Before finalizing your decision to add a stainless steel and wood combo countertop to your kitchen island, consider the maintenance requirements. Stainless steel countertops are generally easy to clean and maintain, but they can show fingerprints and scratches more easily. Wood countertops require regular sealing and maintenance to protect them from moisture and stains. Assess your willingness to invest time and effort into the upkeep of the materials before making a final decision.
