While I was in college at the University of MO- Columbia I worked for the Poultry Dept one summer. One of my duties was to gather eggs from the hen house which contained hens not being studied for feed rationing or other experiments. The eggs were gathered from nesting boxes into wire buckets. The wire buckets fit into larger tanks(the size of mop buckets) of water to which some cleaning agent was added, then the power was turned on. It was a sonicator which vibrated for 30 minutes, cleaning the eggs. The basket held 6-8 doz eggs. You might be able to find something like this at a commercial vendor site.
