Patience and elbow grease will get them back to original form.Thanks. I will be heading out to get some 0000 Steel Wool and shine from homedepot then to start with to get it down to a manageable surface.
As a FYI - the Sheila Shine is a coating you leave on the metal, but it will drip over time down the sides. Keep a rag around the 4 I beam corners and you won’t ruin your floor
