String Corrosion and Prevention
All metal strings are susceptible to oxidation and corrosion. Wound strings commonly use metals such as brass or bronze in their winding. These two metals are very vulnerable to corrosion. The sebaceous gland in the player's skin produces oils that can be acidic. The oils, salts, and moisture from the player's fingers are the largest source of corrosion. The composition of the oil and the oxygen in the air also helps to oxidize and corrode the strings. In steel strings the oxygen reacts with the tin in the steel and it creates the rust. As a result, the string loses its brilliance over time. Water, another by-product of oxidation, increases the potential acid corrosion in oils. Wound strings such as bronze acoustic strings, are very difficult to keep fresh sounding due to the lack of corrosion resistance. To help solve the corrosion problem strings are either metal plated or polymer coated. The polymer coating is claimed to reduce finger squeak and fret wear, and has better tuning capability. Some companies sell lubricating oils that slow down the oxidation process, increasing the string's life-span. These special lubricating oils are applied to the strings as a barrier to the air, to help slow the oxidation process.

Famous quotes containing the words string and/or prevention:
“The Indian remarked as before, “Must have hard wood to cook moose-meat,” as if that were a maxim, and proceeded to get it. My companion cooked some in California fashion, winding a long string of the meat round a stick and slowly turning it in his hand before the fire. It was very good. But the Indian, not approving of the mode, or because he was not allowed to cook it his own way, would not taste it.”
—Henry David Thoreau (1817–1862)
“... if this world were anything near what it should be there would be no more need of a Book Week than there would be a of a Society for the Prevention of Cruelty to Children.”
—Dorothy Parker (1893–1967)
