Step by Step Guide to Clean Hats

Step 1: Find the Stains

The first step of cleaning your hat with borax is to find the stains. Ideally, you will try to catch stains as they happen, but if you have a hat that has built up stains over time, don’t worry. Borax is an excellent cleaner and will be able to remove stains regardless of when they happened. Stains such as sweat, oils, and dirt are common culprits of staining your hat. Typically, these stains are brown and yellow in color. These stains are often found in the band, the lining, and the fabric of the hat itself. If your hat is stained with food or drink, you’ll find the stains on the outside of your hat. Food and drink stains are typically red or blue in color and are found on the exterior of the hat.

Step 2: Mix the Borax and Water Together

Once you’ve found the stains on your hat, you’ll want to mix together a cleaning solution. You’ll want to use a few cups of water combined with a teaspoon of borax for light stains, or a tablespoon of borax for heavy stains. For light stains, you can also use a solution of water and ammonia to help break them up. Always make sure to test the solution on a small patch of the hat before proceeding with the cleaning process. This will ensure that the solution doesn’t damage the material of your hat.

Step 3: Soak the Hat in a Solution of Borax and Water

Once you’ve mixed together a cleaning solution, you’ll want to soak the hat in the solution. Make sure to completely submerge the hat in the solution so that every part of the hat is covered in cleaning solution. You don’t need to wring or squeeze the hat, as this can damage the fabric. If you have a large hat that doesn’t fit in a bucket, you can also use a large bowl or a sink. Try to leave the hat in the solution for at least six hours so that it has enough time to break down the stains. Even longer is better if you have the time.

Step 4: Rinse and Dry Your Hat

After the hat has finished soaking, you’ll want to rinse it thoroughly and then allow it to dry. You can speed up the drying process by placing the hat on a clothesline or a drying rack. You can also put the hat in the dryer on a low setting. While it’s better to air dry your hat, using a dryer is okay for speedier cleaning. Just be sure to keep an eye on the hat as it dries to make sure it doesn’t get too hot.
