Harvia’s Paraffin Oil is a trusted treatment for interior sauna wood surfaces, most commonly used on benches. Paraffin oil helps reduce moisture and dirt absorption of any wood to enhance the lifespan and protect your investment. Harvia is safe on heat treated and natural woods like alder, aspen, thermo-aspen, thermo-spruce, and western red cedar. Harvia recommends you protect the benches and other frequently contacted surfaces with paraffin oil 1-3 times a year.
