Do you see a stain on your pearls? Mix a half teaspoon of mild soap into one cup of lukewarm mineral water, dip the cotton puff into the mixture and gently rub the pearls. Rinse with your mineral water. Use a soft cloth to dry. Avoid ultrasonic cleaners and exposure to chemicals such as lotions, hairspray, and makeup. Your pearls need to be stored flat, never in a tangled, in a cloth-lined box. Mind the golden rule, the last thing on and first thing off, following this rule will help extend the life or your pearls.
