At Latham & Neve we use silver cleaning dips and cloths from Town Talk, an established British company renowned for their quality products.For cleaning stubborn areas and recesses dipping a cotton bud or an old soft tooth brush in silver dip is usually effective. On matt/satin and textured surfaces we also recommend cleaning with a soft tooth brush with silver dip or alternatively a small abrasive pad can be used (ensure all recesses of the jewellery are clean and dry).
