Grit Media?
I have some nice ceramic tiles that are heavily incrusted with water
deposits (Metal content- calcium). They are vertical and quite a few
square feet and acid washing is not practical. It was recommended that I
sandblast the deposits. I don't want to damage the tile, so I was
wondering what might be the best medium to blast them with. Any ideas or
cautions?
TIA
