Introduction
Nippers easily oxidize, which leads to rust when they are used for a long time. Rusty nippers are harmful to people's health so they should be cleaned prior to use. Instead of throwing the nippers away, you can remove the rust with a simple mixture of baking soda and vinegar. If your Nipper D-108 has become rusty, follow this guide and they will be clean and ready to use.
