Plastic cutting boards are an affordable option but require regular cleaning. They can develop big cuts and gashes that harbor bacteria. Washing them in the dishwasher may cause warping, so it's better to clean them by hand. For heavily stained and unsanitary boards, bleach can be used. A teaspoon mixed with four cups of water should be used to scrub the board. If bleach is not preferred, lemon juice can be used as a natural antibacterial agent. Another option is a mixture of baking soda, dish soap, and hydrogen peroxide. However, bleach provides the best results in terms of cleanliness.
