    The Ospho I use doesn't leave a discoloration or change the rust to iron phosphate. It dissolves the rust and leaves it clean looking. I have used other products that convert the rust but my Ospho dissolves it leaving shiny metal. A Web search shows that Ospho now has many products so you may be describing one of their other products. Mine is a light blue liquid.

    You may have to polish after the Ospho dissolves the rust depending if it's a deep rust or a surface rust.

    Wait a minute - if it's good stainless, it shouldn't rust ....

    Agreed. But there is light rust on the box and much more on the exhaust pipes.

    Just be sure to try it on a small area first.

    I believe there are grades of stainless that are harder (due to % of carbon steel) that do rust...at least that is what my outboard motor guy said about my prop.

    Hi guys.

    I apologize for not following through.

    I started out old school and started working it by hand with steel wool. Began on the tail pipes and the rust came off pretty easily. Mind you the tail pipes are discolored from heat, but the rust came right off.

    So I just worked the rest of the underside, which is also discolored, and the rust was heavier than the muffler ends, sides and top, the can itself.

    Bottom line I used steel wool on the whole unit so never tried any rust cleaning products. It took a couple hours but the job is done and looks good.
