[TowerTalk] Removing concrete from the galvanized steel legs

[Jim Rhodes]

I would use a small, soft hammer to crush any thicker places.  Not trying
to knock it off, just crush it in place.  Using the minimum of force
needed.  It may take a while if there is a thicker amount. Then use a brass
brush in a drill for stubborn stuff left, again minimal pressure as you are
trying to save the galvanizing.   Vinegar soaked rag to clean off any scum
left, followed by a good rinse to remove any left over vinegar.
