Rinse off solution thoroughly and let dry. It is the phosphoric acid in the water softener cleaner that removes the rust. A guy can also use rust cleaners and surface etchers sold at auto body suppliers. I have and there is little difference except in my wallet.
I don't see how a conventional 1/4" or larger bolt is going to break from rust-through in just a few years. Even snow plow equipment or offshore steel that is continually exposed doesn't fail like that. There are other forces at work in that situation.
Painting the underside is a good deterrent to rust. I may do that to my 47 yr old trailer since the frame is covered with surface rust. It is a lot of work and has little improvement with low risk to continue with what I have.
