Cambria is much harder than granite or marble making it more durable. That means Cambria is less likely to scratch, chip, or stain for years of worry-free service. Other natural stone surfaces like granite and marble require regular sealing and polishing. With Cambria, all you need to do is wipe it down with a little warm water and mild soap. Cambria is nonporous and nonabsorbent so it won’t draw in moisture from raw or leftover food, which can harbor harmful bacteria.
