TURQUOISE CARE
To clean your turquoise jewelry, use either a soft toothbrush in water to gently scrub the piece, or a jewelry polishing cloth.
Always remove your turquoise rings and bracelets before washing dishes, gardening, painting the walls, automotive repairs or any other household dirty work. Household bleach can radically and permanently affect the color of turquoise.
Hand lotion can change the color of a stone. So put on any perfume, lotions, etc. first, then put on your turquoise.
Never use an ultrasonic jewelry cleaner on your turquoise.
Don't wear turquoise in the swimming pool or hot tub, as the chlorine or bromine used in keeping the pool clean, can dramatically affect its color.
Don't wear turquoise in the shower because soaps can affect it.
If possible, avoid the use of chemical silver polishes with turquoise jewelry or be very, very careful not to get them on the stone. The acids present in some chemical polishes can change your stone's color as well.
