    Default slate table

    We have black slate table top that has some unknown stains. How can we remove the stains?

    Thank you,

    Try experimenting with various poultice remedies. Different poultice remedies work for different types of stains (like oil based or a rust ring from the surface). If its a mineral oxide from the slate like iron rust from the slab or tile itself not much you can do.

    If your slate is sealed makes a difference as to how you'd approach the project. Also if you've got oil or wax on top. If you have tiles not a slab could be the grout or glue. Not usually a good idea to mess with muratic acid on tile top but on a removable slab top sometimes a remedy of last resort especially if mineral/salts stain.

    P.S. I probably should have also asked you if you have honed (ground or polished smooth) slate or cleft top.

    I wouldn't start " Try experimenting with various poultice remedies." you may find that different things will actually chemically etch the surface and make matters worse. I would recommend contacting a local stone contractor, usually most granite countertop companies either will know what to use or whom to call. but don't experiment unless its on a piece you don't care about
