Over time, jewellery can lose its lustre by becoming soiled with skin oils, dirt and soap residue. An effective method of keeping your rings, bracelets and necklaces clean and shiny is to use an ultrasonic cleaner. Ultrasonic cleaners send sound waves through the cleaning solution bath, causing microscopic bubbles to gently clean your jewellery. The cleaning solution is little more than a mixture of common household chemicals. In minutes you can easily make your own.

Things you need
- Nonmetallic bowl
- Nonmetallic spoon
- 1 cup hot water (hot bath temp)

Assemble supplies. You must exercise caution in handling ammonia. Even at concentrations used for household cleaners, ammonia fumes can damage respiratory membranes and burn the skin and eyes.
Combine hot water, ammonia and dish washing detergent in bowl. Mix thoroughly with a nonmetallic spoon.
Pour the cleaning solution into the ultrasonic bath tank. Place jewellery into tank and turn the unit on, per manufacturer's directions. After cleaning cycle is complete, remove jewellery, rinse with warm water and dry with a lint-free cloth.
