DR Stringlife? is not just another string cleaner.? It cleans the strings, takes off finger oil and acids and leaves a protection layer that keeps the strings from interacting with oxygen and sweat. Apply to new strings for longer lasting tone and feel. For best life-extending results, clean and protect your strings after playing. Apply to old strings for a clean feel and improved sound. With its molecular bonding capabilities, Stringlife™ bonds to strings by causing the positive charge of electrons in your strings to attract to the negative charged polymer and forms a barrier between strings and the elements (like acid, dirt and grime) that steal their life. Treat your strings for longer life - with DR Stringlife.
