BTW. This is more like basalt, or actually IS a basalt, as opposed to the<br>
American &quot;bluestone&quot; which is more like a quartzic sandstone.<br>

Have a job to do, or maybe not... It has some light colored spots which look<br>
like etching, but the finish is not burned. The floor went in before the<br>
limestone walls. My guess is that it is grout from the walls which went into<br>
the pores of the bluestone. This would make it impossible to scrub off and<br>
pressure washing will probably not do it either. Not sure if it is acid<br>
sensitive, tried to 5x and not much happened. What is this stuff?<br>
