For the finish of our wood products we use “Scherell´s stock oil light” provided by Klever GmbH.
It is free of any artificial ingredients and gives the wood a silky shine.
For regular maintenance the oil should be applied with a rag or a paintbrush and then rubbed in with a linen cloth (lintless) or with the ball of your thumb. The emerging heat enables the oil to sink into the pores and still allows the wood to absorb and evaporate moisture.
The more often you repeat this procedure, the classier the surface will become.
