I am in Chengdu, and the weather is humid. How to maintain the guitar, especially the strings, are a little rusty.

Hello, if there is rust, I suggest you change a set of strings, because rust will affect the timbre. When not in use, you can put the strings in the piano bag and use soft toilet paper, so that they won't rust. I also like guitar very much. I bought one for 30 thousand yuan, but I didn't know what to do at first. It was covered with dust and rust. Then a teacher told me.
