1. Satin Finish
The satin finish rubs to a semi-gloss over time according to how it is held by its player. To clean any fingerprints, rub the finish very lightly with a barely dampened cloth (a cotton T-shirt would do the trick), or rub very lightly with an extra-fine steel wool pad to remove dirt or stains.
*NOTE: The harder and longer you rub, the more your satin finish will buff up.
2. Gloss Finish
Many polishes may be appropriate for cleaning our gloss instruments, however you should always test an area first, and we can not guarantee the results of a particular brand. Here at the shop, we've used 3M Imperial Hand Glaze for years, which is available at your local autoparts store. When applied and removed with a clean cotton cloth, the glaze will give a new shine to the finish and remove some light pick scratching. DO NOT use canned air to blow dust from your instrument as the propellant can freeze, which will crack your finish.
