<div><br></div><div>First if it a true quartzite it should not etch..Especially if it is honed.. So I would approach it this way.</div><div><br></div><div>1, Try polishing the etch out with a standard marble polishing powder</div>
<div>2, If this doesn&#39;t work than try starting with a 400 grit diamond and bring it up till you achieve the hone</div><div>3, If its true quartzite than treat it like granite</div><div><br></div><div><br></div>
