Maintenance wax adds an extra layer of protection to our Beeswax products. When Beeswax products are used in damp or humid environments, such as bathrooms or kitchens, a layer of rust can sometimes develop on their surface. If this occurs, gently rub the surface with wire wool and apply a layer of maintenance wax with a rag or brush. We recommend occasionally re-coating your Beeswax items with a layer of maintenance wax.
