How to Remove White Mould from a Wooden Cutting Board: A Comprehensive Guide

Wooden cutting boards are a popular choice among home cooks and chefs due to their durability and easy maintenance. However, even ash wood-based cutting boards can occasionally develop white mould. This article provides a step-by-step guide on how to remove and prevent this issue.

White Mould on Cutting Boards: Understanding the Issue

White mould, Zygomycetes or Sporiculasopora, is a type of mould that can grow on cutting boards, particularly those made from certain types of wood like ash. Despite this, it's worth noting that ash wood is naturally resistant to mould growth, which is why it's often used for cutting boards. Nevertheless, proper cleaning and maintenance are essential to prevent mould from developing and to eliminate any that may have taken root.

Effective Removal Methods

Using Bleach: Bleach is a highly effective solution for removing mould from wooden cutting boards. Here’s how to do it:

Dilute your chlorine bleach properly. For the ideal solution strength, mix 2 teaspoons of chlorine bleach per half gallon of warm water. This solution will effectively kill existing mould. Gently scrub your cutting board. Use a kitchen scrubbing brush to apply the bleach solution to the affected area. Scrub gently until all the mould has been taken care of. Rinse thoroughly. After scrubbing, rinse the cutting board with clean water to remove any remaining bleach. Consider preventative measures. To prevent future mould growth, regularly clean your cutting board with a dilute bleach solution, followed by a thorough rinse and drying. Applying a thin coat of USP mineral oil can also help seal the wood and prevent moisture retention, which is essential for mould growth.

Alternative Methods: Some chefs swear by using vinegar as a natural cleaner. White vinegar contains acetic acid, which can help prevent bacteria and mould growth. However, results may vary, and it's a good idea to test on a small, inconspicuous area before applying it to the entire board.

Maintaining Your Cutting Board

Maintaining your cutting board is key to keeping it in good condition and ensuring it remains safe to use. Here are some tips:

Regular cleaning: Clean your cutting board after each use with mild dish soap and warm water. Allow to dry completely: Ensure the board is completely dry before storing it. Moisture can lead to mould growth and other issues. Use with care: Be mindful of what you're cutting to avoid unnecessary damage. Cutting through bones or dense materials can put stress on the board, leading to cracking or splitting over time. Consider a replacement: If your cutting board shows signs of excessive wear or persistent mould, it might be time to replace it. While it's not always necessary, especially with durable woods like ash, a new cutting board can ensure continued safety and functionality.

In conclusion, removing and preventing white mould from a wooden cutting board is straightforward with the right methods and regular maintenance. By following the steps outlined in this guide, you can keep your cutting board in excellent condition and continue to prepare delicious meals for you and your loved ones.
