Slow Tarnish
Olive oil won't stop silver from tarnishing but it will keep it shiny longer. Just a dab of oil on a soft cloth rubbed over polished silver will slow the oxidation that brings on tarnish.
Mix 1 teaspoon dishwashing liquid and 1 cup warm water. Add 1/2 teaspoon of ammonia based household cleaner (like a glass cleaner such as Windex) Soak your jewelry in the solution for about 5 minutes & then gently scrub with a soft-toothbrush. Air dry or carefully towel-dry with paper towel or regular cloth.
Jewelers use ultrasonic cleaners with high frequency sound waves and chemicals, which create bubbles that latch on to the dirt on the diamond. The high frequency sound waves pull the dirt away from the stone and bring them up to the surface.
Baking soda, salt and aluminum foil.
Lay all of your darkened costume jewelry on the foil. Mix one tablespoon salt and one tablespoon of baking soda and mix with one cup warm water. Pour into the dish. The mixture will create a chemical reaction with the foil and bubble as it cleans the jewelry.
Hot water is an easy (and cheap) cleaning solution for hard metal jewelry. Steam and heat loosen dirt and debris from jewelry, making it a snap to wipe away. Simply place your pieces in a heatproof container, then slowly pour in boiling water until they're covered.
Vinegar is another popular at-home solution for cleaning. But like lemon juice, vinegar is very acidic and will cause damage to your soft stones and plated jewelry. Soaking your jewelry in a bowl of vinegar will remove the jewelry's shine and finish.
Combine Vinegar and Baking Soda: Mix 1/2 cup white vinegar and 2 Tbsp. baking soda together, then let your silver jewelry soak in the mixture for two to three hours before rinsing and polishing.
Do not store olive oil in containers made of reactive metals such as copper or iron. The chemical reaction between the olive oil and the metal will damage the oil and may produce toxins. Olive oil should not be stored in plastic containers because the oil may absorb PVC's from the plastic.
Lemon juice and olive oil
Mix one teaspoon of olive oil with 125ml of lemon juice. You will need to dip a cloth into the earlier made mix and polish your silver. Once you achieve a wonderful shine, rinse and allow to dry.

White vinegar: Soak pieces in ½ cup of white vinegar with two tablespoons of baking soda. Lemon essential oil: Add lemon essential oil to a jewelry soak.
