For liquids such as pickle juice and milk, simply place a microfiber cloth on the spill and wipe it up. Even better, the microfibers are slightly abrasive, so if the jam jar has left a ring on the refrigerator shelf, wet the cloth with warm water and gently scrub the jam away. To get rid of meat and poultry juices, use paper towels soaked with a diluted solution of bleach and water, since juices from meats can carry bacterial contaminants that can remain trapped in cloth dish towels and microfiber towels.
