Just wanted to post about acid washed marble since I couldn't find much info about it when I was making my marble decision. I got Carrara marble and the place that fabricated recommends an acid wash finish that basically pre etches the surface. Then they put four coats of sealer on it. I have had it for about two months and so far it has been great. No etches or staining yet. It is not shiny since the acid hones it and it has a different type of feel than just regular honed marble. I really like the feel of it and everyone that comes over can't stop touching it. Hope this helps anyone that might be thinking about marble.
