In the humid weather in the south, guitar strings easily rust after a few days. Is there any effective way to prevent the strings from rusting?

1, wash your hands before playing the piano, and then play when you are dry. It's better to put a piano box or bag after playing. When you feel particularly wet, you can put a bag of desiccant in it. You can spray rope oil on the rope. You can measure this yourself. Oil is quite expensive, about 100, and the string is almost a few dollars. 4. play more.
