Leather is extremely durable and will last you through the ages if you take care of it. Good quality leather resists staining and any dirt or stains can be easily wiped off. However, you can give your leather some extra love by keeping it out of the sun, storing it in a dry place and applying coconout oil to soften it.
Did you know that cotton clothes actually can be washed, dried and heated several times without any notable marks? But instead of bleaching it, you can easily use lemon juice for stains and vinegar for bad smell. This both benefits your clothes and the environment.
