Mine had NO visible rust under and no soft spots inside but when I took all of my flooring up I found big rust stains, some were from windows leaking and didn't show on anywhere else and some were unexplainable but they were there.
If you don't send your effort now then all your effort will be spent later tearing apart your finished whatever to fix a soft spot that wasn't there 5-years ago.
Clean it out, put eyes on and clean/fix/repair your foundation and then build or you can ignore it and keep in your head that it is not if but when.
Your structure is everything.
I am building to last so I got rid of everything and started with a clean slate. I know exactly what is under my feet, on my sides and over my head and if I had any question or reserve about what I was thinking of doing it didn't happen until I had a solution that I could do and never question again.
Good luck and HAPPY DECISIONS.
