Razors and brushes with wooden handles not only look beautiful but also feel pleasant in the hand. However, to ensure that this high-quality natural material brings long-lasting enjoyment, it requires a bit of care. To preserve the natural surface as much as possible, woods such as olive, ash, or plum are only lightly oiled at the MÜHLE workshop. Over time, water and soap can cause them to become brittle. That’s why they should be re-oiled every three to four weeks, depending on usage. Linseed oil or a special maintenance oil for materials is ideal for this.

Particularly recommended is the universal oil from the heritage South German company Ballistol. The company has extensive experience—after all, it was originally commissioned to develop a care oil for the imperial army that would preserve all parts of a weapon while also treating minor wounds on soldiers and horses. Ballistol succeeded and has not changed its original formula since 1904. To this day, the universal oil is used for a wide variety of materials: it continuously enhances the natural grain of wood, protects metal parts from corrosion, and is especially gentle on the skin.
