How often should i change my acoustic guitar strings?

If you want an old trick that will stop the sweat while you are playing. Use baby powder. It smells good, won't damage the strings and will slide easy. Don't put on the fingers but rather, in the palm of your hand. It removes the sweat. Wiping the strings is a good thing also. After while, you won't need to do it as often. You are nervous which is why you sweat a little. Do that trick. I had the same problem in my youth...LOL As for changing strings, I change them every week on the electric, and once a month on the acoustic since I play it less often.

More important, switch to coated strings like Elixir. They are impervious to hand chemistry. How often you change your strings depends on how much you play and how much damage you're doing to them. I use Elixir Nanoweb light gauge acoustic strings and I change them every few months. With non-coated regular strings I changed them a lot sooner.

change the strings as often or as little as you want, its down to you as an individual. When you realise the strings are sounding dull and 'not quite right' change them. Don't worry too much about the dirt.

find any coated guitar strings, and it would help to know what kind of guitar you have, so we can reccomend any brands. and for you, change the every 1 and a half months, if you dont get the coated strings.

Between Lester and Left-T, you've got some pretty good answers there. My acoustics are all classical jobs... nylon strings, so chemistry-related wear isn't something I deal with on it. On the electric, I can get away with every two weeks, but I don't play daily. When I DO play daily, I need to change them weekly, but this has more to do with the fact that I 'play hard' on light gauge strings. Cleaning wipes (for guitars) can help remove some of the gunk. Fretboard conditioner might be a good buy for you too... helps clean off some of the gunk, plus protect your neck and fretboard from accumulated body soil. But I'm just chiming in on Lester and Left-T's answers, which are both very good solutions.

Left-T covered most of the bases so I'll just add: be thankful you're not a bassist. Our strings usually go for about $20/pack!

For non-coated strings I would recommend changing the strings once a month, or more frequently if you have several gigs in the month. During my professional years I played the strings through two engagements before changing them--provided the gigs were within a single week. Left-T's suggestion about using baby powder is on target, especially to give your hand the slickness needed to move up and down the fretboard with ease. After playing, take a dry, clean cloth and run it under and on the strings to remove dirt and grime. That action alone will lengthen the playability of strings.

I will give you an anology,parable if you like.The 8 liners are wrong from the start;mercy for their theme never ends up in a solution.It is strict demand that they get their part of the job or "bargain" done attitude which is going to be of any help.Having sympathy or empathy for their messed up course only causes the birth of wrong lineage or a family line that is rusty and thus an obstacle for clear rustless strings that produce good clean music.Yes change the strings when you can't hear the music,it has to be regular depending on if they get negative.I think its like 1 rotten apple spoils the whole basket of them.

Every day if you can afford it, and have the time, But really some people's hand sweat more then others. most of the grim is under the string. I use to take rubbing alcohol , and clean them with that trying to be careful not to get it on the finish, then a clean damp rag, sweat has allot of salt in it, causes corrosion, rust
