Apply a penetrating finish
Membrane (film-forming) finishes, such as lacquer, polyurethane, and friction polish, rub off with use, leaving the piece unprotected and unattractive. For best protection, use a food-safe mineral or nut oil that deeply penetrates the wood. Apply the oil as shown.
"For ultimate protection," renowned woodturner Mike Mahoney reveals, "I use a special utility finish made by blending filtered, heat-treated walnut oil and waxes. Unlike mineral or untreated nut oils that evaporate over time, this oil deeply penetrates and hardens, leaving a super-durable finish." After the finish dries, Mike applies a special oil/wax topcoat that adds a lustrous satin sheen.
