How to Clean a Golf Hat Without Wrecking It
By the B&C Golf team · Updated July 2026
Sweat, sunscreen, and course dust all end up in your hat. The good news: cleaning a golf hat is easy, and doing it by hand keeps the brim and shape intact. Here's the safe way.
The short version
Spot clean with a soft brush, mild detergent, and cold water, rinse, then air dry on something that holds the hat's shape. Skip the dryer, and be careful with the washing machine.
What you'll need
- A few drops of mild detergent or dish soap
- Cold or lukewarm water
- A soft brush or old toothbrush
- A clean cloth or towel
How to clean a golf hat by hand
- Mix a little detergent into cold water.
- Dip the brush and gently work the sweatband and any stained spots. Don't scrub hard - let the soap do the work.
- Wipe the panels with a damp cloth. For a deeper clean you can submerge a sturdy hat for a few minutes, but go gentle on light colours and printed logos.
- Rinse with clean cold water until no suds remain.
- Press - don't wring - with a towel to pull out excess water.
What not to do
- Skip the dryer. Heat warps the brim and shrinks the band.
- Be wary of the washing machine. It can bend the brim and knock the crown out of shape. If you must, use a cap cage, cold water, and a gentle cycle.
- Skip the dishwasher. Despite the old tip, the heat and drying cycle can warp the brim and fade colour.
- No bleach or hot water, especially on coloured or logo hats.
Sweat stains and odour
For salty sweat lines, work a little extra detergent into the sweatband before rinsing. For smell, a short soak in cold water with a splash of white vinegar, then a normal rinse, clears it without harsh chemicals.
Drying and keeping the shape
Air dry away from direct heat. Set the hat over something round - a balled-up towel, a container, or a hat form - so the crown keeps its shape while it dries. Never dry a structured cap flat.
Light colours and rope hats
Cream and tan hats show marks faster, so a quick wipe every few rounds keeps them sharp. The same gentle approach works for a rope hat - just don't soak the rope detail for long. Keeping a hat clean also helps it hold its shape and fit the way it should.
Frequently asked questions
How do you clean a golf hat?
Spot clean with a soft brush, mild detergent, and cold water, then rinse and air dry on something that holds the hat's shape. Hand washing is safest for the brim and structure.
Can you put a golf hat in the washing machine?
It's risky. A machine can bend the brim and misshape the crown. If you must, use a cap cage, cold water, a gentle cycle, and air dry afterward - but hand washing is safer.
Can you put a golf hat in the dishwasher?
Better not to. The heat and drying cycle can warp the brim and fade colours. Cold hand washing gives you the same clean without the risk.
