The Harvia Sauna Care Set includes a bottle of sauna cleanser and disinfectant (500 ml), paraffin oil (500 ml), a sponge for cleaning and spreading the fluids, as well as protective gloves and sandpaper. The bottle of paraffin oil is sufficient to treat an area about 5-10 m2. Instructions for use: Wash your sauna with 1 dl of sauna cleanser and disinfectant and 10 litres of water. Wash the wood surfaces with the sponge using the protective gloves. If dirt is embedded in the benches, you can sandpaper it in the direction of the wood fibres using the sandpaper provided in the package. After washing, rinse the wood surfaces with water and dry them carefully. Heating up the sauna speeds up the drying process.Protecting the wood surfaces with paraffin oil reduces the amount of moisture and dirt absorbed by the wood and enhances the shades of the wood surfaces. Paraffin oil is suitable for all wood surfaces, especially for heat-treated wood and older surfaces. Test the oil on the undersurface of a bench first in order to see how the shade the wood changes and whether the new shade is what you want. Wood is always unique, and the final result can be affected by things like age, porosity and the original shade of the surface.The wooden surfaces must be completely dry before you start the treatment. Put the gloves on to protect your hands, pour the paraffin oil onto the sponge and spread it evenly. Let it stand for ? - 1 hour and then wipe the surface dry if necessary. Heating up the sauna speeds up the drying process.
