JOHA® Cleaning and Care Products

The JOHA® cleaning and care products are high-quality formulations developed in-house, designed for the gentle maintenance of fine string and plucked instruments. With the JOHA® cleaning fluid, you can reliably remove rosin, dust and other residues without damaging the delicate varnish. It cleans thoroughly and prepares the surface for optimal care. The JOHA® care polish then restores a brilliant shine. It forms a thin protective layer that preserves the gloss, nourishes the wood, and offers long-lasting surface protection. Perfect for regular maintenance – easy to apply, highly effective. JOHA® – for the preservation and beauty of your instrument.
