How To Maintain Cedar Planks For Long-Term Use?

April 5, 2026

Quick Answer

To maintain cedar planks for long-term use, regularly clean and store them in a dry, well-ventilated area, and apply a food-safe sealant when necessary. This will prevent warping, cracking, and bacterial growth. Proper care will extend the lifespan of the planks.

Preparing and Storing Cedar Planks

Before using cedar planks for cooking, inspect them for any signs of damage, decay, or warping. Clean the planks with mild soap and water, and dry them thoroughly with a towel or let them air dry. Store the planks in a dry, well-ventilated area, away from direct sunlight and moisture. Consider stacking the planks on a flat surface, with a sheet of parchment paper or a cloth barrier between each plank to prevent scratching.

Cleaning and Sealing Cedar Planks

To maintain the cleanliness of the cedar planks, clean them with a mixture of equal parts water and white vinegar after each use. This will help prevent bacterial growth and maintain the natural oils of the cedar. If the planks develop a stubborn stain or odor, mix baking soda and water to create a paste, and apply it to the affected area. Let the paste sit for 30 minutes before rinsing and drying. Apply a food-safe sealant, such as beeswax or plant-based oil, to the planks every 6-12 months to protect them from warping and cracking.

Handling and Cooking with Cedar Planks

When handling cedar planks, avoid touching the surface with your bare hands, as the oils from your skin can transfer to the wood. Always use a utensil or tongs to place the planks on a preheated grill or oven. When cooking fish or other delicate foods, place them directly onto the cedar plank, and cook at a medium-low temperature (around 350°F) for 8-12 minutes, or until the food is cooked through.
