I've been cleaning my 110g tank since it's been stored in my basement since 2013 . I've got it all clean except for the center brace , I've used vinegar , Bar Keep ,scrub pad and wet-dry sandpaper and still can't get the etching off ? Any one come across this problem ? Will treating it like a scratch work ? So Sorry can I get this move to the right location ? Thanks

Given that you tried sanding it most likely your only option is going to be to try and polish it or replace the brace with a new pane of glass.

You need a very fine polish to get glass back to optical clarity. There are special glass compounds that are used for this. I've never done it, but sandpaper isn't a fine enough grit to do it.
