I use a flashlight for those items. Lay it on the floor with the beam parallel, just slightly lighting the floor. It is amazing what shows up!
Note that there are some SS parts that are magnetic. My tumbler uses tiny one that are easy to pick up with a magnet. I keep finding them after a cleaning cycle!
