It depends on the Alva cookware. Some products, like the Forest line of products, come pre-seasoned (with a mineral oil), and do not require additional oils or sprays. Other products, like the stainless steel collection, do not come with any seasoning or coating.
The best thing to do is identify the material (aluminum, stainless steel, cast iron, carbon steel), see the product page for information, and find out if the product has any type of pre-seasoning or coating on it.
