On my electric and acoustic steel string guitars I always wipe down the strings after playing. I use a rag and lightly pinching each string individually I run the rag up and down the sting once or twice. I started doing this over 20 years ago and found it quadrupled my string life. However, Argentine strings seem to be different and it doesn't seem like this works as well, in fact sometimes it seems to accelerate the aging process. What do you folks do?
