Suma Block Whitener Liquid Cleaner for Cutting Boards - Fast Whitening

Our review of the Suma Block Whitener finds it best suited to kitchens and food processing areas that need a straightforward, professional-strength solution for stained plastic cutting boards. The product's single biggest selling point is its thick, high-alkaline formula that begins working on contact and can visibly whiten and brighten boards in as little as 15 minutes. For anyone responsible for maintaining hygiene and appearance on plastic chopping blocks, sushi blocks or other food prep surfaces, this cleaner delivers targeted whitening without the need for abrasive scrubbing when used according to directions.

Key Features

• Designed for food prep surfaces: Specifically formulated for plastic chopping boards, sushi blocks and other food contact surfaces used in commercial kitchens.

Who It's For

This cleaner is aimed at commercial kitchens, food processors and institutional janitorial teams that need a reliable product to restore and maintain plastic cutting boards. The concentrated, professional strength chemistry and certifications make it a practical choice for restaurants, catering operations and foodservice facilities that require NSF-listed cleaners for food contact surfaces.

Home cooks with heavy use boards can also benefit if they want fast whitening and a product intended for food preparation surfaces, but those seeking mild, everyday household cleaners or fragrance-free, highly diluted options may prefer gentler alternatives.
