The ideal way to increase the life of your strings is to keep them clean and dry. Not only does this help prevent corrosion, but it also helps prevent fraying and breaking. If you are playing the guitar that has open coils or has been heavily played, you should consider replacing the strings with fresh ones at least once per month (more often if needed).
It will not only help your instrument sound better, but it will also help ensure that your guitar will last as long as possible. Here are some tips to help you make sure your guitar strings get the most out of their lives:
Do not overtighten
Do not under-tighten
Keep them clean and dry
Please do not leave them on too long
