Abrasives and Polishing Products for the Perfect Instrument Finish

Abrasives and polishing products are essential companions in violin making – from the first sanding of the wood to the final gloss of the varnish. In this category, you’ll find a carefully selected range of high-quality items: sandpaper in various grits for precise work, flexible sanding sponges for hard-to-reach areas, fine polishing powders for smoothing and matting surfaces, the trusted JOHA® Sanding and Polishing Paste for even, finely controlled surface preparation, and JOHA® Polish and Care Gloss for gentle polishing and a deep, natural shine.

All materials are specially designed for the delicate surfaces of string instruments and allow for controlled, professional handling. Whether you're performing an intermediate sanding between varnish layers or the final polishing step – our abrasives and polishing agents give your instrument a flawless finish – both visually and to the touch.

Size: 100 ml

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. Test on an inconspicuous area first (especially on delicate or matte finishes). Advantages • Suitable for all varnished string instruments • Produces high gloss and lasting protection • Gently cleans and preserves • Free from aggressive solvents • Creates a smooth, brilliant surface Available sizes: 100 ml, 250 ml, 500 ml, 1 liter Made in Germany
