A traditional sauna is typically heated by a sauna stove or heater. The most common type is a wood - burning stove, but electric heaters are also widely used. The stove is usually made of metal and is designed to withstand high temperatures.

After each use, use a soft, damp cloth to wipe the interior surfaces of the sauna, including the benches, walls, and floor. This helps to remove sweat, dirt, and other residues. Pay special attention to areas where people touch or sit, as these can accumulate more grime.
