How to clean black slate

Black slate is a beautiful option for floors, countertops and other household surfaces. In addition to being beautiful, black slate is one of the most durable and stain resistant stones on the market. Like any other surface, slate should be periodically cleaned. The product you use is largely up to you. Slate is practically non-porous so it can stand up to even the harshest chemicals. If you are cleaning black slate tiles on a floor, however, stay away from highly acidic or alkaline products as they may damage the grout.

  1. 1

    Dilute the cleaning solution in a bucket (if necessary) according to the manufacturer's instructions for a strong solution.

  2. 2

    Wet a small area of the black slate with the cleaning solution.

  3. 3

    Leave the cleaning solution to soften the dirt and grime for five minutes.

  4. 4

    Wet your scrub brush with cleaning solution.

  5. 5

    Scrub the area clean. Re-wet the scrub brush as necessary.

  6. 6

    Wipe away the residual cleaning solution with a mop or sponge and a supply of fresh, clean water.

  7. 7

    Dry any excess moisture with a dry mop or towel if desired. Or, allow the black slate to air dry.

Tips and warnings

  • Sweep black slate floors frequently. Dust and dirt tracked through the house will prematurely wear away the finish.
  • Abrasive, granular cleaning solution will streak black slate floors, requiring an extra freshwater rinse. To avoid this, use only clear liquid cleansers.
  • Never use metal bristle brushes or metal scouring pads to clean your black slate; you may abrade the surface.
