Thread: rust on stainless steel rail and ladder

    rust on stainless steel rail and ladder

    I placed my stairs and ladder in my shed along with my 3 inch tabs. It appears the tablets were a bit wet. The stairs and ladders had quite a bit of rust on them. They were perfect when I stored them. I can polish them with Noxon and they will look ok but I can still see some pitting. They look ok to me but am concerned with rust getting into the water and causing water problems down the road. Is it time for new stairs and ladder or will I be ok. On a side note what may have caused this?? Pool is vinyl, no heater 18 X 36 inground.

    You should never store trichlor tabs or any solid form of chlorine in a location that has metal parts (garage, shed with lawn equipment in it, etc). Solid forms of chlorine emit chlorine gas even when completely dry and none of the containers are sealed (they are designed to breathe to avoid vapor build up). The chlorine vapors will oxidize and corrode anything metallic.

    If you can polish the steel back to bright & shiny that would be good. A good way to remove rust stains is with Bar-Keeper's Friend cleanser. It's a mixture of mild abrasives and oxalic acid. Oxalic acid is very good at dissolving rust but leaving a clean metal surface behind. Unfortunately, if the pitting is severe, then you'll need to be careful in managing your pool water pH to make sure it stays in a balanced range (not less than 7.5 and definitely no lower than 7.2) to avoid further rusting.
