The Petz polish has been developed to complement the proven Rosin remover. The Petz polish is made from pine oil and beeswax, which is excellently suited to cleaning and caring for delicate string instruments surfaces without creating a new dirt-attracting layer. Unlike the Petz rosin remover, which is mainly used for removing stubborn dirt deposits, the Petz polish can be applied on a more freuquent basis. Country of origin: Austria
