how to get sweat stains out of hats

I think many of you can understand that a lot of dudes have a favorite baseball hat, and sometime even more than one. I don’t happen to be a baseball-cap-wearin’ female, but they exist.

Whether you’re a male or a female, I find the love of a baseball hat to be infinite and unwavering, at least amongst people I know. And in our Georgia weather, a hat can easily have a short shelf life based on the amount of time you a) sweat; b) hang out in the sun or c) both.

I’m setting the stage for you, my friends.

How to Get Sweat Stains Out of Hats

It all started a few months ago when Steve mentioned to me that he was going to have to throw away his favorite hat. Not because it had holes or a tear or anything like that, but because the heat and sweat had caused it to fade really badly, not to mention some weird staining on the brim.

Before throwing his hat in the circular file, he did have the good sense to come to me and ask what he could do. He was wondering if there was any way he could dye the hat – I mean, he’d tried everything else first (dishwasher, enzymes, etc). Washing just didn’t fix the sweat stains, and the fading was obviously permanent.

I got involved and we were able to fix the hat, and I’m so excited to share how we did it. To give you an idea of how it turned out so you can get excited, check out the before and after:

I know . . . it’s pretty much amazing. And now I’m going to tell you how we did it.

Tulip Color Shot Instant Fabric Color in Black

I’d actually seen Tulip Color Shot used for fashion crafts around the interwebs so it was somewhere in the back of my mind . . . but I didn’t make the connection until we were in Michaels on the fashion crafting aisle.

Steve and I were there together and actually had several products in our hands. I love Tulip brand, and I liked the advertised “even coverage” and “dries soft.” No one wants their hat to dry like a piece of cardboard.

So we decided to purchase the Tulip and bring it home, and I’m pleased to tell you that the results were even more amazing that I could have imagined! Here’s how we brought Steve’s favorite hat back to life.

Gather These Supplies

  • Tulip Color Shot – black (or whatever color your hat is)
  • Painter’s tape
  • Craft knife
  • Cover for your work surface

So this is the hat beforehand – which you may think was a gray-blue-ish shade originally. No . . . it was BLACK. This is what sun and sweat do to hats, people!

This hat is either 100% cotton or close – there might be some poly in it (no tag). I recommend washing the hat one more time before starting to get rid of any sweat and dirt. We just let it air dry.

Logo on a hat taped with painter's tape

Steve didn’t want the logo to be covered with paint, so we covered it with painter’s tape. But it wasn’t exactly shaped to the logo, as you can see.

Trim the painter's tape with an X-Acto knife

This is where the craft knife came into play. We trimmed the painter’s tape around the baseball cap logo for an exact fit.

If you do this, please be very careful! You can plunge that craft knife right through the hat and cause a meltdown on the part of the owner, so gently cut away the tape.

This is what is left behind. Then the rest is simple.

Place the hat on a protected surface and, following the instructions on the can, spray the paint. Steve used three light layers of Color Shot, letting dry for several minutes between each.

He then turned the baseball hat over and did the bottom of the bill (not the inside). Remove the tape and let dry for several hours before handling.

It really worked *that* well! Once you learn how to dye a baseball cap, you can try several colors. We were so pleased with the results, though I do have a few notes:

  • As I said, this hat was mostly cotton, but according to the bottle it works on natural and synthetic materials. Despite this, I always recommend doing a test before starting your project. In the case of a hat, you can do a quick blast to the inside where no one will see it before committing.
  • You should not only cover any logos you don’t want painted with painter’s tape, but also any plastic.
  • The paint does dry soft BUT it takes a few wears to get it loosened up. So don’t freak out if your hat is a little stiff right after painting – it will get soft again.
  • The color is permanent, so you should be able to wash it. We haven’t washed the hat yet, but it has stood up to several days of sweating (so it’s gotten really wet) and there’s been no bleeding.

Update May 2021: we originally posted this six years ago and the hat is still going strong! It’s been washed and there hasn’t been any bleeding. Steve actually did this a second time in late 2017, and it looks like its original black.
