Apply Harvia Paraffin Oil to clean, completely dry sauna wood to help protect benches and other interior surfaces from moisture and dirt absorption. For best results, spread a thin, even coat across the surface, paying extra attention to the end sections of benches where absorption is typically highest. Let the oil sit for 30 minutes to 1 hour so it can penetrate the wood, then wipe away any excess residue.
Use it as a preventative treatment on new benches before the first session, and reapply once or twice per year as part of your regular sauna cleaning routine to maintain the wood’s appearance and extend surface longevity.
