JOHA® High-gloss Cleaning and Preserving Polish For brilliant shine and long-lasting protection The JOHA® High-gloss Cleaning and Preserving Polish is specially developed to restore the original high gloss of varnished string instruments such as violins, violas, cellos, and double basses. It gently removes fingerprints, dust, and light dirt without attacking or softening the varnish. With just a few simple steps, the surface regains its brilliant shine while a protective care layer preserves the varnish from environmental influences and enhances the natural color of the instrument. This polish is also ideal for the final treatment of new varnishes, providing a perfectly smooth and radiant finish. Application Remove loose dust from the instrument. Apply a small amount of polish to a soft, clean cotton cloth and spread evenly over the varnished surface. Polish in circular motions until the polish is dry and the instrument appears glossy.
