Although leather is a complex material, caring for it doesn’t have to be. If you take the time to educate yourself on leather jackets maintenance and adhere to these best practices, your jacket will remain supple and appealing with only the occasional treatment.
Create water-resistant leather
There are various products marketed as “leather protectors” or “leather waterproofing,” but before you buy, carefully read the label. Your leather’s beauty and gloss should be preserved with a silicone polymer or an acrylic copolymer spray. Although more protective, grease- or wax-based solutions shouldn’t be used on jackets because they could affect the color, durability, sheen, and fragrance.  To learn how long a thing retains its water resistance, check the label on the item. The product typically needs to be apply again every few weeks or months.
Even though the treatment promises otherwise, it won’t entirely waterproof the leather jackets, only making it resistant to water damage. Never put leather jackets in the washer or submerge it in water.
Occasionally use leather conditioners
While applying leather conditioner to the leather restores the oil and prevents excessive dryness and cracking, too much oil can clog the pores and alter the colour or durability of the jacket. Leather conditioner should only be used when the jacket begins to feel dry or stiff. The following advice will help you choose a product:
Make sure the label is appropriate for the type of leather by checking it. (This is crucial for jackets make of suede or nubuck.)
The leather or leather jackets may become darker if you use pure animal oils, such as neatsfoot oil, mink oil, or other natural animal oils.
Despite the fact that they may be less expensive options with less color change, products including wax or silicone might dry out the leather. Never use anything with mineral oil or petroleum because they can seriously harm your body. You should also stay away from “saddle soap,” at least on untreated leather without a covering that is water-resistant.
On rare occasions, polish jackets made of smooth leather
While adding a gloss to your men leather jackets, leather polish runs the risk of drying out, discoloring, or clogging the leather’s surface. Use this only for exceptional occasions, and try any new products on a secret location first. Use a towel to buff the surface until it becomes glossy.
Avoid polishing suede or other types of leather with a fuzzy, soft feel. Suede cannot be made glossy without obliterating this texture completely.
Use a moist towel to wipe away salt stains
Leather can develop white salt deposits in wet winter weather. To prevent dry patches and cracks, promptly wipe the salt off with a moist towel. Apply conditioner to the troublesome region after letting the leather dry naturally. So in this way you can easily clean your bomber jackets, biker jackets, coat and men leather jackets.
Air-dry wet leather
Hang your jacket evenly on a hanger to dry at room temperature if it gets wet. Remove items from the pockets to prevent the damp leather from being stretch. And keep it away from direct heat sources like radiators or air conditioning units. If the leather had become completely wet, apply conditioner after drying.
Find out how to get rid of wrinkles. Minor wrinkles should be avoid and remove by hanging the garment. It is advise to take the jacket to a specialize leather cleaning if significant wrinkles disturb you. Alternately, drape a cloth over the leather and quickly iron the cloth on the lowest setting (commonly referred to as “rayon”).
So These are the best guidance for leather jackets maintenance.
