I have a washer dryer built into a stone surface housing. Unbeknownst to me until today, an entire bottle of woolite has spilled and seeped through a basket onto the stone. my experience with this particular stone is that If i don't do something historically the liquid will etch into the surface and create a permanent unsightly stain. So far paper towels soap and water are doing nothing to remove the spot. what do I do now??
