🪵 Natural Slate Care & Maintenance

Crafted from natural stone, our slate products offer a rugged, elegant aesthetic. Because slate is a porous, textured material, it requires a mindful approach to care depending on whether it lives indoors or outdoors.

Indoor Slate & Coasters

  • Routine Cleaning: Wipe the surface with a soft, damp cloth. Because slate is porous, catching spills early prevents liquids from settling into the stone.
  • Deep Cleaning (Stains): If your coasters get stubborn coffee or tea rings, scrub them using a baking soda and water paste with a soft cloth or a soft-bristled toothbrush, then rinse and dry completely.
  • A Note on Scouring Pads: While a scouring pad can be used to scrub away stubborn residue in a pinch, keep it light. Over time, heavy abrasive scrubbing will dull the natural contrast of the stone and the engraving.

Outdoor Plaques & Memorials

  • The “Vanishing” Rain Effect: Don’t alarm if your outdoor memorial seems to disappear during a rainstorm! Because we leave our slate completely natural to preserve maximum image contrast, water temporarily fills the microscopic laser fractures. As soon as the stone dries out in the sun, the bright white engraving will snap right back to full brightness.
  • Seasonal Refresh: If exposed to the elements year-round, environmental dust, pollen, or light mildew can settle into the engraved textures over time. A quick, gentle scrub with warm water, mild dish soap, and a nylon brush once a year will clean out the recesses and keep the image crisp.

⚠️ CRITICAL WARNING ON MINERAL OIL & SEALERS: While some sources suggest mineral oil or clear coats to restore stone sheen or “protect” it outside, we strongly advise against using them on engraved slate. Because the stone is highly porous, liquid sealers or oils soak into the microscopic crevices and completely obliterate the contrast of your design, permanently flattening out the image. Leave the stone natural for the best look.

Handling with Care

Avoid dropping or knocking slate against hard surfaces, as the natural edges can chip under heavy impact. Never place any slate products in a dishwasher.

This keeps your existing warnings intact, clarifies the “disappearing” act so customers don’t panic when it rains, and gives them a clear, easy way to keep their memorials looking fresh.
