Sauna Wood Oil (1 Quart) is a sauna-specific, penetrating treatment created to protect interior benches, walls, and trim from daily heat and moisture while keeping the wood looking naturally rich. Formulated over two decades and meeting FDA and USP safety guidelines, this non-toxic, Kosher-certified oil is safe for hot-room use where skin contact is common. A single quart covers about 150–200 sq ft, making it ideal for residential saunas or touch-up maintenance between deeper treatments. As it soaks in, it leaves a water-repellent barrier that helps prevent staining, sweat absorption, and premature wear, so cleaning becomes faster and wood lasts longer. Infused with six aromatic oils and stabilized with Vitamin E, it adds a subtle, spa-like scent and maintains performance over time.
