Machine washing performance wear hats?

I have a large tub sink in my laundry room so I soak mine in oxyclean detergent and hot water and then rinse.. It get the job done... If it's really bad I use Dawn and a scrub brush ..

Dishwasher is the best on this. Doesn’t ever submerge them and heat dries them some.

If I'm at home or in the hotel showering after a round, I'll take my hat or visor in there with me and use soap and a washcloth to wash the hat too. When finished, I leave it hanging in the shower to drip dry.

Great hats.

There's a spray called "Hat Saver". When I buy new hats, i basically drown it in that.

Spray and wash and the top rack of the dishwasher. On most dishwashers there is a top rack only setting. Take them out a place in front of a box fan. Done

I’ve been using the dawn platinum plus power wash spray and it’s worked great. I use hot water to soak the hat then spray it with the dawn and let it sit for an hour or so then rinse it off.

I sweat a lot in general and clean all my hats this way. Performance material hats are even easier because the bill is usually made of a material that doesn't get destroyed if it gets too wet. Warm water and laundry detergent in a bowl. I have a small brush that was made for cleaning shoes I believe. I soak the hat in the water trying not to get the bill too wet if it isn't made for it. Then lightly brush it. I can typically get hats looking pretty new without much effort at all. About 5 minutes worth of work and I don't have to worry about things getting smashed/creased in the washing machine or run an entire dishwasher cycle.
