Because you noted that you are a homeowner-hobbyist rather than an industry professional, I would want to start by making sure that when you call something 'corrugated iron' that you are sure that is what it really is.
If you are actually referring to galvanized steel corrugated roofing material, what you are looking at may be 'white rust' (the zinc corroding), not salt stains. You can search this site for other threads about 'white rust', but I don't think there is any way to remove it and restore the galvanized zinc finish; I think you'll need to paint it.

If I were in your situation I would use full strength vinegar ⇦ in bulk on eBay or Amazon [affil link] solution. I would use a spar varnish (outdoor/exterior) to seal the metal. Good luck!
