Pearls, the treasures of the sea or man made, need careful attention to maintain their lustre. Acecroft's Chemist devised a gentle aqueous solution to clean and enhance that lustre. Using the plastic basket provided to hold the pearls, simply lower them into the inca™ Pearl Cleaner and leave for 3 - 4 minutes, gently rotating from time to time. Remove, rinse and pat dry with a soft lint free cloth. The lustre is returned to the pearls without harming clasps or threads.
