Caring for your ET ACRI block

To ensure your ET ACRI block lasts long and can protect and sharpen your knives for many years, we recommend the following after care.

  • A sealant will repel staining agents but doesn’t make marble stain-proof. You can test if you need to reseal by dropping water on the surface – if the water no longer beads, it’s time to reseal.

  • Vinegar, citrus, and tomato will corrode marble; don’t let it sit on the stone. Wipe up spills immediately.

  • Avoid using acidic or abrasive cleaners.

  • To remove stubborn stains, use a poultice paste. Spread it onto the stain, then cover with plastic wrap sealed with painters’ tape. Once it’s dry (12 to 24 hours), scrape the paste off and wipe with a damp cloth. For deep-set stains, you may need to reapply paste.

  • Apply a soap mix onto your oiled block (with as little water as possible). After letting the soap sit briefly on the oiled wood block to dissolve any dirt, make sure to clean up any dirty soap water.

  • Reapply oil when needed.

  • Concrete is vulnerable to staining and etching from citrus, red wine, and oil, but you can mitigate this by making sure the surface is properly sealed.

  • Use only plain water to clean the concrete.

  • Be sure to choose a heavy-duty sealer that is food-safe, colourless, non-yellowing, and heat and scratch resistant.

  • Exposure to direct sunlight will darken “blonde” colors and bleach darker colors. Premium vegetable tanned leather will age gracefully, developing a beautiful patina with use over time.

  • If the leather is exposed to hot, dry air that can dry out leather we recommend to regularly condition the leather.

  • Avoid chemicals and detergents that can damage the surface of the leather and tarnish the color.

  • Use a cleaning and polishing agent for steel, liquid detergent or all-purpose cleaner. Rinse with clean water and wipe with a soft, nipple free cloth.

  • Use vinegar to remove stains of hard water.
