- For stubborn stains, reapply cleaner and use light pressure with the brush, avoiding harsh scrubbing that could scratch the surface.
- Rinse the area with clean water or a damp cloth to remove cleaner residue, then dry thoroughly with a fresh microfiber cloth.
- Inspect the surface for remaining marks. If needed, repeat the cleaning cycle on localized spots.
- Apply a slate stone sealer protector after the surface is completely dry to help repel stains and water infiltration.
- Allow the sealer to cure per manufacturer guidance before allowing foot traffic or placing items on the surface.
- Periodic maintenance: clean with the same routine and re-seal as recommended by the sealer manufacturer to maintain a protective barrier.
- Store cleaning products and tools in a cool, dry place away from direct sunlight to preserve effectiveness.
- Keep pets and children away from freshly cleaned and sealed areas until fully cured.
