How to Clean a Leather Cap 
There are a number of methods available to clean your leather cap. If you have an oil or grease stain on the hat, you can use Marseille soap to remove the stain. Alternatively, you can try using trichloroethylene, a common cleaning agent for pullovers and dry cleaning. If the stain is larger, you can use specialised cleaning products.
Keeping your hat clean
Keeping your leather cap clean is not hard if you keep it in a safe place and use the right products. Dust and sweat can easily be removed by wiping it off with a soft cloth. You can also use baby wipes to remove stains. For tougher stains, you can use a stain remover, such as baby powder or cornstarch. Repeat this process until the stain disappears.
While you can use the magic eraser to remove stubborn stains, it won’t be good for your leather cap. These erasers can strip the fabric of the waterproof coating, making it not suitable for everyday wear and tear. You need to keep in mind that different materials need different care. While some will respond well to magic erasers, others will get permanently stained or damaged. However, common sense can help you avoid some of the worst mistakes.
After cleaning your leather cap, store it in a cool, dry place and avoid exposure to direct sunlight or moisture. It is also best to use a garment bag that is made of cloth. Never put your leather cap in plastic bags because it can cause mildew and yellowing of the leather.
Using leather protectors
If you have a leather cap, you’ll need to clean it regularly with leather protector products. These are available in liquid or spray-on form and can help repel water and prevent stains. Using one once a year is essential to keep your hat looking as good as the day you bought it. Depending on the climate, you may need to repeat the process more often.
Leather protectors protect the leather against water, snow, and dirt. They also help minimize creases. You’ll need to apply these protectors more often if you wear your hat outside in harsh conditions. Always remember to follow the instructions on the label to get the best results.
The best way to protect your leather hat is to keep it away from oil and makeup. You can also use a leather cleanser from a department store or local shoe shop. The cleaner will replenish the protective layer. Leather protector sprays can also be purchased from the same stores as the leather cleanser. You can also apply these to a wet leather hat and let it dry naturally.
Avoiding putting badges, tapes, pins on your hat
While badges, tapes and pins can look great on some hats, it’s a bad idea to put them on your leather cap. They will mar the finish of your hat and can cause wear and tear. It’s best to avoid embellishing your leather cap at all. If you must add a label or badge, consider getting a professional to sew them on. Improper stitching will leave ugly holes.
Avoiding cleaning a leather hat that has mildew
Leather is highly susceptible to mildew and mold. These fungi thrive in warm, moist climates, and can cause permanent damage to the surface of the leather. In order to prevent this from happening, you should dry the leather properly. When you do clean leather, make sure to only use water that is non-metallic.
First, dry the hat in a dry location away from moisture. Avoid using plastic bags as they trap moisture and promote mildew. Instead, use a hatbox or cloth garment bag. Avoid using plastic bags as they promote mold growth and can lead to spots.
Leather hats are not very easy to clean. You should follow the instructions of the manufacturer carefully. When cleaning a leather hat, make sure to keep it away from high heat and moisture. After cleaning it, make sure to condition the leather properly by using a leather conditioner.
