The Harvia Sauna Care Set is designed for treating the wood surfaces of the sauna and cleaning the sauna facilities. The Harvia Sauna Care Set includes one bottle of cleanser and disinfectant for the sauna (500 ml), paraffin oil (500 ml), a sponge, protective gloves and sandpaper. First, wash your sauna as instructed using the sponge and protective gloves. If necessary, use the sandpaper to remove persistent dirt. Rinse the wood surfaces and let them dry. After that, you can protect the surfaces with paraffin oil, which will also beautifully accentuate thelour of the wood.
