Slate is a type of metamorphic rock that is often used as a building material in homes and yards. Some hearths are made of slate because of its attractive, natural-looking features.

Step 1

Wipe down the slate with a damp cloth to remove any dust or debris before polishing. Allow the slate to air dry completely.

Step 2

Squirt a few drops of teak oil onto a clean, dry cloth. You can find teak oil at many home improvement stores. You also can use citrus oil for polishing slate.


Step 3

Apply the oil to the slate hearth with small, circular motions.

Step 4

Rub the slate once more to buff in an extra shine. This time use a clean, dry cloth. This will help to absorb excess oil and will accentuate the luster of the slate.
