    Stem tube. How to remove stain?

    Hi. I have a white colored bicycle stem. I had a Cateye wireless sensor that i removed from it and now it's stained yellow. I tried using WD40 and simple green but nothing works. What should I try using to remove the stains from the aluminum? Thanks

    My guess is that the stem is painted white and clear coated. The stain is probably in the clear coat. In other words . . . it ain't comin' out. Save yourself the hassle and buy a new one if if bothers you or just deal with it.

    Would it be possible to sand it down and paint it? I have Rust Oleum metal spay paint and clear coat paint. Not sure how well it would turn out.

    Try using an automotive Clear Coat cleaner/wax like McGuires. A polishing compound might work if the former does not.

    This would be a good place to start if you haven't already.

    You could I suppose, but as you note, it probably wouldn't turn out as well unless you had it professional powder coated. If you went that route, I'd let them handle the stripping.

    Is this like some sort of out of production, vintage area, never to be found again stem? Why not just buy another one?

    Wrap $0.05 cents of white electrical tape around the affected area and keep riding.
    Safe riding,

    Try Micro Mesh on it.

    If the stain bothers you enough to want to do something, spray painting won't satisfy you either. leave it be or buy a new one.

    Try a Magic Eraser. I have no idea what is in those things, but it seems to be magic.

    Thank you for all of the suggestions. You guys are right. It will most likely look like crap when I'm done with it. I'm just going to purchase a new one.
