For a gentle clean, wash your hat by hand. This is best for delicate fabrics like cotton, wool, and synthetics. Follow these simple steps to keep your hat looking great.

To wash your hat by hand, you will need only a few basic items:

  1. Some lukewarm water
  2. A mild detergent
  3. A basin or sink
  4. A soft-bristle brush or a toothbrush
  5. A clean towel 
Well done! You have collected all the items we will use for our mission. You are now selected for the next process. Follow these steps!

Step 1: Preparation for Hand Washing

First, remove any coarse stains from the hat with a soft-bristle brush and a gentle touch. Then fill a basin or sink with lukewarm water, as it is effective in removing stains. And remember, check your hat's label first. Make sure its material is good for warm water. For example, wash wool hats with cool water to prevent shrinking.

Step 2: Prepping for Spot Cleaning

Now, take your mild detergent and add a small amount of it to the lukewarm water in the basin or sink. Mix the water to ensure thorough mixing of the detergent.

Now do not start making foam bubbles..!! Instead, take your bristle-brush or toothbrush and rub and scrub the cap wherever you see a stain. When you have everything scrubbed up, take the hat and submerge it underneath the water.

When you do that, keep using your bristle-brush or toothbrush. Work back and forth to get all the detergent and soap out. After scrubbing, rinse it with clean water to remove any soap or foam. If you do not clean the detergent, the foam will remain in your cap, so wash the cap.

One quick disclaimer: Before you put your hat in the water, check the bill. Most hats are plastic, not cardboard. If it is cardboard, it will get soggy.

Step 3: Air-Dry Your Hat

After washing, let your hat air dry. Remember, do not use a dryer because it will ruin your hat. You can put a rolled towel or newspaper under it to keep its shape normal. This way, the brim will not get bent.

Congratulations..!! You did it. You have won the new brand hat.
