    Muratic Acid is just as the name implies an Acid.  It is caustic, but I have used it before in a diluted concentration to remove gum and stains from sidewalks.  I would think that as long as you diluted it say start with 10% solution it would be safe.  If it appears not to be working, try a stronger concentration.  But be careful not to damage the floor material.

    Hope this helps some!
