Cleaning Liquid Silver
If you have liquid silver or heishi strands that are getting tarnished, there's an easy way to make them shine again. Place a cotton towel or washcloth in the palm or your hand; generously sprinkle the towel with baking powder. Guide the strands through the towel, rubbing gently as you pull them through. You may have to guide the strands through a few times; shake the strands gently to remove excess powder. Because liquid silver is commonly strung on thread, you should use care not to pull the strand too hard. You could break the string or stretch it, effecting the overall appearance.
