Plastic cutting boards are kitchen workhorses. They’re durable, affordable, and relatively easy to clean. However, over time, they can become stained and discolored, especially from vibrant foods like beets, berries, and sauces. A once pristine white cutting board can quickly become a canvas of unsightly marks. But don’t despair! You don’t need to toss it and buy a new one. With the right techniques and a little elbow grease, you can restore your plastic cutting board to its former glory. This guide provides comprehensive instructions and tips to effectively whiten your stained plastic cutting board.
Understanding the Stains and Why They Appear
Before diving into cleaning methods, it’s helpful to understand why plastic cutting boards stain in the first place. Plastic, particularly polyethylene (PE) and polypropylene (PP), which are commonly used in cutting board manufacturing, is porous to some degree. This means that microscopic particles of food, dyes, and pigments can seep into the surface.
Furthermore, the rough surface created by knife marks offers even more nooks and crannies for stains to settle in. This is why older, more heavily used cutting boards tend to be more stained than newer ones. Certain food compounds also react with the plastic over time, causing discoloration.
Finally, neglecting to clean your cutting board immediately after use exacerbates the problem. Allowing food residue to sit on the surface gives it more time to penetrate the plastic and create stubborn stains. Regular and prompt cleaning is crucial in preventing severe discoloration.
