Repairing marred limestone
Our longtime cleaning lady created a 6" drip mark today on our brand new limestone backsplash -- with what, we don't know yet. GRRRRR. Hubby suggests sanding (grinding) and re-sealing. Would that work? Seems like it would, but I wanted to get some opinions first.
Here's a link to a picture.
Thanks in advance.
