Table "Salt" (In/Outdoor)

For stains : Treat with a sponge and Marseille soap.

For greasy stains : Spinkle with "Terre de Somiières", leave to act, vacuum and sand lightly with N°150 grit.

For intensive use (restaurants, hotels), a colorless matte polyurethane varnish can be applied (a test on an inconspicuous part of the product is recommended).

This is a varnish that changes color very little :
