I picked up three 94's at fall Hershey cheap for parts. With nothing much to lose I thought I would try out the Simple Green in a Crock Pot method. After much research I was not sure what the results would be so I started with the one in the worst shape. Here are the materials: Here is the victim: After 12 hours on high and a little tooth brush work here are the results. Will probably do it again after dis-assembly in a clean solution but at least I can take them apart without needing a bath. BTW the throttle shaft was stuck before and free after for all three. Total cost $6 for the bottle of Simple Green.
