Restore Detailer Deep Cleaning Polish is the first step in D'Addario's three-part restoration system, designed for deeper cleaning when routine upkeep isn't enough. Its cream formula cuts through tough grime while polishing out swirl marks and helping remove minor scratches from clear-coated instruments. Safe on all common guitar finishes, Restore is suited to acoustic and electric guitars, basses, banjos, mandolins and ukuleles. For periodic deep-cleaning sessions, the D'Addario Restore Deep Cleaning Cream Polish helps bring a worn-looking finish back to a cleaner, more polished appearance.
