Toothpaste – Toothpaste is non-toxic and should be used exclusively for silver jewelry. Put a dime sized amount on your finger and apply in a circular motion on the object of your affection. After a minute, clean off toothpaste with warm water and wipe dry with a dry cloth. (I have been doing this with silver pieces and toothpaste works wonders!)
Baking soda – Cleaning with baking soda should be used exclusively for sterling silver jewelry. Line a glass or plastic dish with a slightly crumpled piece of aluminum foil. Lay your jewelry on top of the foil and sprinkle baking soda over each piece. Pour enough boiling water to immerse the jewelry. Bubbling should occur, giving off a rotten-egg odor. With a wood or plastic utensil, gently move the pieces around to ensure that all of the silver surfaces come in contact with the aluminum. You will notice that the silver has become bright again. Rinse your pieces under tap water and rub dry with a dry cloth. (I heard about this but never tried it before!)
Shampoo – Mix with warm water; specific to pearls. Boil water in a pot with a little shampoo for 10 minutes. Then scrub very gently with a soft toothbrush, rinse with cold water and leave to dry on a towel or paper towel. (I didn't know but would try it in the near future.)
***DO NOT boil pearls for 10 minutes. ONLY use the solution to clean pearls gently with soft toothbrush.
Vinegar – Mix with water and use a soft toothbrush to clean; for silver or gold jewelry. Place the vinegar in a small jar put your jewelry inside. Let the items soak for about 15-20 minutes. Shake the jar gently for a few seconds, then remove items and gently brush them with warm water. (Have to try in the future)
Dish Detergent – Mix with warm water; for delicate silver or gold jewelry. For your most delicate pieces, use unscented dish soap and warm water. Dip a dry rag or soft bristled toothbrush to clean these pieces. (Heard about this before but never try before)
*I have not tried some of the methods mentioned here so please use caution and try it on less expensive pieces first to see the result for yourself before cleansing family heirloom pieces.
