Care & Maintenance

Love your surfaces for a lifetime.

At Landmark Countertops, we know your countertops are more than a surface—they’re part of your home, your family meals, your celebrations, and your everyday moments. That’s why caring for them is about more than just cleaning—it’s about preserving the beauty and integrity of the materials you’ve chosen.

Here’s everything you need to keep your surfaces looking as beautiful as the day they were installed.

Granite Countertops

Natural strength and one-of-a-kind beauty

  • Seal every 1–3 years, depending on usage.
  • Clean with pH-neutral stone cleaner—avoid harsh or acidic products.
  • Always use trivets and cutting boards.
  • Wipe spills immediately, especially oils, wines, and acidic foods.

Quartz Countertops

Modern style meets low-maintenance living

  • No sealing required—quartz is nonporous.
  • Clean daily with warm, soapy water or mild household cleaners.
  • Avoid abrasives, oven cleaner, and bleach.
  • Use trivets for hot cookware and cutting boards for food prep.
  • Wipe spills promptly to prevent potential staining.

Marble Countertops

Classic elegance with natural veining

  • Seal yearly or as needed.
  • Use only stone-safe, pH-neutral cleaners.
  • Coasters, trivets, and cutting boards are essential—marble is sensitive to acids and heat.
  • Blot spills immediately to avoid etching.

Quartzite Countertops

Natural beauty with impressive durability

  • Seal every 1–2 years; test regularly using the water drop method.
  • Clean with pH-neutral cleaners—never harsh chemicals.
  • Use trivets and cutting boards to prevent wear.
  • Wipe spills promptly—quartzite is durable but still porous.

Porcelain Countertops (Dekton® and similar)

Ultra-durable, sleek, and low maintenance

  • No sealing needed—porcelain is nonporous.
  • Clean with warm water and mild detergent.
  • Avoid scouring pads and harsh chemicals.
  • Use trivets to prevent sudden thermal shock.
  • Dark porcelain may show fingerprints—wipe dry after cleaning.
  • For stubborn marks, use a non-abrasive cream cleaner.
