This quick and easy-to-use kit is ideal for cleaning platinum, gold and diamond jewellery, and most precious stones. Place your jewellery in the Basket and dip it into the Cleaning Fluid. Check your jewellery after two minutes and, if necessary, repeat the process until your jewellery is clean. Do not leave items immersed for long periods. Remove any embedded dirt with the brush, and dry with a soft, clean cloth. Replace when the liquid becomes cloudy. Caution: Do not use this cleaner on emeralds, opals, corals, pearls, paste stones or costume jewellery.
