Frequently asked questions

It is recommended to replace plastic cutting boards with deep cuts and grooves as bacteria can harbor in these crevices. To maintain and prolong the life of your plastic cutting board, regular cleaning and disinfection are key. Use hot water and soap to clean the board after each use, and consider using a disinfectant spray or wipe for added sanitation.

Besides regular washing with soap and hot water, there are a few additional methods to sanitize your plastic cutting board. One effective approach is to use a diluted bleach solution (around 1 teaspoon of bleach per quart of water) and let the board soak in this solution for a few minutes before rinsing it thoroughly. Alternatively, you can create a natural disinfectant by mixing lemon juice and salt, then scrubbing the board with this mixture before rinsing it off.

Oiling your plastic cutting board is not necessary, as plastic boards don’t absorb moisture like wooden ones. However, if you wish to condition the board, you can apply a thin layer of mineral oil or a food-grade oil like walnut oil. Do this occasionally, and always ensure you wipe off any excess oil with a clean cloth.

Definitely replace your plastic cutting board if you notice deep cuts or grooves that are hard to clean, if the board develops a persistent odor even after cleaning, or if it becomes warped or excessively stained. Additionally, if you’ve been using the same board for several years, it’s a good idea to replace it, as plastic boards can break down over time, potentially releasing small pieces of plastic into your food.

Wooden cutting boards, particularly those made from hardwoods like maple or walnut, are a great alternative to plastic. They are durable, self-healing (meaning they close up around knife cuts), and gentle on knives. End-grain wooden boards are especially long-lasting. Another option is a composite material board, which combines wood fibers with plastic resins, offering the benefits of both wood and plastic.
