Trick Carnauba Piano Care Kit contains Piano Polish (4 fl. oz.) and polishing cloth. Trick Piano Polish is nonabrasive and antistatic, a perfect product for keeping your piano looking like new. It works on any instrument finish and won"t scratch, streak, or swirl as it removes fingerprints and residues from smoke, dust, and sweat. The 12" x 12" microfiber polishing cloth will not scratch even the most delicate finishes and its 100,000 microfiber strands per square inch grab, lift, and hold grime like a magnet. The polishing cloth can be laundered and reused.
