[TowerTalk] Removing concrete from the galvanized steel legs

[Steve, NR4M]

Muriatic acid, with gloves, using a rag.  It will make very short work of the Portland cement in the concrete.   It’s the stuff that is used to etch concrete floors in preparation for painting them with paints, like a two part epoxy. Just was it well when your done.  ( Rub some baking soda on tha area to see if it’s been sufficiently neutralized )
