You just need enough to cover the jewelry you're cleaning. This method works as a gentle cleanser that removes tarnish without abrading the silver. If your silver is lightly tarnished, the salt bath should take the tarnish right off.  If you're cleaning a lot of jewelry at once, you can use more water. For just one piece of jewelry, use less water. If your jewelry has gemstones, make sure they won't be affected by being submerged in a saltwater solution. This solution is gentle on most stones, but if you're cleaning very fine jewelry with expensive gemstones, you're better off taking it to a professional just in case. You can also contact your jeweler for advice.
