Washing your hands beforehand ensures that you won’t spread more germs when you’re cleaning your earrings. Run your hands under warm water, then lather them up with hand soap for 20 seconds. Rinse them again and dry with a clean towel. Make sure to wash between your fingers and up to your wrists. Cleaning your earrings with hot water is perfect for when you’re short on supplies and just need your jewelry a little shinier. To start, pour a couple cups of water into a pot on the stove and heat it until it’s just boiling.  You can also heat the water in a mug in the microwave. Start by heating it for 1 minute and 30 seconds, then check and continue heating it as necessary. Cleaning with hot water won’t get your earrings quite as clean as a solution would, but it’s a good method for when you’re low on cleaning supplies. Remove the water from the heat and drop the earrings inside. Let them sit in the water for about 20 minutes to get clean.  The hot water will kill germs and loosen dirt from the surface of your earrings. Hot water is safe for all earrings. If you’re cleaning costume-style plastic earrings, you can wait a minute or so for it to cool before placing the earrings in. Lift your earrings out with a spoon or with your hand, if the water is cool enough. Gently scrub them with an old toothbrush, going one at a time to brush free any remaining dirt. Rinse the earrings with warm water when you’re done. Let the earrings sit for a few minutes, or until they’re dry. You can also pat them a couple of times with the towel to get rid of any excess water drops. Touch them to see when they’re dry and ready to be put away or worn.
