What's the best way to get the sweat smell out of a New Era baseball hat?

Question

my hat has that nasty vinegar smell.

Answer 1

Have you tried throwing it into a clothes washing machine with a few other things (towels, shirts, etc.) and running the load through the full cycle?  When the load is finished, just put the clothes in a dryer but keep out the hat.  

Shape the hat by hand.  As it dries (I put mine over a coffee can or a round top plastic container), I check it once in awhile and, when it is almost dry, I spray it liberally with spray on clothes starch inside and out.  Continue to shape and let it dry completely.

There you go, a nice clean hat, in excellent condition, that doesn't smell like a tennis shoe.  If you shaped it several times while drying, it looks as good as new and smells that way too.

Answer 2

you can buy a plastic holder thing that is the shape of a hat, put your hat in it and throw it in the dishwasher, by itself of course.  The plastic thing will help it keep its shape.

Answer 3

I take it you have tried washing & airing it out. Most things seem to mask smells. Don't know if this will work as well for hats but I have found that stuffing newspaper inside stinky shoes helps calm those odors. Perhaps it would work you hat.

Answer 4

Have your cat pee on it.  You will no longer notice the sweat smell.
