How to clean Slate

Cleaning slate comes down to one rule: pH-neutral cleaners and soft tools. Slate is a fine-grained metamorphic stone that splits into flat sheets. Its cleft surface is naturally slip-resistant, making it a favorite for floors, fireplaces, and roofing.

How to clean Slate

What you'll need

  • pH-neutral stone cleaner (or a few drops of dish soap in warm water as a backup)
  • Two soft microfiber cloths
  • Warm distilled water
  • Soft bristled brush for textured surfaces

Step-by-step

  1. 1Dust or sweep loose debris off the surface — grit acts like sandpaper under a cloth.
  2. 2Spray the stone cleaner directly on the surface (not the cloth) and let it dwell 15–30 seconds.
  3. 3Wipe with a damp microfiber in light overlapping passes — never scrub.
  4. 4Rinse with a clean cloth and warm distilled water to remove cleaner residue.
  5. 5Buff dry with the second microfiber to prevent water spots.
  6. 6pH-neutral cleaner; dry buff.

Do not use

  • BleachStrips sealer and can discolor the surface.
  • Abrasive scrub pads or scouring powderScratches the finish.
  • All-purpose sprays not labeled stone-safeMost contain solvents or acids that damage natural stone.
