Most boards get more dangerous the longer you own them
Every knife stroke leaves a groove. On wood and plastic, those grooves are exactly where last week's raw chicken, garlic and fish juices go to hide — somewhere your sponge can't reach. Wood absorbs moisture and grows mold from the inside out. Plastic dulls, scores, stains, holds onto smells, and quietly sheds tiny particles into the food you're feeding your family.
You can scrub all you want. Porous is porous. A scored plastic board can hold more bacteria in its grooves than a freshly used one — because the grooves never fully clean.
Forva fixes the actual problem: the surface.
