Protect mills from excessive heat and moisture.
Do not place salt or other spices in pepper mill.
Use only dry rock salts (white, pink or blue) 4mm or smaller in salt mill; do not use wet sea salt, even dried.
Use only black, white or mixed peppercorns in pepper mill; not suitable for green or pink peppercorns.
Do not use Peugeot salt mill for grinding damp sea salt, also known as grey salt, (Guérande, Ré, etc.). High moisture content will corrode the mill.
Use a specific Peugeot mechanism for damp salt. Its shape and materials have been designed to resist salt corrosion.

Dry Salt: Rock salt is found in the depths of the earth; it is a fossil salt that has accumulated over geological eras with the evaporation of the seas. Rock salt contains iron and potassium.
Wet Sea Salt: The wet sea salt (as Guérande salt, Noirmoutier salt) is characterized by a consistency and a high humidity that do not allow grinding with a conventional salt mill. This salt is rich in magnesium and trace elements.
