A good cap earns its keep all summer — which means sweat, sunscreen, and sand. Clean it wrong and you'll warp the brim, shrink the crown, or crack the strap. Here's how to do it right, plus the two internet-famous methods you should never use.
The Two Methods That Ruin Caps
Let's clear these first:
- The washing machine. The agitation warps the brim and crushes the crown's structure. A structured cap goes in a six-panel and comes out a lump.
- The dishwasher. The oldest "hack" on the internet and the worst: high heat plus harsh detergent shrinks the fabric, fades the color, and can delaminate the brim entirely.
Caps are shaped objects, not laundry. They get cleaned by hand — and it takes ten minutes.
Routine Care: The 30-Second Habit
Most caps never need a deep clean if you do this: after a sweaty day, wipe the interior sweatband with a damp cloth and let the cap air out overnight — on a rounded surface (a jar, a ball, a rolled towel) so the crown keeps its shape. That's it. Sweat that dries into the band repeatedly is what causes the permanent staining and stiffness people try to fix later.
The Deep Clean, Step by Step
- Spot-test first. Dab a hidden interior spot with your cleaning solution and wait a few minutes. Garment-washed colors — like the washed navy on the Marina Cap — should always be tested.
- Mix cool water + a small amount of mild detergent. Cool, never hot. Hot water is what shrinks and fades cotton.
- Spot-clean with a soft cloth or soft brush. Work the sweatband and any marks on the crown in small circles. Don't soak the whole cap unless it genuinely needs it.
- Rinse with a clean damp cloth. Wipe away detergent residue — leftover soap attracts dirt faster.
- Reshape immediately, then air dry. Set the cap on a rounded form, brim curved the way you wear it, away from direct sun and every heat source. Never tumble dry, never radiator, never hair dryer.
The Leather Strap Rule
The Marina and Founders Cap both close with a real leather strap and brass buckle — a detail worth protecting. Keep the strap out of the water. Soaked leather dries stiff and can crack. If the strap needs attention, wipe it with a barely-damp cloth and let it dry naturally; a tiny amount of leather conditioner once a season keeps it supple.
Care by Cap
| Cap | Watch out for | Care note |
|---|---|---|
| Founders Cap | Structured crown | Always dry on a rounded form to protect the six-panel shape |
| Marina Cap | Distressed brim, washed color | Spot-clean only — the distressing and wash are the character; don't scrub them away |
| Sea Explorer Cap | Soft, unstructured crown | The most forgiving of the three — but still air dry only |
(Choosing between the three? The summer cap comparison and the Founders Cap field guide cover it.)
Sunscreen Stains: The Summer Special
That yellow-orange tint on light caps is sunscreen oxidizing — the Sand-colored Sea Explorer crowd knows it well. Treat it fast: dab (don't rub) with cool water and mild detergent, then rinse. The longer sunscreen sits, the more permanent it becomes. Prevention beats treatment: apply sunscreen, let it absorb, then put the cap on.
When a Cap Is Just... Done
A well-kept cap lasts years, and honestly, cotton caps age well — a little fade and softening is character, not damage. But when one truly retires, don't landfill it. It's the same philosophy as the rest of the line: buy fewer, care for them properly, and keep textiles in use as long as possible.
FAQ: Cap Cleaning
Can I put a baseball cap in the washing machine?
No. The agitation warps the brim and crushes the crown. Hand spot-cleaning with cool water and mild detergent gets the same result without the damage.
How often should I clean my cap?
Wipe the sweatband after heavy-sweat days; deep clean only when it visibly needs it — for most people that's a couple of times a season. Overwashing ages a cap faster than wearing it does.
How do I get the sweat stains out of a cap?
Cool water, mild detergent, soft brush, small circles on the sweatband — then rinse with a damp cloth and air dry on a rounded form. For set-in stains, repeat rather than scrubbing harder.
