Fingerboard/bridge For all our models you can maintain the fingerboard by applying lemon oil or linseed oil. Body The satin finish has a very thin layer of varnish, for this type of guitar, we recommend that you avoid an abrasive polish, certain products are specifically made for these finishes, otherwise you can make do with a light cleaning product. For a guitar with a glossy varnish, you can maintain the body of your guitar with a classic polish/cleaner, such as Dunlop 65, there are many equivalent products made by GHS, Music Nomad, Armonics... Whatever the finish, be sure to use a clean micro fiber cloth to avoid scratching your instrument.
