible for damage from following them. If a cap is rare or valuable, a gentle spot clean is the lowest-risk choice.
