Back when I was first learning to play, I trashed strings after a single jam session. Gunk build up, they would rust, etc. It was so bad that I gave up playing guitar for a long time...10 years. My hands sweat a lot AND I have acidic sweat. So I know where you are coming from.
When I did take up playing again, I tried fast fret and finger ease. They didn't really help. I tried different types of strings...including stainless steel! All they did was wear down my frets - they were horrible though they did last longer. For years, I switched to heavier guage strings - 11s. That helped, but wasn't perfect.
Today, I am back to using nickel wound 10's on my guitars, Daddario XLs and more recently Earnie Ball. I change my strings faithfully every month - which means a good 15-20 hours of solid playing on them. The way I get a full month out of them. What I do is after EVERY time I play, I wipe the strings down with string cleaner/lubricant that came with my Gibson guitar maintenance kit. I wet a small rag and grab each string and wipe up and down 3 or 4 times - tops and bottoms. My strings still tarnish quickly, but they sound fine and tune well right up to the end. I'm finding I perfer my strings once they've tarnished a bit because I can grab them easier for bends.
