Countertops made of heart pine offer homeowners the beauty of wood for less money than countertops made of cherry, oak or mahogany. Heart pine wood hardens as the tree sap in the center of the trunk crystallizes with the cell wall, making it exceptionally strong and resistant to insects and disease.
Protect your heart pine countertops by applying an oil-based finish to the wood. You can buy an appropriate product from any home improvement store. Apply it to the wood according to the directions on the label. When the finish penetrates the wood, it will protect your countertops from stains and water damage and make them easy to wipe down.
To maintain the finish, apply another coat of the oil-based finish once a year. Leave it on for a few minutes, buff the excess off with a clean rag and let it dry for about 30 minutes. The hour you spend each year refinishing the countertops is a small price to pay to protect your investment. Clean the countertops regularly with soap and water, and dry them immediately afterward to prevent standing water from damaging the wood. Never scrub wood counters with a scouring pad that may scratch or otherwise damage the surface.
Clean the surface well after each use if you prepare food directly on the wood to kill any bacteria. The U.S. Department of Agriculture recommends spraying a solution of 1 tbsp. liquid chlorine bleach mixed with 1 gallon water on the countertop, rinsing it with clean water and patting it dry with a cloth or paper towel. To prevent bacteria from damaging your countertops or cross-contaminating your food, prepare food on cutting boards instead of directly on the countertop.
Light, oxygen and regular wear will cause your countertops to darken. The patina enhances the appearance of the material. You will notice that your countertops take on a richness as they age. With regular care and maintenance, your countertops made of heart pine will reward you with improved performance and beauty.
