1. Ordinary holster:
1). You can wipe it gently with cotton cloth. If it is dirt that is difficult to clean, such as glue, it can be cleaned with alcohol.
2). You can choose a professional cleaner.
3). Be careful not to wash with water, because most leather is breathable. If water is used to imitate leather, it is easy to cause water to enter the holster.
2. Smart holster:
Samsung smart holster has many functions. I suggest you be extra careful when wiping. You can gently wipe the upper and lower sides of the holster with a semi-wet cotton cloth, instead of wiping the edge of the holster.
