Leather care for black leather is simple: If you do not abuse your belt then you should not worry about the leather care for black leather belts. I have an original black belt strap that is 16 years old and it has never been re-dyed. If your belt is white or any other bright color, be sure to not let anything come in contact with it that will show up on it. Bright colors will wear much easier and the acrylic dyes used usually show some cracking up close. This is normal. If you use any type of cleaner to try to clean an acrylic dyed strap, you will most likely smear the color of the strap. This includes window cleaner that can be used on the plates. DO NOT let it get on your brighter colored straps, only on the plates.
