My house has what appears to be a coated stainless steel railing, inside and outside, which is corroding. It's 5 years old (we've owned the house for 1 year). As you can see from the picture, it's worst on the small crossbars but it's appearing on the larger bars as well. I want to stop the corrosion and keep the bars safe as long as possible, or replace them if they're on the way out.

We have a 3 month old who will be pushing on these one day, so safety is priority 1. If the bars will be shot in a year, I would rather replace them now. But, I'm wondering if they can be safely repaired or protected. I've considered spraying them with a rust remover, and then a clear spray paint (specifically for rust, if there is such a thing). I've also wondered if the remover would damage whatever is left of the existing coating, and maybe I'd be better off skipping the rust remover and going straight to the spray paint.

FYI, this is in Colorado, meaning intense sun/UV and some snow.

Advice very appreciated!
