Hat Sweat

I put mine in the dishwasher, but I tend to stay away from white hats so I'm not sure how to get discoloration. Maybe dishwasher and then hand wash with bleach?

I just toss 'em in the wash machine.  No problems with shrinking.

 

Not sure you'll ever get out real bad yellowing though.....

Yeah, I have the plastic things. I've never had any shrink noticeably.

 

I do the same, but it does wear and fade the color of the hat pretty bad.

I have tons of hats, and wear all white hats often (see avatar). I toss mine in the washing machine with Tide, Bleach and OxyClean (RIP Billy Mays) on hot water setting. They always come out pretty clean. My fitted hats do seem to shrink slightly, but they are usually a little too big to begin with. They are the flex fit so a slight shrinking (on hats) is not an issue.

I use the plastic things, but I sweat pretty bad so there is always a slight discoloration no matter what the color and the damn hats never keep their shape fully after one wash.

 

I am only buying Loudmouth painters caps now because they do not really need to keep their form.

I have a dark navy blue hat that I destroyed with my mutant sweat on the very first day I wore it. Parts of it turned brown LOL, sucks because it was/is a great hat. Tried the dishwasher and regular washing machine, still looks disgusting.

I have the White Titleist Mesh hats. I put mine in the dishwasher after a few rounds. They come out looking brand new. My nephew couldnt tell the old freshly washed from the new one I had just bought him. The other colors will fade so white is the best for washing.

One of these in the dishwasher is what I use.  I've washed all color of hats.

In the summer, I take the offending hat into the shower with me and try to get the sweat out before it dries in and sets. This gets some more life out of them. Once they get yellowed, I have never seen a cure so I only wear white hats in the winter. 

I do this as well.  For my white hats, I just scrub it with body wash and rinse.  I let it hang dry.  If you rinse the hat right away, the yellowing won't happen as much.  I've done this with Nike and Mizuno white hats that are moisture wicking (I sweat a lot).  I also rinse my Red Sox hat and have had no issues and it is part wool.  Love that hat.  It has been with me on five continents!  i just need Africa and Antarctica to complete the set.

I just throw mine in the washing machine.  Just make sure that you let them air dry or else they will shrink.

You dishwasher guys...do you put them in there by themselves, or do you throw them in with the dirty dishes and some detergent?

No dirty dishes but do add detergent.  Place them in the top rack

This.
