No bleach, no baking soda: a simple method recommended by professionals to wash caps without damaging them.

Today, caps are part of the everyday closet. They are used both for protection from the sun and as an addition to clothing. However, with frequent use, sweat, grease and dirt can accumulate on them. This will force you to wash the caps, which can compromise their integrity. Whether it’s your favorite rusty cap or a shiny new one.

And in this sense, a ruined cap not only loses aesthetic value, but can also become a breeding ground for bacteria. Therefore, to keep them clean and properly maintained, you need to know certain details beyond traditional washing. Below we will detail the most common mistakes and the most effective methods depending on the type of cap.

How to determine the material of the cap before washing it

Before washing the cap, it is recommended to check the inner label. This step will determine which cleaning method should be used. Some materials can withstand water and detergents without problems, while others require more gentle care.

The most common types of materials are:

• Cotton: durable but prone to shrinkage when dried at high temperatures.
• Polyester: resistant to mechanical washing. Retains its shape well.
• Lana: delicate. Unacceptable hot water and aggressive detergents.
• Visor with cardboard: often found in older models. It should not be too wet to avoid deformation.

When and how to properly wash caps

The frequency of washing caps depends on the intensity of their use. With daily use or during physical activity, the recommended interval is once a month. For occasional use, the procedure can be done every two to three months.

Here are some precautions to take beforehand:

• Identify localized spots and pre-treat them.
• Test the effect of the product on an inconspicuous area.

With this in mind, there are two basic ways to wash caps: by hand and in the washing machine. Not all types are suitable for both methods. After completing the procedure, it is best to store them in a cool, ventilated place.

What does hand washing a cap look like?

1. Fill a basin with cold water.
2. Add a detergent without chlorine.
3. Soak the cap for 10-15 minutes.
4. Gently scrub with a soft brush.
5. Rinse with cold water.
6. Remove excess water with a towel without twisting.

How to dry caps without deforming them

The main recommendations:

• Do not use a dryer.
• Put a towel inside the cap to keep its shape.
• Allow to dry on a flat surface, away from direct sunlight.
