Bluestone Mike Marsoun 23 Jun 2010 02:34 EDT
Have a job to do, or maybe not... It has some light colored spots which look like etching, but the finish is not burned. The floor went in before the limestone walls. My guess is that it is grout from the walls which went into the pores of the bluestone. This would make it impossible to scrub off and pressure washing will probably not do it either. Not sure if it is acid sensitive, tried to 5x and not much happened. What is this stuff?
