How to Make a Wooden Chopping Board Water-Resistant

A wooden chopping board is a kitchen staple that is not only functional but also adds an aesthetic touch to your kitchen. However, with regular use, a wooden chopping board can lose its water resistance, making it prone to warping, cracking, and bacterial growth. In this article, we will discuss how to make a wooden chopping board water-resistant so that it lasts longer and stays hygienic.

Choose the Right Type of Wood

The type of wood you choose for your chopping board plays a vital role in determining its water resistance. Hardwoods such as maple, oak, and cherry are good options because they are dense and have a tight grain structure. Avoid softwoods like pine or cedar, as they are more porous and prone to absorbing water.

Prep the Board

Before applying any treatment, it is essential to prep the chopping board properly. Start by giving it a good wash with warm soapy water to remove any dirt, grime, or bacteria. Rinse the board thoroughly and allow it to dry completely. You can also use a food-safe disinfectant or vinegar solution to sanitize the board.

Sand the Board

Once the board is dry, use fine-grit sandpaper to smooth out any rough spots or scratches on the surface. Sanding the board not only makes it look better but also creates a smooth surface for the treatment to adhere to. Make sure to sand with the grain of the wood, and wipe away any dust with a clean cloth.

Apply Mineral Oil

Mineral oil is a popular choice for treating wooden chopping boards because it is food safe, affordable, and easy to apply. It also penetrates deep into the wood, helping to protect it from moisture. To apply, pour a small amount of mineral oil onto the board and spread it evenly with a clean cloth or brush. Make sure to cover the entire surface, including the edges and corners. Let the oil soak in for a few hours or overnight.

Remove Excess Oil

After the oil has had time to soak in, use a clean cloth to wipe away any excess oil. It is essential to remove any excess oil, as it can turn rancid over time and affect the taste and smell of your food. You can also use a plastic scraper to remove any stubborn spots.

Repeat the Process

To ensure maximum water resistance, it is recommended to repeat the oiling process every few months or as needed. Regular oiling helps to maintain the board's moisture barrier and prevent it from drying out or cracking. However, avoid over-oiling the board, as this can cause it to become too greasy and attract dirt and bacteria.

Consider Using Beeswax

Another option for making a wooden chopping board water-resistant is to use beeswax. Beeswax is a natural wax that repels water and helps to seal the wood's pores. To apply, heat the beeswax in a double boiler until it melts. Then, use a clean cloth to apply the wax to the board in a thin, even layer. Let the wax cool and harden for a few hours before buffing it with a clean cloth.


A wooden chopping board is an essential tool in any kitchen, but it requires proper care and maintenance to ensure its longevity and hygienic properties. By choosing the right type of wood, prepping the board, and applying mineral oil or beeswax, you can make your chopping board water-resistant and protect it from damage caused by moisture. Regular maintenance, including oiling and cleaning, will help keep your board in good condition and prevent it from harboring harmful bacteria. With these simple tips, your wooden chopping board will be a reliable and durable kitchen tool for years to come.
