If you are practicing regularly, like you should be (at least once a day) be sure to change your guitar strings once a month. You will be amazed at how much of a difference in sound quality a fresh pack of strings will make. You don’t need super expensive strings. When I was starting out, I got by quite happily on my local music store’s house brand of strings that cost about $4 a pack.
String$:  When you're done playing, wipe your strings with a cotton cloth or old T-shirt that's been treated with a small amount of light household oil such as WD-40. This cleans the strings and displaces moisture that can shorten string life. This simple process will extend string life 3 to 4 times compared to untreated strings, saving you money, and giving you more time to spend playing your guitar instead of changing strings.
