You have acid?
Acid never hurt my strings because I could never figure out which end of the cord to plug into the guitar... or what the guitar was.
Seriously, I go low sodium when I can and never add salt to my food. I never have a problem with my strings, but it is probably just me. I DO use Snake Oil Strings almost exclusively. They last forever and actually become more tuneful after about a week of playing. It is not unusual for them to last months. I use the Vintage, Rock, and Nickel for different guitars. They are well worth a try if you haven't tried them.
